The operation faults of Yaskawa inverter W1000 and the solutions

(1) Operator display: oPE01

Fault name: The setting of the inverter capacity is faulty, and the setting content of O2-04 (inverter capacity selection) is inconsistent with the actual inverter capacity.

The reason is that the setting content of O2-04 (inverter capacity selection) is inconsistent with the actual inverter capacity, and the solution is to set O2-04 correctly.

(2) Operator display: oPE02

Fault Name: The parameter range is set inappropriately, and the value outside the set range is set in the parameter.

The reason is that a value outside the set range is set in the parameters, and the solution is to check which parameter in U1-18 (the parameter of the oPE fault) is set incorrectly, and set the parameter correctly.

Note: If multiple operation errors occur at the same time, other oPE □□ will be displayed before the oPE.

(3) Operator display: oPE03

Fault name: Improper selection of multi-function input, incorrect function assignment content of H1-01-H1-08 (function selection of terminals).

The causes and solutions are:

(1) Except for the same value set for two or more multi-function contact inputs, or "unused" and "external fault", the solution is to confirm whether there is any duplication of the function assigned to the multi-function contact access;

(2) the UP command and the DOWN command (10 and 11) are not set at the same time, or the UP2 command and the DOWN2 command (75 and 76) are not set at the same time, the operation command (2 limit sequential control 2) and the forward/reverse command 2 (2-wire sequential control 2) (42 and 43) are not set at the same time, or Drive Enable (6A) is assigned to both the multi-function input terminals S1 and S2, and the solution is to re-set the multi-function contact input, so that the functions used according to different combinations are assigned to both at the same time;

(3) Two or more of the following functions are set at the same time

(1) UP/DOWN Directives (10 and 11)

(2) UP2 and DOWN2 (75 and 76)

(3) Hold acceleration and deceleration stop (A)

(4) Analog Frequency Command Sampling/Holding (1E)

(5) Offset frequency □ superposition (□=1-3) (44-46)

The solution is to confirm whether the assignment cannot be made at the same time.

(4) When B5-01 (PI control selection) is valid, the UP/DOWN instructions (10 and 11) are set, and b5-01=0 (PI control is invalid), or the allocation of UP/DOWN instructions is canceled;

(5) The following functions that cannot be combined are assigned at the same time

(1) External Search Instruction 1 and External Search Instruction 2 (61 and 62)

(2) Emergency stop (normally open contact) and emergency stop (normally closed contact) (15 and 17)

(3) KEB (Slow Operation in the Event of Momentary Power Failure) Instructions 1 or 2 and HSB (High Slip Braking) ("65, 66, 7A, 7B" and "68")

(4) Motor switching command and acceleration and deceleration time selection 2 (16 and 1A)

(5) KEB Directive 1 and KEB Directive 2 ("65, 66" and "7A, 7B")

(6) Forward and reverse operation instructions (or reverse operation instructions) and operation instructions/forward and reverse instructions 2 (2 limit sequential control 2) ("40, 41" and "42, 43")

(7) External DB Directives and Drive Enable (60 and 6A)

(8) Motor switching command and UP2/DOWN2 command ("16" and "75, 76")

When H1-□□=2 (1/2 of the external command) is set, the following settings are also performed

(1) b1-15 = 4 (pulse train input) and H6-01 (pulse train input function) ≠0 (frequency command)

(2) B1-15=3 (Optional Card) or B1-16=3 (Optional Card) is set, but the Optional Card is not connected

(3) b1-15 = 1 (analog input), and H3-02, 10 (analog input function selection) = 0 (1st speed analog frequency command) are not set.

H1-□□=6A (Drive Enable) is not set, but H2-□□=38 (Drive Enable) is set.

H6-01=3 is not set (with PG control mode), but H1-□□=7E (direction of rotation is detected)

The solution is to confirm whether the function that cannot be combined is assigned, and reset the multi-function contact input;

(6) When assigning UP2/DOWN2 commands (75 and 76), a signed value (H3-01 or H3-09=1) is set for the multi-function analog input, and the solution is to cancel either of these settings.

(4) Operator display: oPE04

Fault Name: Terminal circuit board replacement detection

Reason: The main body of the inverter was replaced (the disassembled terminal strip with parameter backup function was not replaced) or the disassembled terminal strip with parameter backup was replaced, and the solution was:

(1) When setting the parameters stored in the detachable terminal strip with parameter backup function to active, set A1-03=5550 (oPE04 error reset)

(2) If you do not use the parameters stored in the detachable terminal strip with the parameter backup function, initialize the parameters (A1-02=2220 or 3330)

(5) Operator display: oPE05

Fault name: Improper selection of instructions, incorrect setting when executing operation instructions or frequency commands through communication card or pulse train input.

The causes and solutions are:

(1) Set b1-01 (frequency command selection 1) to 3 (optional card), but the input optional card is not connected on CN5-A, the solution is to connect the input optional card with the inverter;

(2) Set b1-02 (operation command selection 1) to 3 (optional card), but the input optional card is not connected on CN5-A, the solution is to connect the input optional card with the inverter;

(3) Set b1-01 (frequency command selection 1) to 4 (pulse train input), but set H6-01 to a value other than 0 (frequency instruction), the solution is to set H6-01 to 0;

(4) F3-01 (input selection for digital input cards) has been set to 6 (BCD special setting (5-bit input)), but F3-03 has been set to 0 (8 bit) or 1 (12 bit), and F3-03 has been set to 2 (16 bit);

(5) The following settings are also set, but the AI-A3 option is not connected

(1)B1-16 (Run Command Select 2) = 3 (Optional Card)

(2) H1-†† = 2 (Switch Command Right)

The solution is to set the parameters correctly;

(6) The following settings are also set, and the AI-A3 option is connected

(1) B1-15 (Frequency Command Option 2) = 3 (Optional Card)

(2) F2-01 (Analog input card action selection) = 0 (3 terminals input separately)

The solution is to set the parameters correctly.

(6) Operator display: oPE07

Fault Name: The multi-function analog input is not selected properly, and any of the functions of H3-02, H3-06, or H3-10 (multi-function analog input) is repeatedly selected, or the function assignment of the PI is duplicated

(1) If the same value is set for any 2 or more parameters in H3-02, H3-06, and H3-10, the solution is to reset it so that H3-02, H3-06, and H3-10 are not repeated. Note: H3-02, H3-06, and H3-10 can be set to 0 (1st speed analog frequency command) or F (reservation range) at the same time.

(2) The following settings are also set

(1) H3-02 or H3-10 = B (PI feedback)

(2) H6-01 (pulse train input function selection) = 1 (PI feedback value)

The solution is to cancel any of the PI function selections;

(3) The following settings are also set.

(1) H3-02 or H3-10= C (PI target)

(2) H6-01 (pulse train input function selection) = 2 (PI target value)

The solution is to cancel any of the PI function selections;

(4) The following settings are also set

(1) H3-02 or H3-10 = C (PI target)

(2) b5-18 (PI target value selection) = 1

(PI target for b5-19 is valid)

The solution is to cancel any of the PI function selections;

(5) The following settings are also set

(1) H6-01 = 2 or H3-10 = C (PI target)

(2) b5-18 = 1 (the PI target value of b5-19 is valid)

The workaround is to cancel any of the PI function selections.

(7) Operator display: oPE08

Fault Name: The parameter is inappropriately selected, and the function that cannot be used by the current control mode is set.

The causes and solutions are:

(1) In the non-PG V/f control mode, the function that is only used in the PM-free PG-free vector control is selected, and the solution is to recombine the control mode and the configurable function;

(2) In the PM with no PG vector control, n2-02 > n2-03 are set, and the solution is to reset the parameters to make n2-02 < n2-03;

(3) In the PM with no PG vector control, C4-02 > C4-06 ⇒ parameters are set to reset the parameters so that C4-02 < C4-06;

(4) In PM with no PG vector control mode, any set value in E5-02 - E5-07 is 0, and the solution is as follows

(1) Set E5-01 correctly according to the motor used (selection of motor code (for PM));

(2) When using a special motor, set the parameter E5-††□□ correctly according to the test report of the motor

(5) In the control mode with PG, b1-14 (phase sequence selection) = 1 (phase sequence reversal) is set, and the solution is to set the parameters correctly;

(6) In PM vector-free control mode, the following conditions overlap

　　①E5-03 ≠ 0

(2) Both E5-09 and E5-24 are 0 (or neither)

The solution is as follows:

(1) Set any parameter in E5-09 or E5-24 to the correct value. Set the other parameter to 0

(2) Set E5-03 (motor rated current (for PM)) to 0

(Note)

(1) Check which parameter in U1-18 (the parameter of oPE failure) is set improperly.

(2) When multiple errors occur at the same time, other oPE†† will be displayed before oPE08.

(8) Operator display: oPE09

Fault name: The PI control is not selected properly, and the function of the PI control is selected incorrectly (b5-01 (PI control selection) = 1-4).

The causes and solutions are:

(1) The following settings are also set.

(1) b5-15 (PI pause function action value) ≠ 0.0

(2) b1-03 (stop method selection) = 2 or 3 (DB stop or free run stop with timer)

Here's how to fix it:

(1) Set b5-15 to a value other than 0

(2) Set b1-03 = 0 or 1. (deceleration stop or free run stop);

(2) When b5-01 = 1 or 2 (PI2 point input), d2-02 (frequency command lower limit) ≠ 0 is set, and the solution is to set the parameters correctly;

(3) When b5-01 = 1 or 2 (PI2 point input), set b5-11 (PI output invert selection) = 1 (reverse when PI output is negative), and the solution is to set the parameters correctly;

(4) When b5-01 = 3 or 4 (PI3 point input), d2-02 ≠ 0 is set, and the solution is to set the parameters correctly.

(9) Operator display: oPE10

Fault Name: The V/f data is set incorrectly, and E1-04, E1-06, E1-07, E1-09, E1-11 (or E3-04, E3-06, E3-07, E3-09, E3-11) are set incorrectly.

The workaround is to reset parameters E1-04, E1-06, E1-07, E1-09, E1-11 (or E3-04, E3-06, E3-07, E3-09, E3-11).

(10) Operator display: oPE11

Fault name: The carrier frequency is set incorrectly, and the carrier frequency is set incorrectly.

The causes and solutions are:

(1) The following settings are also set

(1) C6-05 (proportional gain of carrier frequency) >6

(2) C6-04> C6-03 (lower limit of carrier frequency > upper limit of carrier frequency) (Note) C6-05≤6, operate according to the fixed value of C6-03

The solution is to set the parameters correctly;

(2) C6-02 - C6-05 upper and lower limits are set incorrectly, and the solution is to set the parameters correctly.

(11) Operator display: oPE13

Fault Name: Improper pulse train monitoring selection, H6-06 (pulse train monitoring selection) is set incorrectly.

The reason is that when H6-07 (Pulse Train Monitoring Ratio) = 0, the values other than the following 4 monitoring items are set in H6-06, 101, 102, 105, 116, and the solution is to reset H6-06 correctly.

(12) Operator display: oPE16

Fault name: The setting of energy-saving control parameters is improper, and the setting of energy-saving control parameters is incorrect.

The reason is that the set value of the energy-saving control parameter is outside the set range, and the solution is to confirm whether the value of the motor nameplate is consistent with the value of E5-□□.
