Parameter settings
P1-XX are the basic parameters
P1-00 pulse method selection, *** bit selection is 2, that is, pulse train + direction
P1-00 signal logic picking, the third digit is selected as 0 or 1, which is the positive logic or anti-logic, X0XX or X1XX
P1-01 Control form selection, select 0 is the direction control form
P1-32 The function of the motor abort form, set to 0 indicates that the abort method is immediately aborted
P1-37 The ratio of load inertia to the inertia of the motor itself is referred to as the inertia ratio, which is set to 10, and the inertia ratio is actively budgeted during commissioning
P1-44 electronic gear ratio numerator, set to 160
P1-45 Electronic gear denominator, set to 10
The ratio of P1-44 to P1-45 is 160:10
Check the manual and learn that the resolution of the encoder at the tail of the motor is 160000, and the resolution of the electronic gear ratio is 160000/1 turn, and the number of command pulses = P1-44/P1-45 = 160/10, then it can be known that the PLC sends 10000 pulses and the servo motor rotates once.
P2-XX are enlarged parameters
P2-08 Special parameter is written and set to 10, which means that the parameter is reset and the factory settings are restored.

The following DI and DO terminal functions can be set in the driver input DI and output DO function table for selection.
P2-10 Digital input pin DI1 function selection, set to 101, corresponding to servo on, normally open contact,
P2-11 Digital input pin DI2 function selection, set to 104, corresponding to clear pulse count CCRL, connected to normally open contact
P2-15 Digital input pin DI4 function selection, set to 022, corresponding to the reverse operation stop limit (b contact), connected to normally closed contact
P2-16 Digital input pin DI5 function selection, set to 023, corresponding to the forward operation stop limit (b contact), connected to normally closed contact
P2-17 Digital input pin DI6 function selection, set to 021, corresponding to the motor emergency stop (b contact), connected to normally closed contact
P2-18 Digital output pin DO1 function selection, set to 108, set the *** digital output as the electromagnetic brake signal, here you can refer to the driver output DO function table to explain, the motor with electromagnetic brake needs to turn on the enabling SON signal and the brake BRKR signal to rotate.
During debugging, P2-15 to P2-17 can be set to 0, which means that the forward and reverse limit and the urgent stop function are closed, and the driver has no forward and reverse limit and emergency stop alarm. When the driver is in normal use, the positive and negative limits and emergency stop functions are required to be turned on to play a certain protective effect.
Resonance press the setting of the parameters
P2-23 *** group mechanical resonance frequency set value (*** group mechanical resonance frequency set value, if P2-24 is set to 0, this function is closed. )
P2-25 resonance press low-pass filtering
P2-26 External Interference Resistance Buff
P2-47 Active resonance is set to 1, which means that it is actively fixed after vibration suppression
P2-49 Velocity Detection Filtering and Micro Vibration Pushing
After setting the above parameters, the active gain will begin
P2-32 Gain adjustment method selection, 0 is manual mode, 1 is active mode, 2 is semi-active mode. Set to 1 or 2, the servo estimates the value of the inertia ratio P1-37 every half an hour during operation, and then combines the rigidity and bandwidth settings of P2-31 to actively correct the values of P2-00, P2-04, P2-06, P2-25, P2-26, P2-49 and other parameters.
P2-33 Semi-active form inertia adjustment condition, when the condition is 1, the value budget of the inertia ratio P1-37 is completed, and the corresponding control parameter values are fixed. Set P2-32 to 0, and manual gain adjustment is also possible.
Practice produces true knowledge, and without practice, theory is just sitting and discussing; More tests and verifications are required in learning.
