Schneider touch screen touch deviation causes

　Debugging parameters: ​ 1. Acceleration and deceleration time Speed up the time setting requirements: the acceleration current is constrained below the overcurrent capacity of the inverter, so that the overflow will not cause the inverter to trip; Deceleration time setting key ...

The troubleshooting method of the electrical control line is not the same as a thousand people, and various methods can be used cooperatively, but do not copy the rigid set. In general, investigative research can help us to find out the problem. The experimental method can not only find out the fault phenomenon, but also find the fault location or fault circuit; Logic...

Rotary encoder to roll the output pulse, through the counting equipment to know its position (PLC) we usually use incremental encoders, the incremental encoder output pulse signal can be directly input to the PLC, the high-speed counter of the PLC to count its pulse signal, in order to obtain the ...

1. Qualified after inspection When selecting a double fan inverter, it must be strictly checked for its quality. The first requirement is that it must have relevant certificates of qualified inspection, and some qualified materials must be taken out. This is the only way to ensure that this change ...

The unreliable contact touch will increase the touch resistance between the dynamic and static contacts, resulting in the high temperature of the touch surface, making the surface touch become a point touch, and even showing a non-conduction phenomenon. The reasons for this failure are: (1) There are ...

(1) Add inductance and capacitance on the input side of Schneider inverter to form an LC filtering network (2) The power cord of the Schneider inverter is supplied directly from the transformer side. (3) If conditions permit, a separate ...

According to the statistical analysis of the frequency and shutdown time of the specific common problems of the inverter, the repair rate of the main power supply circuit accounts for more than 60%; The main operating parameters are set improperly, resulting in about 20% of common problems; 15% of the common problems of manipulating circuit boards; 5% of common problems are caused by incorrect operation and external anomalies ...

1. Overload maintenance failure: The circuit breaker should be tripped for maintenance when the current exceeds the rated current, but sometimes the overload maintenance failure may be due to some reasons. This may be due to incorrect overload maintenance settings, long overload periods, thermal aging due to successive overloads, etc. 2 ...

What is the difference and contact between the instrument, external work verification, calibration, and calibration? Verification, calibration, and calibration are all static measurement processes that are carried out in cycles. The meanings are: The verification ---- shall be arranged by the legal metrology department or the statutory authorization in accordance with the verification procedures, after ...

UPS power supply is widely used in shopping malls, supermarkets, banks and other enterprises and institutions, the primary effect of the power supply is to provide continuous power supply for the unit in the state of power failure, so as to ensure the normal operation of the computer network system and other application systems, and effectively avoid data loss. In the power supply ...

(1) It is necessary to choose a four-pole switch: For the sake of repair safety: in the TT grounding system, the total equipotential bonding is done on the user side, but because the total equipotential bonding at this moment does not include the neutral wire, the line fault (for example: a phase wire grounding) occurs on the grounding electrode on the power supply side.

1. Don't blindly knock and bump when overhauling to avoid expansion failures, and the more you repair, the worse it gets. 2. Do not plug and unplug various control boards and plugs with electricity. Due to the strong induced electromotive force generated by plugging and unplugging the control board under the power-on condition, the instantaneous ...

1. Use the analog output port to indicate the motor frequency, when the motor frequency is 50Hz, why is the output only 16mA? Because the maximum output frequency parameter of the inverter is "TFR", the factory default value is 60Hz. So when the inverter output is 50Hz, the analog output is 16mA. At this time, only ...

Schneider RSL Thin Sheet Relay, as a member of the large family of ZelioRelay series relays, RSL Thin Plate Relays will be committed to saving users space and time in the device, and improving the stability of the system. Schneider Electric Vice President of China, Head of Industrial Division, Xiu De...

Because the impact of foreign electrical products on domestic electrical equipment is relatively large, now Schneider inverter equipment occupation is facing a big technical promotion, taking inverter as an example, the national connotation of inverter shopping mall domestic brand and foreign brand, regardless of technology, processing and manufacturing, industrial design and other aspects are still ...

1. After the inverter is repaired, the power number demand is corrected, don't forget Generally, an inverter corresponds to a power number (also known as the number of horsepower), for example, a 75 kilowatt inverter is set under heavy load, and 100 kilowatts is set under light load. In this way, the customer will not use it to present ...

a. Output frequency scale. The output frequency scale that can be controlled by the general inverter, the lowest starting frequency is generally 0.1Hz, and the highest frequency varies according to the functional indicators of the inverter, generally 400Hz, and some models are 650Hz. No matter how high the output frequency is, it depends on the scale of the high-frequency inverter. ...

ATS48 soft starter is used in water treatment, food and beverage, mining metallurgy, power and chemicals. Scope of application: including pump fans and large inertia machine compressor conveyors Advantages: 1. Economical solution Reduce mechanical stress and increase machine availability. 2. ...

1. After the UPS power supply is shut down, the output terminal is still powered, but the UPS power supply does not play a role at this time, and it is in a bypass state. 2. The power supply will not be cut off after the UPS power supply is shut down, because the UPS power supply will go bypass after the shutdown, there is still a mains power input at this time, ...

1 Contingency plan Contingency plans are the top priority of preventive protection. Arrangements need to be better partnered with service providers to be part of the corporate programme. This means implementing processes and procedures for every type of thing, including contingency plans. ...
