ABB PU516 高速脉冲单元模块 应查看步进电机的绝缘，最好在接线之前完成对电机的单体调试查看，当电机契合现行标准要求时，再接外部线。一般低压电机的绝缘电阻要求大于0.5MΩ，摇表使用500V。但是，直流电机的励磁绕组和电枢绕组如果彼此直接反，就可能使电机电枢带电时，励磁绕组不带电而失磁，使电机空载时可能飞车，重载时烧坏转子。因而，直流电机的电枢绕组和励磁绕组的外部接线肯定不可彼此直接错。电机的外接线。电机接外部电线之前，应先查看端盖内的各个绕组引出端是否有松动现象，当内部引出线的压接螺丝上紧之后，才干按要求的接线办法连接短路片，并压接外部线。

步进电机在试运转时，要监视电机的电流是否超越规定值，并作记载。别的，还应查看下列项目：电机的旋转方向是否契合要求。沟通电机反向时，任意交换两根电机接线即可；直流电机反向时，能够交换两根电枢电压接线，也可改动两根励磁电压接线。电机运转的声响契合要求，即无冲突声、尖叫声、卡碰声及其他不正常的声响，否则应停机查看。即每个刀开关、空气开关、接触器、熔断器和热继电器，配电柜端子排的各个上、下接点及电机接线均要压接牢靠，才干确保电机牢靠安全运转，否则，就有烧坏电机的风险。

ABB PU516 high-speed pulse unit module should check the insulation of the stepper motor. It is best to complete the individual debugging and inspection of the motor before wiring. When the motor meets the current standard requirements, external wires should be connected. The insulation resistance of general low-voltage motors is required to be greater than 0.5M Ω, and the megger should use 500V. However, if the excitation winding and armature winding of a DC motor are directly opposite to each other, it may cause the excitation winding to lose excitation when the motor armature is energized, which may cause the motor to spin when unloaded and burn out the rotor when overloaded. Therefore, the external wiring of the armature winding and excitation winding of a DC motor must not be directly wrong with each other. External wiring of the motor. Before connecting the motor to external wires, it is necessary to check whether there is any looseness at the outgoing terminals of each winding inside the end cover. Only after the crimping screws of the internal outgoing wires are tightened can the short circuit strips be connected according to the required wiring method and the external wires be crimped.

After the completion of the ABB PU516 high-speed pulse unit module motor device and wiring, and before the motor test run, the engineer hereby suggests that the customer should mainly conduct the following checks: the civil cleaning and organization are completed; Motor monomer device, inspection completed; The debugging of the motor control circuit and other secondary circuits has been completed and the operation is normal; When moving the motor rotor, it should rotate sensitively and have no collision or jamming phenomenon; All wiring of the main circuit system of the motor is firmly fixed without any looseness; Other subsidiary systems are complete and qualified. The installation electrician should pay special attention to Article 5. The main circuit system mentioned here refers to all main circuit wiring from the power input of the power distribution cabinet to the motor terminal, which must be firmly connected.

During the trial operation of the stepper motor, it is necessary to monitor whether the current of the motor exceeds the specified value and record it. In addition, the following items should also be checked: whether the rotation direction of the motor meets the requirements. When communicating with the motor in the opposite direction, simply exchange the wiring of any two motors; When a DC motor is in reverse, it is possible to exchange two armature voltage connections or modify two excitation voltage connections. The sound of the motor operation meets the requirements, i.e. there are no conflicting sounds, screams, jamming sounds, or other abnormal sounds. Otherwise, the machine should be shut down for inspection. Each knife switch, air switch, contactor, fuse, and thermal relay, as well as the upper and lower contacts of the distribution cabinet terminal block and motor wiring, must be firmly crimped to ensure the reliable and safe operation of the motor. Otherwise, there is a risk of burning the motor.
