PFCL201C 10KN D/A Conversion Module

PFCL201C 10KN through the D / A conversion module issued to control the speed of the frequency converter speed command so that each frequency converter speed control drive motor according to a certain speed ratio. This program for the number of motors, motor distribution is more centralized application system is more appropriate. But for mass production automatic line, on the one hand, the number of motors, on the other hand, the motor distribution distance is far.

When PFCL201C 10KN adopts this control scheme, due to the attenuation of the speed command signal in long-distance transmission and external interference, the stability and reliability of the whole system will be reduced; at the same time, a large number of D/A converter modules will increase the cost of the system. For this reason, we propose a PLC and frequency converter governor constitute a multi-branch communication control network. The system has low cost, long signal transmission distance, strong anti-interference ability, especially suitable for long-distance, multi-motor control.
