Hi engineers I faced an issue working with V20 drives. I need to synchronize 2 drive motors together and to do this one of them takes command from PLC using modbus RTU which there is no problem with that, and the other drive motor is taking command from the first one using analog input; So I need to assign frequency setpoint on analog input1 (P1000=2) and the type of signal is 0~20mA. there exists an offset on setpoint frequency both in possitive and negetive frequencies and also when I apply 0mA to analog IN1. but in full scale setpoint (50.00Hz) when I apply 20mA , 50.00Hz is applied with no problem. There is also a video attached.Analog input is set on 0~20mA and P0758=-100, I set 12.5Hz (12.5mA) and the setpoint on drive varies from 12.27Hz to 12.40Hz. Im very thankful if anybody can help me with this issue. Regards AttachmentV20 Analog IN Issue (video-converter.com).mpg (708 Downloads) |
