Posted 24 Sep 2014 Hello guys, i would like to know if is possible keep always active the run command in a vf drive and for stopping the motor only send 0 reference. It´s possible??? because I want to program a ramp function in my plc for start and stop one motor. could someone tell me how to do this type of control please?.

Posted 25 Sep 2014 Yes, this is possible, if OK from the safety point of view. The drive may need to be configured for so called direct start (the terminology may differ among the brands), otherwise always active run command may cause an error on the drive power up.

Posted 25 Sep 2014 Depends on the PLC and the drive. You didn't specify which on either one. Please be more specific so we can provide more accurate answers. Share this post Link to post Share on other sites
