I need technical support for running this VFD from PLC S7 1200. 1) Terminals for Analog frequency command? 2) Parameters to enable switching between Jog/Remote Mode 3) above 2 points are enough ? Or I have to give Digital start command along with analog reference too? Pls help me with complete procedure to RUN this VFD from PLC.. I am only looking for knowing things about drive and its requirements. I know how to configure from PLC accordingly . Thanks Gajendra D S

Normally you need one analogue signal in case you need to change the speed. It depends if you want to run the VLT in Jog mode. Then you need a start signal from the plc, normally a feed back (fault/running) from VLT to plc and maybe a reset signal from plc to VLT. Scott

	Regards, Jacek What is confusing you is the fact that you never see a number but always its digit representation. So you end up thinking that the number is the representation. - Andrej Bauer Any claims against me - based on whatever legal reason - resulting from the use of any code and/or ideas presented on this forum shall be excluded. #StayWithUkraine
