Mirager44 Posts: 2 Rating: (0)	I own your Simens Sinamics v20 frequency converter of 0.75kW and I have a problem with the connection I can not set the inverter to control it with external potentiometer and external switch for start and end of motor rotation. My desire is to set the desired engine speed with the external potentiometer and then start the engine with an on / off switch. I have not been able to get together any of the settings I used. Please help in configuring and connecting the external wiring of the frequency converter Nice regards ------------------------------------------------------------------------------------------ Split from Sinamics V20.

Mirager44 Posts: 2 Rating: (0)	I solved some of the problem I use the macro to connect cn002 finally i got instructions that i need a potentiometer of 5kΩ for the manual setting of the motor speed. There are two problems when I set the speed and the motor startup contact is turned on the frequency motor at least 10 Hz higher than the potentiometer I set? The other problem is that even though I set the input ramp p 1020 to (150.00) the engine spins immediately at the set speed i do not know why this is happening. When I switch the inverter to HAND or JOG mode then the input and output ramps work as I have set it up? I no longer know how to solve this problem.I've been trying to contact Simmens office in our country and all I got is localized instructions.
