Hi,
I'm stumped with this. I'm attempting to perform some positioning using a Powerflex 755 series VFD. First time I've done something like this.
My first issue is homing. I cannot get it to work. By triggering the required bits in the HomingControl register I get the drive into homing mode and the motor runs as expected and hunts but doesn't do anything when the Homing input (wired to UFB card) on the drive is detected.
This homing I have been trying with the Feedback selected to open loop. This i only discovered tonight using the Drive Homing wizard. If change it to Port 5 Param FB1 Position which is where the encoder is attached then the motor starts to vibrate and nothing happens.
Anyone done this before? There are so many parameters in this drive and whilst I've used many times its a different beast in positioning mode.
Any tips appreciated.
