Hi,
I have:
Sigma Drive Controller PMT835M
Lemco motor LEM-200-D127 DC1
Albright 72 v contactor

Need your help please.

Motor is running, But just forward. If i switch to reverse (switch) the status display goes from „neutr“ to „Dbrake“...
Tthe seller told me the Motor should easily turn reverse when i install a switch (no extra changeover contactor needed).

Found in manual Dbrake stands for regenerating braking.
But why when I switch to reverse direction? I want to go reverse…

thanks for your help

gerri

Check for voltage at pin 2 (reverse signal)of the A plug and no voltage at Pin 1(forward)

if you are also using external contactors for forward and reverse the normally closed position needs to be checked for continuity.
