Issue with Man Roland 300 - Main Drive Not Working

[alrasby]

Hello, we have a problem with the Man Roland 304P press. We recently bought the machine from Europe. When the device is started using the main switch, the machine starts loading the software. The air supply will also start, but the main drive will not.
I am attaching a screenshot of the errors to the current problem. I would appreciate any advice on solving the problem.

Hi sir;
Problem:
• No machine run possible
or
• Error message on the Leitstand : “SPS: HA: brake does not release“
!
Check following voltages:

1. armature voltage

2. field voltage

3. field current

See his schematic diagrams electrical
