Hi,
the pcb´s seem to be the same.
i'll send you a link with documents i have.
Please do the commissioning troubleshooting according to the manual if necessary.
Version of Invmon ?
What happens when you install the new PCB in the PS1?
The same fault as PS2?
Do PS1 and PS2 MCB PCB's have the same software H12?
To troubleshoot increase reg_fault_delay.
Is the motor energized when the startup starts, how much current does the motor consume?
Is the brake signal on?
Disable "speedo supervision" jumper, same fault?
