accelerating because of the load.
Verify speed limits.
F50 PSU FAULT
Damaged power supply.
Reset the equipment and if the fault persists
request technical assistance.
F51 SCR TEMP
Temperature limits for SD700 rectifier have been
exceeded.
Verify that the ambient conditions are proper for
the equipment.
