2205
• Faulty motor, motor cables or connections.
Over voltage controller is active. Check for and correct:
OVERVOLTAGE
• Static or transient overvoltages in the input power supply.
• Insufficient deceleration time (parameters 2203
2206
Under voltage controller is active. Check for and correct:
UNDERVOLTAGE
• Undervoltage on mains.
The change in direction being attempted is not allowed. Either:
DIR LOCK
• Do not attempt to change the direction of motor rotation, or
• Change parameter 1003
reverse operation is safe).
/ Fieldbus communication has timed out. Check for and correct:
