Possible cause and remedy
Ready to start. There is no drive enable signal present. There is no error
message present.
STO inputs (terminals 12 and/or 13) de-energized
• Safety relay switched off
• Voltage source overloaded
Consequence: The drive is disabled.
Shown for P0-13 if there are no messages in the error register.
Excessively high braking current
• Check the brake resistor and its wiring for short-circuits and ground faults.
• Make sure that the braking resistor value is not lower than the minimum
permissible braking resistor value.
Thermal overload on brake resistor
The drive has been switched off in order to prevent the brake resistor from
being thermally destroyed.
• Make the P1-04 and P2-25 ramp times longer in order to have less frequent
braking.
• Reduce the load's inertia, if possible.
Overcurrent at variable frequency drive output
Occurs right after switching on the unit:
• Check the cable connection between the inverter and the motor.
• Check the motor for shorted turns and ground faults.
Occurs when starting the motor:
• Check whether the motor can rotate freely and make sure that it is not
being blocked mechanically.
• Motor with mechanical brake: Check whether this has been triggered.
• Check the connection configuration (star/delta).
• Check to make sure that the motor data was entered correctly in P1-07,
P1-08, and P1-09.
• In vector mode (P4-01 = 0 or 1): Check whether the value cos ϕ (P4-05) has
been entered correctly and a motor identification run has been successfully
performed.
• Increase the acceleration ramp time (t-acc, P1-03) if necessary.
• With speed control (P4-01 = 2): Reduce the voltage boost with P1-11.
Occurs during operation at a constant speed:
• Check whether the motor is overloaded.
Occurs during acceleration/deceleration:
• The ramp times are too short and require too much power.
If P-03 / P-04 cannot be increased, a larger device may be required.
