Possible cause and remedy
Ready for operation.
There is no drive enable signal present. There are no error messages present.
STO inputs (pin 3 and pin 4) 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 resistance value is not lower than the minimum
permissible braking resistance.
Thermal overload on brake resistor
The drive has been switched off in order to prevent the brake resistor from
being thermally destroyed.
• Extend the P1-04 and P2-13 ramp times to reduce the frequency of 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 inverter and 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 (P6-01 = 1): Check whether the value cos ϕ (P7-02) 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 (P6-01 = 6): Reduce the voltage boost using 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.
Motor overload. The thermal protection mechanism has tripped as a result of
the device being run above the motor nom current set with P1-08 longer than
a specific time.
• Check to make sure that the motor data was entered correctly in P1-07,
P1-08, and P1-09.
• In vector mode (P6-01 = 1): Check whether the value cos ϕ (P7-02) has been
entered correctly and a motor identification run has been successfully
performed.
• Check the motor's connection configuration (e.g., start/delta)
• If the decimal points on the display flash during operation, this means that
the unit is being run in its overload range (> P1-08).
In this case, use P1-03 to make the acceleration ramp longer or reduce the
load.
• Make sure that the motor is not being mechanically blocked and that there
are no additional loads on the motor.
