12.3 RASP Error list
Table 49: RASP Fault messages list
Message Error no. Possible cause and remedy
Stop
– Ready for operation. There is no drive enable signal present. There are no error
messages present.
Inhibt
– STO inputs (terminals 3 and 4) de-energized
• Safety relay switched off
• Voltage source overloaded
Consequence: The drive is disabled.
no-F

t
00 Shown for P0-13 if there are no messages in the error register.
OI-b
01 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.
OL-br
02 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 P2-13 ramp times longer in order to have less frequent
braking.
• Reduce the load's inertia, if possible.
O-I
03 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 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.
I.t-trP
04 Motor overload. The thermal protection mechanism has tripped as a result of
the device being run above the rated motor 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.
