Number / Fault Cause Counter-measure
F015
Motor blocked
Motor is blocked/overloaded (current control),
or has stalled (v/f characteristic):
Static load is too high
The fault is not generated until after the time
entered in P805.
Binector B0156 is set, in status word 2 r553 Bit
28.
Whether the drive is blocked or not can be
detected at P792 (Perm Deviation) and P794.
P806 enables detection to be limited to "at
standstill" (P806 = 1, only for current control)
or to be completely de-activated (P806 = 2).
In the case of current control, the precondition
for this fault is that the torque limits (B0234)
have been reached.
In the case of slave drive, detection is de-
activated.
In the case of v/f control, the I(max) controller
must be active.
- Reduce the load
- Release the brake
- Increase current limits
- Increase P805 Blocking Time
- Increase the response threshold for the
permissible deviation P792
- Increase torque limits or torque setpoint
v/f characteristic only:
- Reduce rate of acceleration
- Check characteristic setting.
F017
SAFE OFF
SAFE OFF operating or failure of the 24 V
power supply during operation (only for
Compact PLUS units)
Jumper applied for SAFE OFF?
SAFE OFF checkback connected?
On Compact PLUS units: check 24 V supply
F020
Excess temperature of
motor
The motor temperature limit value has been
exceeded.
r949 = 1 Motor temperature limit value
exceeded
r949 = 2 Short-circuit in the motor temperature
sensor cable or sensor defective
r949 = 4 Wire break of motor temperature
sensor cable or sensor defective
- Temperature threshold adjustable in P381!
- P131 = 0 -> fault de-activated
- Check the motor (load, ventilation etc.)
- The current motor temperature can be read
in r009 (Motor Temperat.)
- Check the sensor for cable break, short-
circuit
F021
Motor I2t
Parameterized limit value of the I2t monitoring
for the motor (P384.002) has been exceeded
Check: Thermal time constant of motor P383
Mot ThermT-Const or motor I2t load limit
P384.002.
The I2t monitoring for the motor is
automatically activated if P383 >=100s
(=factory setting) and P381 > 220°C is set.
Monitoring can be switched off by setting a
value <100s in P383.
F023
Excess temperature of
inverter
The limit value of the inverter temperature has
been exceeded
- Measure the air intake and ambient
temperature.
- Observe the derating curves at theta > 50 °C
(Compact PLUS) or 40 °C
- Check whether the fan is running
- Check that the air entry and discharge
openings are not restricted
F025
UCE upper switch/UCE
Phase L1
UCE upper switch (Compact PLUS) / UCE
Phase L1 (chassis-type unit)
- Check the converter outputs for earth fault
- Check the switch for "Safe OFF" on Compact
units
F026
UCE lower switch/UCE
Phase L2
UCE lower switch (Compact PLUS) / UCE
Phase L2 (Compact, chassis)
- Check the converter outputs for earth fault
- Check the switch for "Safe OFF" on Compact
units
