Number / Alarm Cause Counter-measure
A018
Encoder adjustment
Signal amplitude resolver/encoder in critical
range
Resolver/encoder in the critical range.
See F051 for causes/counter-measures.
As a general rule, it is necessary to initialize
the starting position again => power OFF/ON
or switch to the drive settings and back
again!!!
If alarm A18 occurs in the"Ready" status (r001
= 009) while an encoder is in use, the
amplitude of the CD track signal is too small,
or the connection to CD_Track may be
interrupted, or an encoder without CD-Track is
in use.
In the case of an encoder without CD track,
the P130 must be correctly set.
A019
Encoder data serial
protocol
Connection fault of the serial protocol on
multiturn encoders (SSI/Endat)
Serial protocol is defective on multiturn
encoders. See F051 for causes/counter-
measures.
As a general rule, it is necessary to initialize
the starting position again => power OFF/ON
or switch to the drive settings and back
again!!!
A020
Encoder adjustment,
external encoder
The amplitude of an external encoder lies in
the critical range.
Cause/remedies see F051
As a general rule, it is necessary to initialize
the starting position again => power OFF/ON
or switch to the drive settings and back
again!!!
A021
Encoder data of
external multiturn
encoder faulty
A fault has occurred during processing of the
serial protocol to an external code rotary
encoder (SSI- or Endat-Multiturn).
Faulty serial protocol in the case of an external
multiturn encoder. Cause/remedies see F051
As a general rule, it is necessary to initialize
the starting position again => power OFF/ON
or switch to the drive settings and back again!!
A022
Inverter temperature
The threshold for tripping an alarm has been
exceeded.
- Measure intake air and ambient temperature.
- Observe derating curves at theta > 50°C
(Compact PLUS) or 40°C
- Check whether the fan is operating
- Check whether the air entry and discharge
openings are restricted.
A023
Motor temperature
The parameterizable threshold (P380) for
tripping an alarm has been exceeded.
Check the motor (load, ventilation, etc.). Read
off the current temperature in r009 Motor
Temperat.
A025
I2t converter
If the current load state is maintained, a
thermal overload of the converter occurs.
The converter will lower the max. current limit
(P129).
- Reduce converter load
- Check r010 (Drive Utiliz)
A029
I2t motor
The parameterized limit value for the I2t
monitoring of the motor has been exceeded.
Motor load cycle is exceeded!
Check the parameters:
P382 Motor Cooling
P383 Mot Tmp T1
P384 Mot Load Limits
A033
Overspeed
The positive or negative maximum speed has
been exceeded.
- Increase relevant maximum speed
- Reduce regenerative load (see FD 480)
