15 CURR RIPP
Armature current ripple
One or several thyristors carry no current.
Check: - Current feedback with oscilloscope
(6 pulses within one cycle visible?);
- Branch fuses, thyristor gate con-
nection and gate-cathode resis-
tance;
- See also parameters
[P 43.10],
[P 43.11], and [P 43.12]
9.05 bit 0
A 118
18 MAIN UVLT
Alarm: Mains Undervoltage (AC)
Setting of undervoltage monitoring with Pa-
rameter
[P 40.01] or/and [P 40.02]
Check: - See also Fault Code F 29.
9.04 bit 10
A 120
20 CURR DEV
Alarm: Armature Current Deviation
If the current reference ARM_CUR_REF
[P 3.12] deviates from the current feedback
for more than 5 sec by more than 20 %,
referenced to the rated current, this signal
will be shown.
Check: - Ratio between mains supply
voltage and EMF

23 MOT2 TEMP
Alarm: Overtemperature MOTOR 2
Check: - Parameter setting [P 28.13]
correct?

A 124 24 MOT2 LOAD
Alarm: Overload MOTOR 2 (Thermal Model 2)
Check: - Overload of motor
- Parameter setting
[P 28.07]
correct?
9.04 bit 9
A 125
25 NO ACK
Alarm: No Acknowledge DC Break or Dyna-
mic Brake contactor
Check: - Digital inputs [P 15.18], [P 15.20]
