DCS 600 Operating Instructions
Definition /
Possible source
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 43.11], and [P 43.12]
Alarm: Mains Undervoltage (AC)
Setting of undervoltage monitoring with Pa-
rameter or/and
[P 40.01]
Check: - See also Fault Code
Alarm: Armature Current Deviation
If the current reference ARM_CUR_REF
deviates from the current feedback
[P 3.12]
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
Alarm: Overtemperature MOTOR 2
Check: - Parameter setting
correct?
See also Fault Code
Alarm: Overload MOTOR 2 (Thermal Model 2)
Check: - Overload of motor
- Parameter setting
correct?
Alarm: No Acknowledge DC Break or Dyna-
mic Brake contactor
Check: - Digital inputs
Alarm: No (Thyristor Power) Converter FAN
