Alarm
No.
A032 SIMOREG CCP not ready
(active in operating states of < o4.0)
Possible causes
•
No voltage at U, V, W terminals of SIMOREG CCP
•
Voltage at C-D on CCP does not match voltage at C-D on SIMOREG DC master
•
Surge absorbing capacitors of SIMOREG CCP have not reached setpoint voltage
•
Paralleling interface cable is not connected to SIMOREG CCP assigned to paralleling master
•
No connection between SIMOREG DC master and SIMOREG CCP via G-SST2 serial interface
•
No connection between parallel SIMIOREG CCPs
•
Contents of technical data memory on SIMOREG CCP (MLFB, rated values, serial number) invalid
•
I2t value of voltage chopper 1 is too high (> 100%)
•
I2t value of voltage chopper 2 is too high (> 50%)
A033 Alarm message from free function block FB8
(active in all operating states)
The binector connected via parameter U106 Index.001 is in the log. "1" state
A034 Alarm message from free function block FB9
(active in all operating states)
The binector connected via parameter U107 Index.001 is in the log. "1" state
A035 Drive blocked
(active in operating states of – –, I, II)
The monitoring function responds if the following conditions are fulfilled for longer than the time set in parameter P355:
♦ Positive or negative torque or armature current limit reached
♦ Armature current is greater than 1% of converter rated armature DC current
♦ The actual speed value is less than 0.4% of maximum speed
A036 No armature current can flow
(active in operating states of – –, I, II)
This monitoring function responds if the armature firing angle is at the rectifier stability limit for more than 500 ms and the
armature current is less than 1% of the converter rated armature DC current.
I 2 t motor monitor has responded
A037
(active in operating states of – –, I, II)
The alarm is activated when the calculated I 2 t value of the motor reaches the value which corresponds to the final temperature
at 100% of permissible continuous motor current (= P113*P100).
A038 Overspeed
(active in operating states of – –, I, II)
The monitoring function responds if the actual speed value (selected in P595) exceeds the positive (P512) or negative (P513)
threshold by 0.5%.
Possible causes
♦ Lower current limit has been input
♦ Current-controlled operation
♦ P512, P513 are set too low
♦ Tachometer cable contact fault in operation close to maximum speed
I 2 t value of power section too high
A039
(active in all operating states)
This alarm is activated if the permissible I 2 t value for the relevant power section is reached. At the same time, the current limit is
set to P077 * 100% of the converter rated DC current. This limit is not cancelled again until the setpoint drops below 100% of the
converter rated DC current. See also Fault F039 and Parameter P075.
A043 Automatic field current reduction if EMF is too high in operation
(active in operating states of – –, I, II)
This alarm is active only when parameter P272=1 and activated if the following equation applies to firing angle α (armature)
before limitation (K101):
α > (α W (inverter stability limit acc. to P151) – 5 degrees) or , at a low (pulsating) current
α > (165 degrees – 5 degrees)
AND armature current setpoint K0118 filtered with P190.F is > 1% of r072.002
The field is reduced simultaneously with A043, implemented through control of the armature firing angle to (α W (or 165 degrees)
- 5 degrees) using a P controller whose output reduces the EMF controller setpoint. For this reason, "Field weakening operation
through internal EMF control" (PO81=1) must be parameterized.
When a change in torque direction is requested, both torque directions are inhibited until the calculated control angle (K101) is
<165 degrees for the armature current requested in the new torque direction, i.e. until the field, and thus the EMF, have been
reduced accordingly.
See also parameter P082.
