F60137 (N, A)
I2t monitoring fault excessive motor temperature rise
Message value:
-
Message class:
Motor overload (8)
Drive object:
DC_CTRL
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The I2t calculation shows that the motor's temperature rise is excessive.
The fault is triggered if the calculated motor temperature rise in r52309 > 110%.
Note:
r50047[1]: Temperature rise r52309
r50047[2]: Motor rated armature current p50100
r50047[3]: Continuous current factor r50113
r50047[4]: Device rated current r50072[1]
r50047[5]: Current armature current r52109
r50047[6]: Motor thermal time constant p50114
See also: p50114 (Motor thermal time constant), r52309 (Calculated motor temperature rise)
Remedy:
- Check the ambient temperature and reduce if necessary.
- Reduce the motor load.

F60139 (N, A)
I2t monitoring fault excessive power unit temperature rise
Message value:
-
Message class:
Overtemperature of the electronic components (6)
Drive object:
DC_CTRL
Reaction:
OFF2 (NONE, OFF1, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The temperature rise of the thyristors is more than 102 % of the maximum permissible value.
Remedy:
- Check the ambient temperature and reduce if necessary.
- Check the motor load and reduce if necessary.

A60143 (F, N)
Reduction of the field current setpoint for an excessively high EMF during braking
active
Message value:
-
Message class:
Motor overload (8)
Drive object:
DC_CTRL
Reaction:
NONE
Acknowledge:
NONE
Cause:
Reduction of the field current setpoint for an excessively high EMF during braking is active.
See also: p50272 (Field current reduction activation)
Remedy:
Not necessary.
The alarm automatically disappears after braking has expired.
Reaction upon F:
NONE (OFF2)
Acknowl. upon F:
IMMEDIATELY
Reaction upon N:
NONE
Acknowl. upon N:
NONE
