Characteristics/details Cause Remedy
MD: Incorrect power supply fre-
quency
▪ Event No. 1883
Incorrect power supply frequency Check the motor-drive unit power supply.
Power failure during switching

Power failure Determine the cause of the power failure.
MD: Voltage difference
▪ Event No. 1803
Difference in voltage between the
3 phases greater than 10V
Check the motor-drive unit power supply.
MD: Current difference

Characteristics/details Cause Remedy
MD interior temperature limit
value
▪ Event no. 1858, 1859, 1860 or
1861
The motor-drive unit interior tem-
perature is greater than the > limit
value.
Check the measured value for plausibility.
This event will be reset automatically once the
measured value is lower than the limit value
again.
The motor-drive unit interior tem-
perature is greater than the >> limit
value.
The motor-drive unit interior tem-
perature is less than the < limit
value.
Check the measured value for plausibility.
This event will be reset automatically once the
measured value is greater than the limit value
again.
The motor-drive unit interior tem-
perature is less than the << limit
value.
Configuration error Check the configuration of the analog input
[►Section 9.29, Page 292].
Check the limit value setting.
Wiring error Check wiring as per connection diagram.
▪ Sensor CT373, terminal X6.1:1/4
Sensor defective Replace sensor
MD interior temperature invalid
▪ Event No. 1325
Configuration error Check the configuration of the analog input
[►Section 9.29, Page 292].
Wiring error Check wiring as per connection diagram.
▪ Sensor CT373, terminal X6.1:1/4
Sensor defective Replace sensor
Sensor for MD interior tempera-
ture defective
▪ Event No. 1837
Sensor defective Replace sensor
