705 Motor temperature for characteristic
curve of ASM slip invalid, lower than -
50°C or higher than 200°C
The motor temperature that is measured via the KTY encoder is
monitored for asynchronous motors due to slip characteristic curves
If the temperature is lower than -50°C or higher than 200°C, the tem
-
perature values are assumed to be invalid and the error will be trig-
gered.
m Cause:
The KTY motor temperature encoder was incorrectly connected
or not at all connected.
n Remedy through:
n Check connections and cable of KTY motor temperature
encoder.
n Monitoring may be deactivated for intended operation without
temperature encoder.
m Cause:
KTY motor temperature encoder defective.
n Remedy through:
n A defective KTY motor temperature encoder generally requires
motor replacement.
n Monitoring may be deactivated for intended operation without
temperature encoder.
m Cause:
Evaluation switch of the KTY motor temperature encoder in the
drive controller is defective.
n Remedy through:
n Drive controller replacement.
n Monitoring may be deactivated for intended operation without
temperature encoder.

717 Excess voltage occurred during resis-
tance measurement
Error during identification of motor parameters. The maximum per-
mitted phase voltage (= 80 V) was exceeded during the resistance
measurement.
m Possible cause:
Incorrect motor nominal current setting in Parameter 107.09.
Pulse block
718 Voltage limit accessed during resis-
tance measurement
Error during identification of motor parameters. The voltage limit was
reached during the resistance measurement.
m Possible causes:
Incorrect motor nominal current setting in Parameter 107.09.
