The motor temperature is monitored by a temperature sensor and a
temperature model. As soon as the maximum allowed motor temperature
(
S-0-0201, Motor warning temperature
) has been reached, the warning
E2051 Motor overtemp. prewarning
is output for 30 s. The drive is then
switched off by the error
F2019 Motor overtemperature shutdown
being triggered.
Note:
In the case of MHD, MKD, MKE and LSF motors, the motor
overtemperature prewarning cannot be used due to the
temperature sensor characteristic!
For MSK and MLF motors the prewarning function can be
used because an appropriate temperature sensor is used for
these motors.
Cause
Remedy
S-0-0201, Motor warning temperature
incorrectly
parameterized
Check and correct parameterization of
S-0-0201, Motor
warning temperature
by means of motor or
temperature sensor data sheet
The motor is overloaded. Effective torque demanded
by the motor was above allowed torque for a too long
time
Check motor dimensioning and reduce motor load, e.g.
by reduced infeed velocity in the case of metal-cutting
machining. In the case of installations that have been
operated for a long time, check whether drive conditions
have changed (with regard to dirt accumulation, friction,
moved masses etc.).
Line interruption, ground fault or short circuit in line
for motor temperature monitoring
Check line for motor temperature monitoring for line
interruption, ground fault or short circuit
Instability in speed control loop
Check parameterization of speed control loop
