Monitoring functions

Motor temperature The temperature limit values are pre–assigned, corresponding to the
monitoring selected motor when the motor code is specified; the user should not
change these.
The following motor temperature monitoring functions are available:
S
S
Note
The temperature monitoring functions (warning P1602 + timer P1603
or P1607) are not subject to any mutual restrictions, i.e. it is
permissible that P1607 < P1602.
S
Note
The temperature monitoring functions of the motor, set using P1602 or
P1607, are then no longer effective.

6.1 Operating mode, speed/torque setpoint (P0700 = 1)
Temperature monitoring with pre–warning (P1602 + P1603)
If the temperature warning threshold (P1602) is exceeded, the result
is as follows:
– Warning 814 is output
– Timer (P1603) is started
– Motor overtemperature is signaled via terminal 5.x at the NE
module
Note:
This signal is saved, if it is still present after the time in P1603
has expired.
– The "motor temperature pre–warning" (MeldW.6) output signal is
set
If the overtemperature condition still remains after the time set in
P1603, then this results in fault 614 and the drive is powered down.
The monitoring function can be enabled/disabled using P1601.14.
Temperature monitoring without pre–warning (P1607)
If the temperature threshold in P1607 is exceeded, this immediately
results in fault 613 and the drive is powered down.
The monitoring function can be enabled/disabled using P1601.13.
Specifying a fixed temperature (P1608)
When a fixed temperature is specified, the temperature–dependent
adaptation of the rotor resistance is executed with this fixed temper-
ature.
