3. Controller Functions
3.11 Temperature Pre-Warning
Due to the overload capacity of the main drives, load cycles can be used
which need more than the continuous power from the drive for short
periods. Choice of correct drive size ensures that the temperature of
motor and controller is always in the permissible temperature range. If,
though, the cooling system of motor or controller is not operating
correctly (dirt, etc.), there is a risk of damage to the drive from overheating.
INDRAMAT main spindle drives are protected against overheating:
• If the motor or controller temperature approaches the limit of the
temperature range, this is signalled to tyhe controller via the
TEMPWARN alarm output. If the alarm is caused by the motor
temperature, the message MOTWARN appears in the display.
KKWARN appears if it is caused by the controller.
• The drive is switched off automatically if the load is not removed and
the temperature continues to rise.

If KKWARN appears in the display, the drive switches off after 30
seconds and KKTEMP appears in the display.
Drive torque is immediately limited to 50% when KKWARN
appears!
If MOTWARN (winding temperature 145°C) appears and the temperature
continues to rise, the drive switches off at a windings temperature of
155°C and MOTTEMP then appears in the display.
With no temperature sensor connected, the TEMPWARN output is also
active after ten minutes with at least 10% loading. NO TEMP appears in
the display and the drive switches off.
