Operating Instructions (Compact) 
A high thermal motor load and when the line supply is frequently switched-
out/switched-in requires, for closed-loop vector control 
−  that a KTY84 sensor is used, or 
−  an external 24V power supply voltage is connected 
 
Motor cooling
 
(Selects motor cooling system used) 
  0  Self-cooled: Using shaft mounted fan attached to motor 
  1  Force-cooled: Using separately powered cooling fan 
 2  Self-cooled and internal fan 
  3  Force-cooled and internal fan 
 
Motor temperature sensor 
Selects the motor temperature sensor. 
 0  No sensor 
 1  PTC thermistor (PTC) 
 2  KTY84

Alarm threshold, motor overtemperature 
Defines the alarm threshold for the motor overtemperature protection. This threshold, where 
either a shutdown (trip) or Imax reduction is initiated (P0610) always lies 10 % above the 
alarm threshold.

Warning threshold (P0604)
 
The alarm threshold should be at least 40 °C greater than the ambient temperature P0625.

Motor overload factor [%] 
Defines motor overload current limit in [%] relative to p0305 (rated motor current). Limited to 
maximum inverter current or to 400 % of rated motor current (p0305), whichever is the 
lower.
