5.3.1 Hoist motor overheating supervision instructions
Param. Name Description
4-4 T1 Temperature measurement channel 1 parameters
Selects the function of temperature measurement channel 1:
NU Not used
Motor without thermistors or only one sensor that is connected to the
temperature input 2.
PTC
Motor thermistor or
Bimetal thermal switch Two speed motors typically only have one set of thermistors, for both low speed
and high speed windings.
Bwear Brake wear sensor See section Hoist Brake- Wear supervision
A NTC Type A NTC sensor
B NTC Type B NTC sensor
4-4-1 T1 operat.
C NTC Type C NTC sensor
Determines the type of thermistors in the low speed windings, connected to the
temperature input 1
Manufacturer’s hoisting motors used in motor-torque calculation overload
systems are as a standard equipped with type B NTC thermistors

4-10-1
OT run ? No / Down Hoisting and lowering is prevented when the
overtemperature supervision trips. If, for safety reasons, local legislation or customer demands,
lowering the load is required when the temperature supervision
has tripped, set this parameter to: “Down”
4-10-2
OT limit 150C Sets the tripping level of the overtemperature
supervision in degrees Celsius, steps of one
degree. Only with NTC-thermistor. Consult with the motor data sheets for the maximum allowed
temperature for the motor. Default for manufacturer’s squirrel
cage motors: 150°C
