MOTOR TEMPERATURE CONTROL MENU

ALLOWABLE
RANGE
On/Off When programmed On, the motor temperature cutback and the motor
On/Off temperature compensation features are enabled. This parameter can be
used only if a temperature sensor has been properly configured.
The motor temperature cutback feature will linearly cutback the drive
current from 100% to 0% between the Temperature Hot and Temperature
Max temperatures.
The motor temperature compensation feature will adapt the motor
control algorithms to varying motor temperatures, for improved efficiency
and more consistant performance.
1–5 Five sensor types are predefined in the software:.
1–5
Custom sensor types can be set up easily, if none of the five predefined
types is appropriate for your application. Please contact your Curtis
customer support engineer.

Note: The industry standard KTY temperature sensors are silicon
temperature sensors with a polarity band; the polarity band of a KTY
sensor must be the end connected to I/O Ground (pin 7).
-20 – 20 °C Often the sensor is placed in the motor at a location with a known offset
-200–200 to the critical temperature; the offset can be corrected with this parameter.
The parameter can also be used to correct a known offset in the sensor
itself.
0–250 °C Defines the temperature at which drive current cutback begins.
0–2500
0–250 °C Defines the temperature at which drive current is cut back to zero.
0–2500
100–3000 rpm When a Motor Temp Sensor Fault (fault code 29) is set, a LOS (Limited
100–3000 Operating Strategy) mode is engaged. The maximum speed is reduced to
the programmed Max Speed in the operating mode (Max_Speed_SpdMx,
Max_Speed_SpdM, Max_Speed_TrqM) or to the programmed MotorTemp_
LOS_Max_Speed, whichever is lower.
