MOTOR TEMPERATURE CONTROL MENU

ALLOWABLE
RANGE
On/Off When programmed On, the motor temperature cutback and the motor
temperature compensation features are enabled. This parameter can be
On/Off
used only if a temperature sensor has been properly configured.
The motor temperature cutback feature will linearly cut back the
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:.
Type 1 KTY83–122
1–5
Type 2 2× Type 1, in series
Type 3 KTY84–130 or KTY84–150
Type 4 2× Type 3, in series
Type 5 PT1000.
Custom sensor types can be set up easily, if none of the five predefined
types is appropriate for your application. Please contact your Curtis
distributor or 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
to the critical temperature; the offset can be corrected with this parameter.
-200–200
The parameter can also be used to correct a known offset in the sensor itself.
On/Off When programmed On, drive current and all forms of regen braking current
will be cut back based on motor temperature. All forms of regen braking
On/Off
current (Regen_Current_Limit, Brake_Current_Limit, EMR_Current_Limit,
Interlock_Brake_Current_Limit) includes emergency reverse braking,
interlock braking, brake input braking, direction reversal braking, neutral
braking, and speed limit braking.
When programmed Off, only drive current (and not the regen braking
currents) will be cut back based on motor temperature.
If the vehicle has mechanical brakes, setting this parameter to On may
help reduce motor heating.
0–250 °C Defines the temperature at which current cutback begins.
0–2500
0–250 °C Defines the temperature at which current is cut back to zero.
0–2500
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 MotorTemp_LOS_Max_
Speed, whichever is lower.
