DESCRIPTION
Sensor Enable

|OptionBits3 [Bit 1]
0x306C 0x00
On / Off
On / Off
When programmed On, the motor temperature cutback and the motor
temperature compensation features are enabled. This parameter can
be used only if a temperature sensor has been properly congured.
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 efciency and more
consistant performance.
Sensor Type
MotorTemp_Sensor_Type

1 – 5
Five sensor types are predened in the software:.
Type 1 KTY83–122
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 ve
predened 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).
Sensor Offset
MotorTemp_Sensor_Offset
0x305A 0x00
–20 – 20°C
–200 – 200
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. The parameter can also be used to correct a known offset
in the sensor itself.
Braking Thermal Cutback Enable

|MotorBrakingThermalCutback_Enable_Bit0 [Bit0]
0x386C 0x00
On / Off
On / Off
When programmed On, drive current and regen braking current will
be cut back based on motor temperature. All forms of regen braking
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 regen braking
current) will be cut back based on motor temperature.
If the vehicle has mechanical brakes, setting this parameter to On
may help reduce motor heating.
Temperature Hot
MotorTemp_Hot
0x304E 0x00
0 – 250°C
0 – 2500
Denes the temperature at which current cutback begins.
Temperature Max
MotorTemp_Max
0x304F 0x00
0 – 250°C
0 – 2500
Denes the temperature at which current is cut back to zero.
MotorTemp LOS Max Speed
MotorTemp_LOS_Max_Speed
0x308A 0x00
100 – 3000 rpm
100 – 3000
When a Motor Temp Sensor Fault (fault code 29) is set, a LOS
(Limited 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.
