DESCRIPTION
Sensor Enable
|MotorTemp_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

0 – 9
0 – 9
Nine 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.
Type 6 SDN16_FKFN_X.
Type 7 KTY84_150.
Type 8 Omega 44004.
Type 9 KTY81_110.
Custom sensor types can be set up using VCL, if the predened types
are not appropriate for the application. Please contact the 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
|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.
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.
