PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Sensor Enable
MotorTemp_Sensor_Enable
0x3686 0x00
On/Off
On/Off
Off When programmed On, this parameter enables both the motor
temperature cutback and the motor temperature compensation
features. For this parameter to be valid, properly congure the
temperature sensor.
The motor temperature cutback feature linearly cuts 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 a more
consistent performance.
Temperature
Motor_Temperature
0x3536 0x00
–100.0 – 300.0
–1000 – 3000
Read Only Temperature sensor readout.
Motor Temp Cutback
MotorTempCutback
0x3439 0x00
0.00 – 100.00 %
0 – 4096
Read Only Displays the available current resulting from the motor
temperature cutback function. A value of 100% indicates no
cutback in current.
Temperature Hot
MotorTemp_Hot
0x3683 0x00
0 – 250 °C
0 – 2500
145 °C Denes the temperature at which current cutback begins.
Temperature Max
MotorTemp_Max
0x3685 0x00
0 – 250 °C
0 – 2500
160 °C Denes the temperature at which current cut back is zero.
Motor Temp LOS Max Speed
MotorTemp_LOS_Max_Speed
0x3684 0x00
100 – 3000 rpm
100 – 3000
800 rpm When a Motor Temp Sensor Fault (fault code 29) is set, it engages
the LOS (Limited Operating Strategy) mode. This reduces the
maximum speed to the programmed Max Speed. The speed is
the lower of the speed mode’s settings (Max_Speed_SpdMx
or Max_Speed_SpdM), or to the MotorTemp_LOS_Max_Speed
setting, whichever is lower.
Sensor Type
MotorTemp_Sensor_Type
0x3688 0x00
0 – 4*
0 – 4
* Enumeration:
Custom
KTY83
KTY84-130
KTY84-150
PT1000
4 Sensor types are predened in the software:
Type 0- Custom
Type 1 KTY83-122
Type 2 KTY84-130
Type 3 KTY84-150
Type 4 PT1000
Custom sensor types are congurable, if none of the ve
predened types is appropriate for the application. Low resistance
sensors, such as the PT100, are not congurable. Contact the
Curtis distributor or support engineer for custom sensors.
Note: KTY silicon temperature sensors have a polarity band,
which must be the end connected to I/O Ground (pin 18 or 7).
Sensor Offset
MotorTemp_Sensor_Offset
0x3687 0x00
–20 – 20 °C
–200 – 200
0 °C When a sensor in the motor is located with a known offset to the
critical temperature, correct the offset using this parameter. Also,
use this parameter to correct a known offset in the sensor itself.
