DESCRIPTION
Sensor Enable
On/Off
When programmed On, the motor temperature cutback and the motor
MotorTemp_Sensor_Enable
On/Off
temperature compensation features are enabled. This parameter can be
OptionBits3 [Bit 1]
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.
Sensor Type
1–5
Five sensor types are predefined in the software:.
MotorTemp_Sensor_Type
1–5
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 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).
Sensor Temp Offset
-20 – 20 °C
Often the sensor is placed in the motor at a location with a known offset
MotorTemp_Sensor_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.
Temperature Hot
0–250 °C
Defines the temperature at which drive current cutback begins.
MotorTemp_Hot
0–2500
Temperature Max
0–250 °C
Defines the temperature at which drive current is cut back to zero.
MotorTemp_Max
0–2500
MotorTemp LOS Max Speed 100–3000 rpm When a Motor Temp Sensor Fault (fault code 29) is set, a LOS (Limited
MotorTemp_LOS_Max_Speed
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.
