M5.2-1 Motor temperature sensor type “MtempTyp”
This parameter select the type of motor temperature sensor connected to pins 34 and 35 of the 35 Way
connector:
• if set to 0 a KTY84-130 sensor has to be connected;
• if set to 1 a Pt1000 sensor that has 1000 Ohm @0°C has to be connected;
• if set to 2 a Pt1000 sensor that has 1000 Ohm @25°C has to be connected;
• If set to 3 a configurable 5 point Resistance/Temperature curve temperature sensor can be
connected.
Refer to “Pin A34 Thermistor AD4 i/p” and “Pin A35 Thermistor 0V” for details of connection.
M5.2-2 Motor temperature cutback start level “TempStrt”
M5.2-3 Motor temperature cutback span “TempSpan”
M5.2-4 Motor temperature high error level “TempErr”
High temperature cutback
This parameter sets the temperature at which the controller starts to cut back the motor current or the motor
speed, according to “M2-11 Digital output PWM chopping frequency “DO freq”
This parameter can be used to change the chopping frequency used to lower the voltage applied at the digital
outputs.
Use speed limits instead of torque limits “TmpLVSpL””.
The maximum current/speed value is cut as soon as the motor temperature is above “M5.2-2 Motor
temperature cutback start level “TempStrt”” and is cut back proportionally to the temperature between the
starting point and an adjustable span above it, selectable by means of “M5.2-3 Motor temperature cutback
span “TempSpan””.
