3: No warning
Sets the operation mode of a drive after you set Pr.06-29 to define PTC detection.
Running a motor at low frequency for a long time reduces the cooling function of the motor fan. To
prevent the motor from damage due to overheating, use a Positive Temperature Coefficient
thermistor on the motor, and connect the thermistor output signal to the drive’s analog input
terminals.
