PTC Detection Selection
Default: 0
Settings 0: Warn and continue operation
1: Fault and ramp to stop
2: Fault and coast to stop
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.

0.0–100.0%
 Sets AVI / ACI analog input function Pr.03-00 to 6 [Positive temperature coefficient (PTC)
thermistor input value].
