Description
E
Motor Temperature (PTC Input)
Uses the motor Positive Temperature Coefficient (PTC) thermistor to prevent heat damage to the motor as a percentage of the current value when the 10 V analog signal is input.
You can use the Positive Temperature Coefficient (PTC) thermistor as an auxiliary or alternative detection function for oL1 [Motor Overload] problems to help prevent heat damage to motors. If the PTC input signal is more than the overload alarm level, oH3 [Motor Overheat (PTC Input)] will flash on the keypad.
When the drive detects oH3, the motor stops with the setting in L1-03. When the drive detects oH4, the motor stops with the setting in L1-04. When the drive incorrectly detects motor overheating problems, set L1-05.
