Motor Protection Using a Positive Temperature Coefficient (PTC) Thermistor
Connect a motor PTC can to an analog input of the drive for motor overheat protection.
The motor overheat alarm level triggers an oH3 alarm and the drive continues the operation selected in L1-03. The overheat
fault level triggers an oH4 fault, outputs a fault signal, and the drive stops the motor using the stop method selected in L1-04.
Connect the PTC between terminals AC and A3 and install a 12 kOhm resistor between terminals V+ and A3 as shown in
Figure i.20. Set H3-05 to 0 and H3-06 to E.
Note: A 12 kOhm resistor must be connected between one of the terminals A1, A2, or A3 and V+ for PTC functionality. Connect the 12 kOhm
resistor to the same terminal as the PTC input. Do not connect terminals V+ to AC, or damage to the drive may result.
