6. Motor PTC thermal protection
Set a parameter f147 and lower slide switch of SW2 to PTC side, when S3 terminal is used as PTC input terminal.
f147 : Logic input / PTC input selection (S3)
f645 : PTC thermal selection
f646 : Resistor value for PTC detection
• Function
This function is used to protect motor from overheating using the signal of PTC built-in motor.
The trip display is “e-32”.

PTC detection resistor value 100-9999 (Ω) 3000
Note : Protecting PTC thermal, set f147=1 (PTC input) and slide switch SW2 to PTC side.
● Tripping level is defined by f646 setting. Alarm level is defined by 60% of f646 setting.
● Connect the PTC between S3 and CC terminals. Detection temperature can be set by f646 setting.
[Connection]
● Output of PTC input alarm signal
The PTC input alarm is assigned to the output terminal by setting the parameter of the output terminal selection
function to 150 or 151.
