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 of PT100 characteristic 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.
Setup example) When the PTC input alarm is assigned to the OUT terminal
f131
Setting value 151 is reverse signal.
This function is used to protect motor from overheating using the signal of PTC built-in motor.
The trip display is " e-32 ".
