THERMISTOR
(0) – Sensor configuration uses a thermistor.
• Motor thermal protection is activated through a digital input. Connect either a PTC sensor or a normally closed
thermistor relay to a digital input. The drive reads the digital input states as shown in the above table.
• When the digital input is ‘0’ the motor is overheated.
• See the figures in the introduction to this Group.
6 =
THERMISTOR
(1) – Sensor configuration uses a thermistor.
• Motor thermal protection is activated through a digital input. Connect a normally open thermistor relay to a digital
input. The drive reads the digital input states as shown in the above table.
• When the digital input is ‘1’ the motor is overheated.
