Code Description
5 = (0) – Sensor configuration uses a thermistor.
THERM
• Motor thermal protection is activated through a digital input. Connect
either a normally closed thermistor relay or a PTC sensor to a digital
input.
• When the digital input is '0', the motor is overheated.
• See the connection figures on page 262.
• The table below and the graph on page
requirements for a PTC sensor connected between 24 V and digital
input as a function of the motor operating temperature.

6 = (1) – Sensor configuration uses a thermistor.
THERM
• Motor thermal protection is activated through a digital input. Connect
a normally open thermistor relay to a digital input.
• When the digital input is '1', the motor is overheated.
• See the connection figures on page 262.
