) Note!
l In the Lenze setting, the temperature monitoring of the motor is
switched off!
l If you are dealing with several parameter sets, you must
activate the monitoring in each parameter set!
1. Connect the monitoring circuit of the motor to X2/T1 and X2/T2.
– If 1.6 kΩ <R<4kΩ the monitoring is activated.
2. Set the reaction of the controller:
– C0119 = 0 or 3: Temperature monitoring of the motor is switched off
– C0119 = 1 or 4: TRIP fault message (keypad display: OH3 a)
– C0119 = 2 or 5: Warning signal (keypad display: OH51 e)
Connect the PTC input to a fixed resistor:
l R>4kΩ: A fault message OH3 or OH51 must be initiated.
l R<1kΩ: A fault message must not be initiated.
