● p0600 = 1/2/3 selects the additional motor temperature measurement via channels 2 to 4.
● p0601 = 10 activates the evaluation via several temperature channels SME12x.
● p4601[0...n] to p4603[0...n] = 20 sets temperature sensor type KTY.
● If the value in parameter r4620[0...3] is not equal -200 °C, then the temperature display is
valid. The actual value of the temperature sensors is displayed:
– r4620[1] temperature sensors from channel 2
– r4620[2] temperature sensors from channel 3
– r4620[3] temperature sensors from channel 4
● p4601[0...n] to p4603[0...n] = 60 sets temperature sensor type PT1000.
● If the value in parameter r4620[0...3] is not equal -200 °C, then the temperature display is
valid. The actual value of the temperature sensors is displayed:
– r4620[1] temperature sensors from channel 2
– r4620[2] temperature sensors from channel 3
– r4620[3] temperature sensors from channel 4
● p4601[0...n] to p4603[0...n] = 10/11/12 sets the temperature sensor type PTC, the
evaluation type and activates the evaluation.
– p4601[0...n] = 10 PTC fault
– p4601[0...n] = 11 PTC alarm
– p4601[0...n] = 12 PTC alarm and timer
● r4620[0...3] = -200 °C.
● p4601[0...n] to p4603[0...n] = 30/31/32 sets the temperature sensor type bimetal NC
contact, the evaluation type and activates the evaluation.
– p4601[0...n] = 30 bimetal NC contact fault
– p4601[0...n] = 31 bimetal NC contact alarm
– p4601[0...n] = 32 bimetal NC contact alarm and timer
● r4620[0...3] = -200 °C.
