Actual signals and parameters
210
PTC
The function is active. The temperature is supervised using PTC sensor.
Analog output AO feeds constant current through the sensor. The resistance
of the sensor increases sharply as the motor temperature rises over the PTC
reference temperature (Tref), as does the voltage over the resistor. The
temperature measurement function reads the voltage through analog input
AI1/2 and converts it into ohms. The figure below shows typical PTC sensor
resistance values as a function of the motor operating temperature.
4
THERM(0)
The function is active. Motor temperature is monitored using a PTC sensor
(see selection PTC) connected to drive via a normally closed thermistor relay
connected to a digital input. 0 = motor overtemperature.
5
THERM(1)
The function is active. Motor temperature is monitored using a PTC sensor
(see selection PTC) connected to drive via a normally open thermistor relay
connected to a digital input. 1 = motor overtemperature.

INPUT SELECTION
Selects the source for the motor temperature measurement signal.
AI1
AI1
Analog input AI1. Used when PT100 or PTC sensor is selected for the
temperature measurement.
1
AI2
Analog input AI2. Used when PT100 or PTC sensor is selected for the
temperature measurement
2

ALARM LIMIT
Defines the alarm limit for motor temperature measurement. Alarm MOTOR
TEMP indication is given when the limit is exceeded. When par.
SENSOR TYPE value is set to THERMI(0)/(1): 1 = alarm.
