34.05 TORQ ACT FILT TIM Defines a filter time for the actual signal torque (actual signal 01.05 ). Affects
also on the torque read through an analogue output.
0 … 20000 ms Filter time constant 0 … 20000
35 MOT TEMP MEAS
Motor temperature measurement. For the function description, see sections
Motor temperature measurement through the standard I/O interface on page
81 and Motor temperature measurement through an analogue I/O extension
on page 83 .
35.01 MOT 1 TEMP AI1 SEL Activates the motor 1 temperature measurement function and selects the
sensor type.
Note: If an optional analogue I/O extension module RAIO is used for the
temperature measurement and 35.01 MOT 1 TEMP AI1 SEL and/or 35.04
MOT 2 TEMP AI2 SEL are set to 1xPT100, analogue extension module input
signal range must be set to 0 ... 2 V (instead of 0 ... 10 V) with DIP switches.
NOT IN USE The function is inactive. 1
1xPT100 The function is active. The temperature is measured with one Pt 100 sensor.
Analogue output AO1 feeds constant current through the sensor. The sensor
resistance increases as the motor temperature rises, as does the voltage over
the sensor. The temperature measurement function reads the voltage through
analogue input AI1 and converts it to degrees centigrade. 2
2XPT100 The function is active. Temperature is measured using two Pt 100 sensors.
See selection
1xPT100 .
3
3XPT100 The function is active. Temperature is measured using three Pt 100 sensors.
See selection
1xPT100 .
