Description
Activates the communication to the analogue I/O extension module
and reserves the module for the use of the motor temperature
measurement function. The parameter also defines the type and
connection interface of the module.
For more information on the temperature measurement function, see
group 35 MTR TEMP MEAS.
The use of the analogue inputs (AI) and outputs (AO) of the module is
shown in table below.Before setting the drive parameters, ensure the
module hardware settings are appropriate for the motor temperature
measurement:
1. The module node number is 9.
2. The input signal type selections are the following:
- for one Pt100 sensor measurement, set the range to 0...2 V.
- for two to three Pt100 sensors or one to three PTC sensors, set
the range to 0...10 V.
3. The operation mode selection is unipolar.
Motor 1 Temperature Measurement
AO1 Feeds a constant current to motor 1 temperature sensor.
The current value depends on the setting of
TEMP SEL:
- AO1 is 9.1 mA with selection 1xPT100
- AO1 is 1.6 mA with selection 1..3 PTC
AI1 Measures voltage over motor 1 temperature sensor.
Motor 2 Temperature Measurement
AO2 Feeds a constant current to motor 2 temperature sensor.
The current value depends on the setting of
TEMP SEL:
- AO2 is 9.1 mA with selection 1xPT100,
- AO2 is 1.6 mA with selection 1..3 PTC
AI2 Measures voltage over motor 2 temperature sensor.
