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
parameter group 35 MOT TEMP MEAS.
The use of the analogue inputs (AI) and outputs (AO) of the module is shown in
the table below.
Motor 1 temperature measurement
AO1 Feeds a constant current to motor 1 temperature sensor. The current
value depends on the setting of parameter 35.01:
- AO1 is 9.1 mA with selection
- AO1 is 1.6 mA with selection
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 parameter 35.04:
- AO2 is 9.1 mA with selection 1xPT100,
- AO2 is 1.6 mA with selection
AI2 Measures voltage over motor 2 temperature sensor.
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 Pt 100 sensor measurement, set the range to 0 ... 2 V.
- for two to three Pt 100 sensors or one to three PTC sensors, set the range to
0 ... 10 V.
3. The operation mode selection is unipolar.
Inactive
Communication active. Module type: RAIO. Connection interface: Option Slot 1
of the drive.
Note: Make the module hardware settings as described above. The node
number is not required. For directions, see RAIO Module User's Manual
[3AFE64484567 (English)].
Communication active. Module type: RAIO. Connection interface: Option Slot 2
of the drive.
Note: Make the module hardware settings as described above. The node
number is not required. For directions, see RAIO Module User's Manual
[3AFE64484567 (English)].
Communication active. Module type: RAIO. Connection interface: Optional I/O
module adapter (AIMA) that communicates with the drive through a fibre optic
DDCS link.
Note: Set the module node number to 9. For directions, see RAIO Module
