SELECT X
x = SSI|ANA
IO_CONFIG
The appropriate sensor type can be activated with this command.
SSI
:
The SSI sensor interfaces are active. The SSI sensors have to be adjusted via the SSI
commands to the sensors. The relevant sensor data must be available
ANA
: The analogue sensor interfaces are active.
The SSI interface is suitable for digital position sensor. The internally processed accuracy is 1
micron.
WARNING
: The two SSI sensors must be of the same type, i.e. resolution of the sensor,
number of bits transmitted and transmission coding must be the same!

The rate of change of external speed demand can be limited by these ramp times.
In NC mode, these parameters should be set to 10 ms.

IO_CONFIG
This command is used to define the output signal (voltage or current) and to change the polarity.
Differentia
l output ± 100 % corresponds with ± 10 V (0… 10 V at PIN 15 and PIN
16 or PIN 19 and
PIN 20).
Current output ± 100 % corresponds with 4… 20 mA (
PIN 15 to PIN 12 or PIN 19 to PIN 18).
12 mA (0 %) = centre point of the valve.
An output current of < 4 mA indicates an error and the module is disabled. The current
input of the proportional valves should be monitored by the valve. The valve has to be
deactivated in case of < 4 mA input signal, otherwise the EOUT command can be used
to get a defined output signal.
