5.4 Input signal adaption

SELECT:X (Type of position sensors)

Command
SELECT
With this parameter, the appropriate sensor type can be activated.
SSI: The SSI sensor interfaces are active. The SSI sensors have to be adjusted via the SSI com-
mands to the sensors. The relevant sensor data must be available.
ANA: The analog sensor interfaces are active.
The SSI interface is suitable for digital position sensor. The internally processed accuracy is 1 micron.
CAUTION: The two SSI sensors must be of the same type, i.e. the resolution of the sensor, the
number of bits transmitted and the transmission coding must be the same!

SSI:RES (Signal resolution)

Command
SSI:RES
This command defines the signal resolution of the sensor. Data entry has a resolution of 10 nm (nanometers
or 0.01 micron). If the sensor has one-micron resolution, the value must be set to 100. This makes it possible
to scale rotational sensors too.
Take the data from the sensor's data sheet.

SSI:BITS (Number of bits)

Command
SSI:BITS
With this command the number of data bits can be set.
Take the data from the sensor's data sheet.
