Manual SD6
Indicates whether the encoder connected to X4 is a rotational or translational
measuring system. This affects the unit of measure of
H01
and determines
whether the encoder will be located before or after the feed in the axis model.
Coding type of the angle by the SSI encoder.
Adjusts the clock frequency of the serial transfer for querying the SSI encoder.
A higher clock frequency allows for better control because the position is
transferred faster and can therefore be queried more frequently overall.
However, not all SSI encoders support the high clock frequencies.
Shows a description of the encoder found on X4.
Element 0
For EnDat® 2.2 this is the designation of the encoder.
For EnDat® 2.1 the string is formatted as follows: "ED 2.1 <number of bits>
<number of multi-turns>MT"
"SSI" is displayed for SSI encoders and "Incremental enc." for incremental
encoders.
Element 1
Element 1 is the output voltage measured on X4. It varies according to the
length and cross-section of the encoder cable as well as the encoder power
consumption. If the sense signal is used, the voltage is controlled so that the 5
V match exactly at the location of the encoder (in the motor).
Element 2
Element 2 is the output current measured on X4.
The parameter indicates the number of data bits transferred via SSI. The
meaning of the bits can be specified with parameters
H01
and
H02
. Typically
there are 13 bits per revolution for rotational SSI encoders. This corresponds
to
H02
= 8192 LSBs and
H01
= 10,000 revolutions.
Switches off double transfer for SSI encoder. When double transfer is activated
the angle is queried twice in a row with a continuous clock to achieve greater
data security. If the encoder does not support double transfer, double transfer
must be turned off with this parameter. If double transfer is turned off, the drive
controller will no longer generate a second query.

Information
If the hardware that is used allows it, double transfer should not be
deactivated.
