Description
Sampling
Time
Sets the internal f/V converter (digital feed forward control) with respect to
dynamics and resolution.
Setting is uncritical. Lower set values result in faster response, but less
accuracy of the feed forward signal. Higher set values result in better
accuracy, but slower response with sudden speed changes.
Please note: Feed forward signals with lower accuracy do not at all affect speed
accuracy of the synchronizing process, but only might cause slight angular errors
.
Depending of the maximum master encoder frequency, the subsequent setting
can be recommended:

Index Mode* Selects the source of the index pulse individually for the Master and Slave
side, where HTL means a Z signal with 18...30 volts level on screw terminal
input and TTL means a Z and /Z signal with TTL level at the Sub-D-encoder
input plugs.
