The servo amplifier receives a position setpoint from another instrument (master servo amplifier, stepper motor
control, encoder or similar) and controls the position of the motor shaft in synchronism with this master (control)
signal.
Cycle time of the electrical gearing: 250 µs. A value averaged over 1000 µs is used.
Gearing mode
ASCII: GEARMODE
The servo amplifier can be controlled through different interfaces and from various sources.
For the connector pin assignments, see the Installation Manual.

With an incremental encoder (track A/B, 24V signal level) connected to the
digital inputs DIGITAL-IN ½, terminals X3/11,12. An additional function
assignment for the inputs is not necessary, and any assignments on the
screen page "Digital I/O" will be ignored.

Set encoder emulation to "INPUT". With an incremental encoder (track A/B,
5V signal level) connected to connector X5. In this case, the incremental
position signal from another amplifier can be used as the master signal.

With a sine/cosine encoder connected to connector X1.
Read in the SSI position via the Encoder interface. Every 250µsec the SSI
position is captured and the difference to the preceding position is calculated.
Subsequently, this difference is multiplied by the scaling factor and added to
the last position setpoint.
