Electronic Gearing, Master-slave operation

In the case of the "electronic gearing" functionality (see setup software and description of GEAR-
MODE parameter), the servo amplifier is controlled by a secondary feedback device as a slave.
It is possible to set up master/slave systems, use an external encoder as a setpoint encoder or con-
nect the amplifier to a stepper motor control.
The amplifier is parameterized using the setup software (electronic gearing).
Primary Feedback: adjust on screen page "Feedback" (FBTYPE)
Secondary Feedback: adjust on screen pages "Position" and "Gearing" (EXTPOS, GEARMODE)
Master-/Slave adjustment
Master: adjust encoder emulation on screen page "ROD/SSI/Encoder" (ENCMODE)
Slave: adjust on screen pages "Position" and "Gearing" (EXTPOS, GEARMODE)
The following types of external encoder can be used:
Secondary Feedback type
Incremental Encoder 5V
Incremental Encoder 24V
Sine/Cosine Encoder
SSI Encoder
Pulse and Direction 5V
Pulse and Direction 24V
* adjustable via terminal screen of the setup software
