Electronic Gearing, Master-slave operation
In the case of the “electronic gearing” functionality (see setup software and description of
GEARMODE 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 connect the amplifier to a stepper motor control.
The amplifier is parameterized using the setup software (electronic gearing). The resolu-
tion (number of pulses per revolution) can be adjusted.
The following types of external encoder can be used:

Connection to a SERVOSTAR master, 5 V signal level (X5)
You can link several SERVOSTAR amplifiers together in master-slave operation.
Master:
position autput to X5 (screen page "Encoder emulation")
Slave:
screen page "Electronic gearing" (GEARMODE)
Up to 16 slave amplifiers can be controlled by the master, via the encoder output. The
SubD connector X5 is used for this purpose.
Frequency limit: 1.5 MHz
Example for Master-Slave operation with two SERVOSTAR amplifiers:
