9.13 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, parameter
GEARMODE).
The resolution (number of pulses per revolution) can be adjusted.
If input X1 is used without the X1 power supply (pins 2, 4, 10, 12), e.g. master-slave oper-
ation with other servoamplifiers, the monitoring of this power supply must be switched off in
order to prevent error message F04 from appearing. To do this, you must change Bit 20 of
the DRVCNFG2 parameter (see ASCII object reference in the online help).
9.13.1 Encoder control types
