7.13 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 enco-
der 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 ope-
ration 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).
