10.2.3.2
Electronic gearing, Master-Slave operation (X5)
10.2.3.2.1
Connection to S748/772 master, 5V signal level (X5)
You can link several S748/772 amplifiers together in master-slave operation.
Master:
Slave:
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 S748/772 amplifiers, ROD emulation is
used:
Slave GEARMODE: 3
If SSI emulation is used, the master ENCMODE must be set to 2 and the slave
GEARMODE to 5.
10.2.3.2.2
Connection to stepper motor controllers with 5 V signal level (X5)
Wiring of the servo amplifier (SubD connector X5) to a stepper-motor controller with a 5 V
signal level.
Frequency limit: 1.5 MHz
Type
Step/Direction 5V
