MULTI MODULES APPLICATION
In complex systems, many motors must be control-
led and driven. In such a case more than one
GS-D200 or GS-D200 S must be used.
To avoid chopper frequencies noise and beats, all
the modules should be synchronized.
If all the motors are relatively small, the fast decay
may be used, the chopper frequency does not need

any adjustement and fig. 18 shows how to synchro-
nize several modules.
When at least one motor is relatively large a lower
chopper frequency and a slow decay may be re-
quired: In such a case the overall system chopper
frequency is determined by the largest motor in the
system as shown in fig. 19.
