Multi modules application
In complex systems, many motors must be controlled and driven. In such a case more than
one SPMD250STP 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 adjustment and
When at least one motor is relatively large a lower chopper frequency and a slow decay may
be required: In such a case the overall system chopper frequency is determined by the
largest motor in the system as shown in
