Switching Speed Control Constants
In readiness for cases where speed control constants must be changed according to changes in load
or machine conditions, the 3G3M1 has four speed control constants. These can be switched by speed
control parameter selection 1 terminal input “MPRM1” and speed control parameter selection 2
“MPRM2.” Speed control constants 1 and 2 can also be switched by the “SET (2nd control)” terminal.

Speed Command Filter (d01/A43/b43/r43)
This parameter is for setting the time constant of the primary lag filter for the speed set value. Adjust
this parameter, for example, when overshooting in response to changes in the speed command is
large.
Setting a large filter time constant stabilizes the output and reduces overshoot in response to changes
in the speed setting though the speed response becomes slower.
