5.44.6 Regular Bypass
This function controls the motor speed based on the feedback amount instead of using the
PID. Auxiliary motors may be controlled with this feature based on the feedback amount.

–35 to ’21 (MMC)’ to use the out terminal for auxiliary
motor operation. The number of configured output terminals
determines the total number of auxiliary motors to be used.
When an input set by the PID feedback of the analog input terminal (I or V1 or Pulse) is
100%, divide the area by the number of motors being used (including the main motor).
Each auxiliary motor turns on when feedback reaches the relevant level and turns off when
feedback goes below the relevant level. The primary motor increases its speed based on
the feedback and when it reaches the start frequency of the relevant auxiliary motor and
decelerates to the stop frequency.
The primary motor reaccelerates when the frequency increases, depending on the
