(2) INP (In-position)
INP turns on when the number of droop pulses in the deviation counter falls within the preset in-position
range ([Pr. PA10]). INP may turn on continuously during a low-speed operation with a large value set as
the in-position range.

(4) Electronic gear switching
The combination of CM1 and CM2 enables you to select four different electronic gear numerators set in
the parameters.
As soon as CM1/CM2 is turned on or off, the numerator of the electronic gear changes. Therefore, if a
shock occurs at switching, use the position smoothing ([Pr. PB03]) to relieve the shock.
