Shaded Areas
■
B-04 (DIST1): A location where sudden speed reduction takes place for stop. The higher this value, the more stable
speed reduction, but final stop distance will be longer.
■
B-08 (KC2): Can be calculated by inertia tuning. The higher this value, the slower the distance tracking. (FOR
PROFESSIONAL ENGINEERS ONLY)
■
B-12 (KF2): Can be calculated by inertia tuning. The higher this value, the slower the speed tracking. (FOR
PROFESSIONAL ENGINEERS ONLY)
■
B-15 (accelA): Can be calculated by inertia tuning. This represents speed reduction from after pedal stop signal input
to sudden stop. The higher value means sudden slowdown, but too high value may result in inability to
sudden slowdown.
■
B-17 (accelB): Represents level of speed acceleration by pedal. The higher this value, the higher acceleration to the
target speed, but speed fluctuation may also increase when reaching the target speed.
■
B-18 (accelC): Represents level of speed reduction by pedal. The higher this value, the faster reduction of speed to the
target speed, but speed fluctuation may also increase when reaching the target speed.

Examples of the shaded functions
①
Unable to come to sudden stop and stops at one more stitch
– This happens when the machine has been operating at a very high speed or when the workload is large and the
machine cannot reduce speed in short time. Increase B-04 and B-15 values to an appropriate level.
②
Motor is slow to adjust to new speed when machine speed is changed
– This happens when the speed change level is smaller than the machine workload change. Increase B-17 and B-18
values to an appropriate level.
