FP5/GP5 Operation
The following figure shows FWD/REV run switching during deceleration to stop.
Speed Limit Adjustment
·Frequency Reference Upper Limit (n031, Ref Upper Limit)
The upper limit of the frequency reference can be set in increments of
1%. (n011: maximum output frequency = 100%)
Factory setting: 100%
·Frequency Reference Lower Limit (n032, Ref Lower limit)
The lower limit of the frequency reference can be set in increments of
1%. (n011: maximum output frequency = 100%)
Factory setting: 0%
When operating at a frequency reference of 0Hz, operation continues at
the frequency reference lower limit. However, when the lower limit is set
to less than the minimum output frequency (n016), operation stops.
