32 VS-616G5 Programming Manual
If any of the parameters C1-01 to C1-09 is set to 600.1 seconds or more, C1-10 cannot be set to “0”.
Setting Range: 0.0 to 400.0Hz
Factory Default: 0.0Hz
Accel/decel times can be changed automatically, without using the multi-function contact inputs.
Use accel/decel times set in parameters C1-01 and C1-02 when output frequency
≥
C1-11.
Use accel/decel times set in parameters C1-07 and C1-08 when output frequency < C1-11.
When multi-function contact inputs are set for accel/decel selection, this command has priority over
automatic change of accel/decel.
C2 S-Curve Accel/Decel
An S-curve pattern is used to reduce shock and provide smooth transitions during machine accelera-
tion and deceleration. S-curve characteristic time is the time from the output frequency to the set accel/
decel time.
Setting Range: 0.00 to 2.50s
Factory Default: 0.20s

Setting Description
0 Accel/decel time (C1-01 to C1-09) setting range is in units of 0.01 second.
Accel/decel time setting range: 0.00 to 600.00s
1 Accel/decel time (C1-01 to C1-09) setting range is in units of 0.1 second.
