Description

Energy Saving

Energy Savings function enable/disable selection
0: Disabled
1: Enabled
Used to fine-tune the energy savings function.
Accel / Decel
Sets the time to accelerate from zero to maximum frequency.
Sets the time to decelerate from maximum frequency to zero.
Sets the time to accelerate from zero to maximum frequency when
selected via a multi-function input.
Sets the time to decelerate from maximum frequency to zero when
selected via a multi-function input.
Sets the time to decelerate from maximum frequency to zero for
the "Fast Stop" function.
Sets the frequency for automatic switching of accel / decel times.
Fout < C1-11: Accel/Decel Time 2
Fout >= C1-11: Accel/Decel Time 1
Multi-function input "Multi-Acc/Dec 1" has priority over C1-11.

S-Curve Acc/Dec

S-curve is used to further soften the starting ramp.
The longer the S-curve time, the softer the starting
ramp.
