Default:
Access
See Also:
0 = Based on P36 – Frequency High Limit
1 = Based on Delta Frequency
Set the desired Accel/Decel time sin P41 and P42. If H70 = 0, the
acceleration and deceleration time is the time that it takes to reach
maximum frequency from 0 hertz. If you set H70 to 1 = Delta Frequency,
Accel/Decel time is the time that it takes to reach target frequency from a
constant run frequency (current operating frequency). To scale the time
units for accel/decel set parameter H71.
