H70 Frequency Reference for Accel/Decel

Range: 0 - 1

Default: 0

Access Configurable

See Also: P36, P41, P42, H71

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.
