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.
H70 = 0 (Max Frequency)
H70 = 1 (Delta Frequency)
