22-86 Speed at Design Point [Hz] 60.0 Hz 60.0 Hz Speed required to maintain
the design point. Use this
parameter when flow
compensation is enabled.
See figure 3, point B.
22-87 Pressure at No Flow Speed 0.000 0.000 Pressure developed at no
flow speed. Use this
parameter when flow
compensation is enabled.

3-41 Ramp 1 Ramp Up Time 10 s 10 s Ramp up time (0 to full
speed). Increasing this
time will produce a slower
ramp up.
