Description
Selects PFC control or SPFC control. When enabled, PFC
control or SPFC control does the following:
• Switches in, or out, auxiliary constant speed motors as
output demand increases or decreases. Parameters
START FREQ 1 to
points in terms of the drive output frequency.
• Adjusts the speed regulated motor output down, as
auxiliary motors are added, and adjusts the speed
regulated motor output up, as auxiliary motors are taken
off line.
• Provides Interlock functions, if enabled.
Disabled
PFC control enabled
for alternation applications where lower pressure peaks are
desirable when a new auxiliary motor is started.
Sets the PFC acceleration time for a zero-to-maximum
frequency ramp. This PFC acceleration ramp:
• applies to the speed regulated motor when an auxiliary
motor is switched off
• replaces the acceleration ramp defined in group
ACCEL/DECEL
• applies only until the output of the regulated motor
increases by an amount equal to the output of the
switched off auxiliary motor. Then the acceleration ramp
