Process Hold Operation (Virtual Linear Pump) Command
Value via Communications
Program Virtual Linear Pump Virtual Linear Pump Settings
During a properly configured Virtual Linear Pump operation while operating
in the Process Hold mode and using communications for system control, this
parameter establishes the Virtual Linear Pump level.
This parameter setting is effective ONLY while operating in the Process Hold
mode and while receiving a command via communications. The end value of
this parameter setting appears in the Frequency Command screen as shown
below.
Direct Access Number — F487
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes

Acceleration Time 2
Program Special Acc/Dec 1 – 4 Settings
This parameter specifies the time in seconds for the output of the ASD to go
from 0.0 Hz to the Maximum Frequency for the 2 Acceleration profile. The
Accel/Decel pattern may be set using F502. The minimum Accel/Decel time
may be set using F508.
This setting may be adjusted to stabilize unstable Virtual Linear Pump
operation.
This setting is also used to determine the acceleration rate of the UP/DOWN
Frequency Functions.
Note: An acceleration time shorter than the load will allow may cause
nuisance tripping and mechanical stress to loads. Automatic
Accel/Decel, Stall, and Ridethrough settings may lengthen the
acceleration times.
Direct Access Number — F500
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 0.1
Maximum — 6000.0
Units — Seconds
