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.

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
. The minimum Accel/Decel time
may be set using
.
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.
