DETAILED PARAMETER DESCRIPTION
6.3.19 -P42 - Voltage
pulse level at
the start
(Kick Start)
This function determines the voltage level applied to the
motor, so it is able to accelerate the inertia process of the
load, as shown in Figure 6.5.
NOTE!
This function, when enabled, does not permit the activation
of the current limitation during the start.
6.3.20 -
P45 - Pump
Control
Weg has developed for a special algorithm for
application with centrifugal pumps (Quadratic Torque).
This special algorithm is used to minimize pressure
overshoots in the hydraulic pipeline, that can cause
ruptures or excessive wear.

P42 -
Voltage pulse level at the start
NOTE!
Before the first start of the Pump, disable the Pump Control
function. P45 must be set at OFF.
Set the following parameters:
P01 =
30 (Initial Voltage)
P02 =
15 (Acceleration Ramp Time)
P03 =
80 (Voltage Fall Step during Deceleration)
P04 =
15 (Deceleration Ramp Time)
P11 =
OFF (Current Limitation)
After setting the values above start and stop the Pump.
Then check the correct direction of rotation, pump flow and
the Current of the motor.
After the above step you can enable the Pump Control
(P45=ON).
When P45 set at "On" and key "P" is pressed, the
display indicates "PuP" and the following parameters
will be set automatically:
