Sets Device current limit. Sets motor current limit if pa-
rameter "N" is properly adjusted.
The maximum range setting is automatically calculated
by the unit according the following expression:
Max Limit = 450 / N (max allowed is 700%)
N is the motor capacity / unit capacity ratio adjusted in
parameter "Nxxx".
Sets the initial voltage applied to the motor
Sets Voltage ramp up time. Motor acceleration time will
depend of load conditions.
Sets Voltage ramp down time. Motor deceleration time
will depend of load conditions.
Enabled only if the parameter "Sxxx" is ON
During the time adjusted, provides 95% of full voltage to
motor at starting time. Useful for high static-friction loads
Enabled only if the parameter "Pxxx" is ON
Provides DC braking at stopping time.
Enabled only if the parameter "Bxxx" is ON

Enables or disables all modes of Soft stop
Enables the Pump control function. Usefull to limit fluid hammering.
The parameter "Sxxx" must also be enabled.
NOTE: Parameters "p ", "b " and "I " are disabled while "C" is ON

Enables or disables the KIck start function
If Pump control function C is enabled, both Kick start and DC Brake
functions are internally disabled
When this function is enabled, the unit provides constant full voltage
after starting, producing the lowest harmonic distortion. Note that the
energy saving function is disabled when Override is enabled.

Notes:
- Curve 00 (both ST00, SP00): Standard voltage ramp up -starting- and ramp down -soft stop-
- Curve 01 (both ST01, SP01): Pump Algorithm based on estimated average PF -power factor- , with large sampling period
- Curve 02 (both ST02, SP02): Pump Algorithm based on instantaneous PF with short sampling period
- Curve 03 (both ST03, SP03): Pump Algorithm based on estimated average PF with short sampling period
- Curve 04 (SP04):
As Curve 3, but with high accuracy on PF average estimation
- Curve 05 (SP05):
Pump Algorithm based on former ASTAT CD
