Sets Device current limit. Sets motor starting current
limit if parameter "N" is properly adjusted.
The maximum range setting is automatically calculated
by the unit according the following expression:
Lmax = 450 ( ); Max 450
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.

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: Parameter "p" is disabled while "C" is ON.
Choice of various pump control algorithms for starting:
0: Voltage ramp up
01-03: Various pump algorithms
Choice of various pump control algorithms for stopping phase:
0: Voltage ramp down
01-05: Various pump algorithms
Enables or disables the Kick start function.
If Pump control function “C” is enabled, both Kick start and DC Brake
functions are internally disabled.
This function provides control of an external by-pass contactor,
significantly lowering heating losses and eliminating harmonics.
The programmable relay output 2r is assigned to this function, and
must be used to control the external by-pass contactor.

Notes:
- Curve 0 (both ST00, SP00):
Standard voltage ramp up -starting- and ramp down -soft stop-
- Curve 1 (both ST01, SP01): Pump Algorithm based on estimated average PF -power factor- , with large sampling period.
- Curve 2 (both ST02, SP02): Pump Algorithm based on instantaneous PF with short sampling period.
- Curve 3 (both ST03, SP03): Pump Algorithm based on estimated average PF with short sampling period. Application:
low pressure system/low flow rate change.
- Curve 4 (SP04): Same as Curve 3, but with higher accuracy on PF average estimation. Application: high head
pressure/low flow rate change.
- Curve 5 (SP05): Pump Algorithm based on former ASTAT-CD.
