Parameter
number
Parameter name Unit of measurement Description
P27 Min RPM set
[Min*-ACT set]
G
rpmx10 Minimum pump speed setup.
P28 Ramp 1 [1–250]
G
s This parameter adjusts the fast acceleration time.
It affects the control of the pump for HCS, MSE and
MSY control modes (also see Par. 6.6.2).
Default: 3 s.
P29 Ramp 2 [1–250]
G
s This parameter adjusts the fast deceleration time
It affects the control of the pump for HCS, MSE and
MSY control modes (also see Par. 6.6.2).
Default: 3 s.
P30 Ramp 3 [1–999]
G
s This parameter adjusts the slow acceleration.
It determines:
• The Hydrovar ® adjustment speed, in case of small
flow rate variations
• The constant outgoing pressure.
The ramp depends on the system being controlled,
and affects the control of the pump in HCS, MSE and
MSY modes (also see Par. 6.6.2).
Default: 35 s.
P31 Ramp 4 [1–999]
G
s Adjustment of the slow deceleration time (also see
Par. 6.6.2).
Other characteristics: as for Ramp 3.
P32 Ramp Speed Min
Acceleration [2.0-25.0]
G
s This parameter sets the fast acceleration time.
It represents the acceleration ramp used by the
Hydrovar
®
controller until the minimum speed of the
pump is reached (P27).
It affects the control of the pump for HCS, MSE and
MSY control modes (also see Par. 6.6.2).
Default: 2.0 s.
P33 Ramp Speed Min
Deceleration [2.0-25.0]
G
s This parameter sets the fast deceleration time.
It represents the deceleration ramp used by the
Hydrovar ® controller for stopping the pump once the
minimum speed of the pump is reached (P27).
It affects the control of the pump for HCS, MSE and
MSY control modes (also see Par. 6.6.2).
Default: 2.0 s.
