4.1 Ramp Control description
System control uses fixed ramps to regulate system variable to follow setpoint as described below.
Ramps can be set to one of the preset values:
• Slow: big pump size
• Medium: medium pump size
• Fast: small pump size
Ramp time Ramp 1
Up
Fast 4
Medium 6
Slow 8
The ramp is expressed in seconds and represents the time needed for the motor to go from 0 Hz to the maxi-
mum frequency, or from maximum frequency to 0 Hz.
Ramp 1 (up or down) is always used below minimum frequency/sleep frequency and when feedback value is
outside the regulation band.
Ramp 2 (up or down) is used when feedback value is inside the regulation band.
The motor control will use the ramp-up (1 or 2) till the feedback value reaches the upper limit of the regula-
tion band. Once the upper limit is reached, the motor control will use the ramp-down (1 or 2) till the feed-
back value reaches the lower limit of the regulation band.
