Description
Defines custom scaling for the parameter
pump speed ref src.
Speed reference scalar.
Defines minimum production speed reference in
absolute value.
Minimum production speed.
Defines maximum production speed reference in
absolute value.
Maximum production speed.
Defines the time for the pump-motor to accelerate
from 0 up to the speed set in parameter
scaling.
Note: If parameter 75.23 Ramp switch speed
greater than 0, then this parameter ramp time setting
is used while speed reference is in lower speed region.
Acceleration time in seconds.
Defines the time for the pump-motor to decelerate
from the speed set in parameter
down to 0.
Note: If parameter 75.23 Ramp switch speed
greater than 0, then this parameter ramp time setting
is used while speed reference is in lower speed region.
Deceleration time in seconds.
Defines the speed at which ramp time should switch
from ramp set 1 to ramp set 2.
• Ramp set 1 (75.21 Acceleration time
Deceleration time) is used in speed range from
75.15 Starting speed
speed.
• When speed reference gets higher than
Ramp switch speed, then ramp set 2 is used
Acceleration time 2
2).
• If parameter value is "0", then only ramp set 1 is
used for the complete production speed range.
Ramp switch speed.
Defines the time for the pump-motor to accelerate
from 0 up to the speed set in parameter
scaling.
Note: If parameter 75.23 Ramp switch speed
greater than 0, then this parameter ramp time setting
is used while speed reference is in lower speed region.
Acceleration time 2 in seconds.
