Parameters 423
0.0...1800.0 s Acceleration time in seconds. 1 = 1s‘
75.22 Deceleration time Defines the time for the pump-motor to decelerate from the
speed set in parameter 46.02 Frequency scaling down to 0.
Note: If parameter 75.23 Ramp switch speed is set to greater
than 0, then this parameter ramp time setting is used while
speed reference is in lower speed region.
30.0
0.0...1800.0 s Deceleration time in seconds. 1 = 1s
75.23 Ramp switch speed Defines the speed at which ramp time should switch from
ramp set 1 to ramp set 2.
• Ramp set 1 (75.21 Acceleration time and 75.22
Deceleration time) is used in speed range from 75.15
Starting speed up to 75.23 Ramp switch speed.
• When speed reference gets higher than 75.23 Ramp
switch speed, then ramp set 2 is used (75.24 Acceleration
time 2 and 75.25 Deceleration time 2).
• If parameter value is "0", then only ramp set 1 is used for
the complete production speed range.
0.00
0.00...600.00 Hz Ramp switch speed. 10 = 1Hz
75.24 Acceleration time 2 Defines the time for the pump-motor to accelerate from 0 up
to the speed set in parameter 46.02 Frequency scaling.
Note: If parameter 75.23 Ramp switch speed is set to greater
than 0, then this parameter ramp time setting is used while
speed reference is in lower speed region.
30.0
0.0...1800.0 s Acceleration time 2 in seconds. 1 = 1s
75.25 Deceleration time 2 Defines the time for the pump-motor to decelerate from the
speed set in parameter 46.02 Frequency scaling down to 0.
Note: If parameter 75.23 Ramp switch speed is set to greater
than 0, then this parameter ramp time setting is used while
speed reference is in lower speed region.
30.0
0.0...1800.0 s Deceleration time 2 in seconds. 1 = 1s
