262 Parameters
76.55 Start delay Defines the delay time for starting the auxiliary motors.
See parameter
76.31 Start point 1 .
10.00 s
0.00…12600.00 s Time delay. 1 = 1 s
76.56 Stop delay Defines the delay time for stopping the auxiliary motors. See
parameter
76.31 Stop point 1 .
10.00 s
0.00…12600.00 s Time delay. 1 = 1 s
76.57 PFC speed hold on Hold time for auxiliary motor switch-on. See parameter 76.31
Start point 1 .
0.00 s
0.00…1000.00 s Time. 1 = 1 s
76.58 PFC speed hold off Hold time for auxiliary motor switch-off. See parameter 76.31
Stop point 1 .
0.00 s
0.00…1000.00 s Time. 1 = 1 s
76.59 PFC contactor
delay Start delay for the motor that is directly controlled by the drive.
This does not affect the starting of the auxiliary motors.
WARNING! There must always be a delay set if the
motors are equipped with star-delta starters. The
delay must be set longer than the time setting of the
starter. After the motor is switched on by the relay output of
the drive, there must be enough time for the star-delta starter
to first switch to star and then back to delta before the motor
is connected to the drive.
0.50 s
0.20…600.00 s Time delay. 1 = 1 s
76.60 PFC ramp
acceleration time Defines the acceleration time for the drive motor speed
compensation, when an auxiliary motor is stopped. This ramp
time is also used for the drive motor to accelerate after an
autochange has occurred.
The parameter sets the ramp-up time as seconds from zero
to maximum frequency (not from the previous reference to
the new reference). 1.00 s
0.00…1800.00 s Time. 1 = 1 s
76.61 PFC ramp
deceleration time Defines the deceleration time for the drive motor speed
compensation, when an auxiliary motor is started. This ramp
time is also used for the drive motor to decelerate after an
autochange has occurred.
The parameter sets the ramp-up time as seconds from
maximum to zero frequency (not from the previous reference
to the new reference). 1.00 s
0.00…1800.00 s Time. 1 = 1 s
76.62 IPC smooth
acceleration time Defines the ramp time of a new starting pump.
A pump that is started by current master follows the speed
until all the pumps rotate at the same speed and master role
is changed. The smooth acceleration time must be longer
than the time defined with parameter
40.33 Set 1 integration
time .
Note: Quick ramp overrides the smooth ramp. See parameter
group 82 Pump protections on page 274 .
20.00
3.00...1800.00 s IPC smooth acceleration time in seconds. 1 = 1 s
No. Name/Value Description Def/FbEq16
