Parameters 263
76.63 IPC smooth
deceleration time
Defines the ramp time that is used to stop the pump.
A pump that is stopped by current master follows the speed
until it is stopped completely. The smooth deceleration time
must be longer than the time defined with parameter 40.33
Set 1 integration time.
Note: Quick ramps overrides the smooth ramp. See
parameter group 82 Pump protections on page 274.
20.00
3.00...1800.00 s IPC smooth deceleration time in seconds. 1 = 1 s
76.70 PFC Autochange Defines the way the autochange is triggered.
In all cases except Even wear, the start order is moved one
step forward each time the autochange occurs. If the start
order initially is 1-2-3-4, after the first autochange the order
will be 2-3-4-1, etc.
For Even wear, the start order will be determined so that the
running times of all motors remain within the defined limit.
Note: Autochange only occurs when the speed of the drive is
below the speed defined by parameter 76.73 Autochange
level.
See also section Autochange on page 63.
Note: This parameter is applicable for PFC/SPFC only.
Not selected
Not selected Autochange disabled. 0
Selected Rising edge starts the autochange if autochange conditions
are met.
1
DI1 Autochange triggered by the rising edge of digital input DI1
(10.02 DI delayed status, bit 0).
2
DI2 Autochange triggered by the rising edge of digital input DI2
(10.02 DI delayed status, bit 1).
3
DI3 Autochange triggered by the rising edge of digital input DI3
(10.02 DI delayed status, bit 2).
4
DI4 Autochange triggered by the rising edge of digital input DI4
(10.02 DI delayed status, bit 3).
5
DI5 Autochange triggered by the rising edge of digital input DI5
(10.02 DI delayed status, bit 4).
6
DI6 Autochange triggered by the rising edge of digital input DI6
(10.02 DI delayed status, bit 5).
7
Timed function 1 Autochange triggered by timed function 1 (bit 0 of 34.01
Timed functions status (see page 191)).
8
Timed function 2 Autochange triggered by timed function 2 (bit 1 of
34.01
Timed functions status (see page 191)).
9
Timed function 3 Autochange triggered by timed function 3 (bit 2 of 34.01
Timed functions status (see page 191)).
10
Fixed interval Autochange is done when the interval determined in the
parameter 76.71 PFC Autochange interval has elapsed.
11
All stop Autochange is done when all the motors are stopped.
The PID sleep feature (parameters 40.43 Set 1 sleep level …
40.48 Set 1 wake-up delay) must be used for the drive to stop
when the process demand is low.
