Description
Defines the way the autochange is triggered.
In all cases except Even
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
level.

Autochange disabled.
Rising edge starts the autochange if autochange conditions
are met.
Autochange triggered by the rising edge of digital input DI1
(10.02 DI delayed status, bit 0).
Autochange triggered by the rising edge of digital input DI2
(10.02 DI delayed status, bit 1).
Autochange triggered by the rising edge of digital input DI3
(10.02 DI delayed status, bit 2).
Autochange triggered by the rising edge of digital input DI4
(10.02 DI delayed status, bit 3).
Autochange triggered by the rising edge of digital input DI5
(10.02 DI delayed status, bit 4).
Autochange triggered by the rising edge of digital input DI6
(10.02 DI delayed status, bit 5).
Autochange triggered by timed function 1 (bit 0 of
Timed functions status (see page 273)).
Autochange triggered by timed function 2 (bit 1 of
Timed functions status (see page 273)).
Autochange triggered by timed function 3 (bit 2 of
Timed functions status (see page 273)).
Autochange is done when the interval determined in the
parameter 76.71 PFC autochange interval
Autochange is done when all the motors are stopped.
The PID sleep feature (parameters
40.48 Set 1 wake-up delay) must be used for the drive to stop
when the process demand is low.
The running time of the motors are balanced by the drive.
When the difference in running time between the motors with
the least and most running hours exceeds the time defined by
parameter 76.72 Maximum wear
occurs.
The running hours of the motors can be found in group
PFC maintenance and monitoring.
