Description
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).
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).
Time.
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 255)).
Autochange triggered by timed function 2 (bit 1 of
Timed functions status (see page 255)).
Autochange triggered by timed function 3 (bit 2 of
Timed functions status (see page 255)).
Autochange is done when the interval determined in the
parameter 76.71 Autochange interval
