Sequence programming

The drive can be programmed to perform a sequence where the drive shifts typically
through 1...8 states. User defines the operation rules for the whole sequence and for
each state. The rules of a particular state are effective when the Sequence program is
active and the program has entered the state. The rules to be defined for each state
are:
• Run, stop and direction commands for the drive (forward/reverse/stop)
• Acceleration and deceleration ramp time for the drive
• Source for the drive reference value
• State duration
• RO/DO/AO status
• Signal source for triggering the shift to the next state
• Signal source for triggering the shift to any state (1...8).
Every state can also activate drive outputs to give an indication to external devices.
Sequence programming allows state transitions either to the next state or to a
selected state. State change can be activated with eg timed functions, digital inputs
and supervision functions.
Sequence programming can be applied in simple mixer applications as well as in
more complicated traverse applications.
The programming can be done with control panel or with a PC tool. The drive is
supported by version 2.91 or later of the DriveWindow Light 2 PC tool which includes
a graphical Sequence programming tool.
Note: By default all Sequence programming parameters can be changed even when
the Sequence programming is active. It is recommended that after the Sequence
programming parameters are set, parameters are locked with parameter
PARAMETER LOCK.
