Counter
Drive start and stop can be controlled with counter functions. The counter function
can also be used as state change trigger signal in sequence programming. See

Sequence programming
The drive can be programmed to perform a sequence where the drive shifts typically
through 1 to 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 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 e.g. 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. ACS350 is
supported by version 2.50 (or later version) of the DriveWindow Light PC tool which
includes a graphical Sequence Programming Tool.
