Program features133CounterDrive start and stop can be controlled with counter functions. The counter functioncan also be used as state change trigger signal in sequence programming. Seesection Sequence programming on page 133.SettingsDiagnosticsSequence programmingThe drive can be programmed to perform a sequence where the drive shifts typicallythrough 1 to 8 states. User defines the operation rules for the whole sequence andfor each state. The rules of a particular state are effective when the sequenceprogram is active and the program has entered the state. The rules to be defined foreach state are:ï Run, stop and direction commands for the drive (forward/reverse/stop)ï Acceleration and deceleration ramp time for the driveï Source for the drive reference valueï State durationï RO/DO/AO statusï Signal source for triggering the shift to next stateï 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 aselected state. State change can be activated with e.g. timed functions, digital inputsand supervision functions.Sequence programming can be applied in simple mixer applications as well as inmore complicated traverse applications.The programming can be done with control panel or with a PC tool.
