Sequencer Output Configuration
The Vacon 50X Program Sequencer allows digital outputs to be activated during states of the sequencer.
This function could be used to activate other devices in a system or to signal to an operator when a part
of the sequence is active. The user sets the digital output by setting bits 9 and 10 of the control parameter
with a binary value, and then sets a digital output parameter with the option for that same binary value.
For example, if a control state was output configured for a binary value of 11, then any digital output con-
figured to “SeqOut-11” would be activated during that time.
Sequencer Direction Selection
The sequencer allows each state to be configured as running Forward, Reverse, Stopped, or DC Injected
by setting bits 7 and 8 of the control parameters.
Sequencer State Duration
Bits 4, 5, and 6 of each sequencer control parameter specify how that step will allow advancement to the
next step. The options for advancement are time, pulse input, voltage threshold, current threshold, or
digital input comparison. After the advancement method is selected with these bits, the threshold of ad-
vancement is determined by the state’s count parameter (see the next paragraph).
Sequencer State Advance Threshold (via Count Parameter)
The sequencer count parameters work in conjunction with the state duration configuration in the control
parameter to determine when to advance to the next state. The function of this parameter is dependent
on the state duration configuration as defined in Table 6 on page 96. The range of data programmed into
this parameter can be from 0 to 65,535, and can represent time, pulse counts, analog voltage thresholds,
analog current thresholds, or digital comparison values.
