Vacon 500x Sequencer Dwell Functionality
The Vacon 500x sequencer can dwell, or pause, in a state and disregard any command to advance to the
next state. This can be done in two different ways, and both methods can be used at the same time:
• If the sequencer is actively running and you press the Enter key on the Operate screen of
the keypad, the sequencer will dwell in the current state (it will never advance to the next
state). While the sequencer is dwelling, a warning of “Seq Dwell” will flash on the Operate
screen. To leave the dwell state, press the Enter key again from the Operate screen.
• The sequencer Dwell mode can also be entered by programming a digital input to “Seq
Dwell.” The sequencer will then dwell in the current state, for as long as the digital input
is active.
Vacon 500x Sequencer Advance Functionality
You can also allow the sequencer to advance to the next state without satisfying the conditions
programmed to advance. To do this, program a digital input to “Seq Advance.” When a digital input program
to this option changes from inactive to active, a running sequencer will advance one state. This feature is
useful when debugging a sequence with long time intervals.
7.4.3 Sequencer State Configuration Overview
Each state of the program sequencer is defined by five characteristics:
• Direction in which the drive will operate
• Speed at which the drive will operate
• Ramp selection of the drive
• Output configuration (relays and digital outputs) of the drive
• How the sequencer advances to the next state.
These characteristics are configured by two parameters for each state. These parameters are named “Seq
Cntl X” and “Seq Count X,” where X represents the state number of the sequencer. The “Seq Cntl X”
parameter is a
hexadecimal parameter that sets each of the characteristics listed above. “Seq Count X”
sets the threshold the sequencer uses to determine when to advance by the method set in the control
parameter. Bit patterns of the Seq Cntl X parameters are shown in
on the next page.
