7.4.2 Controlling the Vacon 500x Program Sequencer
The Program Sequencer can be activated and controlled from either the keypad or the terminal strip. It is
not possible to control the sequencer through the serial link. The control method of the program sequencer
is determined by
. Setting the Input Mode parameter also allows switching from
Sequencer mode to normal keypad operation by way of the Local/Remote switch. Table 3 illustrates
possible program sequencer control configurations:.
Note: If Input Mode is configured to any of the EMOP options, the sequencer is not available.
Keypad Control (Activation) of the Vacon 500x Program Sequencer
When activating or controlling the Vacon 500x Program Sequencer from the keypad, pressing the FWD key
commands the drive to cycle through the programmed states of the sequencer one time only (one-shot
operation). One-shot operation will run the sequencer until state 25 is reached, or until any state that is
not changed from the default is reached.
Pressing the SHIFT and FWD keys simultaneously causes the programmed sequence to repeat until the
Stop key is pressed (continuous operation). In continuous mode, the sequencer runs until state 25 or any
state that is not changed from the default is reached; it then jumps back to state 1.
Note that the REV key has no function in the sequencer mode.
Terminal Control of the Vacon 500x Program Sequencer
When activating or controlling the Vacon 500x Program Sequencer from terminals, continuous and one-
shot operation is determined by whether the drive is wired for 2-wire or 3-wire control. If the terminal is
set up for 2-wire control, the sequencer operates in continuous mode (R/J terminal inactive). This will run
the sequencer until the Forward command is removed. If the terminal is set up for 3-wire control, the
sequencer runs one cycle when the FWD terminal is activated.
Note that the REV terminal has very limited function in sequencer mode. It can be used to determine
direction only when TERM/SIO is the control selection option.
