7.4 Using the Vacon 50X Program Sequencer
The Vacon 50X AC drive offers functionality that allows users to program up to nine independent operation
states of the drive. This functionality is called the “program sequencer” because it allows the drive to se-
quence through the operation states programmed by the user. The Vacon 50X Program Sequencer can be
used in applications that would normally require external intelligence, such as a simple programmable
logic controller.
7.4.1 Enabling the Vacon 50X Program Sequencer
The Vacon 50X Program Sequencer can be enabled with parameter 491 (Seq Appl), found in the Applica-
tion Macro programming mode of the Vacon 50X keypad. This parameter configures:
• Whether the sequencer is enabled,
• The time base used for all timing of the sequencer,
• Whether other sequencer parameters are visible in Level 2 programming.
Table 2 shows the options for this parameter:
7.4.2 Controlling the Vacon 50X 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 se-
quencer is determined by parameter 201, Input Mode. 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.
Options Value Meaning
Disabled 0
The Sequencer mode of the Vacon 50X is not active and the sequencer
parameters are not visible in Level 2 programming.
1 sec base 1
The Sequencer mode of the Vacon 50X is active, sequencer parameters are
visible in Level 2, and all timing for the sequencer will be on a 1-second base.
0.1 sec base 2
The Sequencer mode of the Vacon 50X is active, sequencer parameters are
visible in Level 2, and all timing for the sequencer will be on a .1-second
base.
0.01 sec base 3
The Sequencer mode of the Vacon 50X is active, sequencer parameters are
visible in Level 2, and all timing for the sequencer will be on a .01-second
base.
