Using the X5 Program Sequencer
The X5 AC drive offers functionality that allows users to program up to 25 independent operation
states of the drive. This functionality is called the “program sequencer” because it allows the drive
to sequence through the operation states programmed by the user. The X5 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 X5 Program Sequencer
The X5 Program Sequencer can be enabled with
491
(Seq Appl)
, found in the Application
Macro programming mode of the X5 keypad (see
for more information on the macro
programming mode). 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 7-3 shows the options for this parameter:
