When the sequencer is running, a warning, “Seq Running,” will flash on the screen to indicate that the
drive control state may change without user input. For example:
When the sequencer is dwelling (pausing) in a state, a warning, “Seq Dwell,” will flash on the screen to
indicate that the sequencer will not advance. For example:
7.4.5 Sample Sequencer Program
A machine is required to run in the forward direction at 50 Hz for one hour, then quickly decelerate to a
stop. While stopped, a digital output must be enabled to sound an alarm to an operator. After two minutes,
the machine must accelerate in the reverse direction to 5 Hz until a limit switch is activated, causing the
drive to decelerate to a stop. The following three sequential states can be programmed using only the
drive:
First, since two of the sequential states are time-based, the proper setting of the “Seq Appl” parameter
must be determined. Since there is not time required that has resolution needed of less than one second,
the “1 sec Base” option is the easiest to use. If greater resolution is needed (for example, if a state needed
to last for 2.5 seconds), another option should be chosen.
Since the sequence requires use of a digital input and a digital output, two non-sequencer parameters
need to be used. Set the parameter “DI1 Configure” to “Seq1” and the parameter “DO1 Configure” to “Se-
qOut-01.”
Since control of the sequencer is only needed from the keypad, the configuration of the “Input Mode” pa-
rameter should be “Local Only.”
Required parameter modifications for this program are provided in Table 30, with explanations.
