Parker AC30 series User Manual

Fire Mode 9-3
AC30 series Variable Speed Drive
Functional Description
When Fire Mode is enabled the normal speed reference and start / stop control of the drive are modified.
Sequencing
Sequencing is the term given to controlling when the drive runs. When Fire Mode is enabled the normal sequencing control signals are over-
ridden. The parameters that control this are
Activate
Setpoint
Level
PNO 0610 Sequencing::App Control Word bit 0, Switch On, (refer to Appendix B:Sequencing Logic). In typical applications bit 0 of the App
Control Word is driven from a digital input, used as a Coast Stop signal.
If Level is set to DISABLED or Setpoint is zero then setting Activate to TRUE will have no effect.
If Level is set to either PARTIAL or FULL and Setpoint is not zero then setting Activate to TRUE will activate Fire Mode. When Fire Mode is
active the drive will run, (turn the motor).
The only reasons that the drive will not run are:
• Level is changed back to DISABLED
• Activate is changed back to FALSE
• Setpoint is change to zero
• The Coast Stop input is activated.
• The STO circuit is activated.
• An enabled trip source becomes active.
• A hardware fault
Reference
The Fire Mode Setpoint parameter is selected automatically whenever Fire Mode is Activated. The Setpoint is passed through the System
Ramp, (see Appendix D).
Caution
Fire Mode does not override the standard Ramp features. Specifically 0497 Ramp Hold can prevent the setpoint changing to
the Fire Mode Setpoint value.
