2 Wire Control is enabled or disabled using either a Manual Parameter or switch connected to another
Digital Input. Either the Manual Parameter or the Digital Input can manually override the 2-wire control so
that the drive can be started even when the Run signal is not present. This override will not affect PLC
Analog speed control.
When you are ready to start the drive under remote 2-wire control:
• Make sure Manual Parameter 014 ManualStartOnly is set to FALSE.
• Make sure the Digital Run/Stop signal is indicating RUN.
• Take the drive out of Locked Out by pressing the Start button 1 time.
• If the system goes to Ready, you must press the Start button again. When the system goes to Restart and
starts counting down, you can either wait for the countdown or press the start button again.
The drive will now start and stop based on the Run/Stop digital input. The procedure above will need to be
repeated If the system is manually stopped or a fault occurs (for which no restarts are programmed).
5.13 Drain Mode
When Drain Mode is active, the drive will run at Frequency Setpoint2 for a fixed amount of time before
transitioning to the standard Frequency Setpoint. The feature was originally intended to allow the drive to
run at a higher frequency for a time to quickly get the intake pressure down in the desired range. However,
the
“drain” speed can be faster or slower than the standard setpoint.
To execute the wizard, from the Home Screen select
Settings -> Menu -> Other Initial Setup -> Next Page -> Next Page -> Configuration Wizards -> Next
Page -> DrainMode.
Follow the on-screen directions.
Information needed by the DrainMode wizard:
• Drain speed (Freq Setpoint2)
• Drain Complete Limit (the amount of time to run at Freq Setpoint2)
• Custom name for the drain activity. Note that the standard name is Run Mode 2, but the name can be
changed to better represent the function taking place, such as Draining.
When the wizard is complete, start the drive. The drive will accelerate and run at the Freq Setpoint2
frequency for the drain time with the drive state displaying the custom name and then transition to Running
at the standard frequency setpoint.
To disable Drain Mode, use the Advanced Triggers Config screen and disable the trigger named Drain Start.
To disable a trigger, navigate to the Trigger Info screen and press the On/Off function button.
5.14 PID Speed Control Mode
Control mode in which the drive speed is varied in an attempt to keep a system parameter (referred to as the
control parameter) at a specified level.
