Multi-function Digital Input On/Off Time Delay
This function provides an On/Off Delay to all multi-function digital inputs.
When the terminal closes, the function programmed to that terminal activates after the corresponding on-delay timer elapses.
Opening the terminal will reset the on-delay timer. When the terminal opens and the function is active, the function continues
to run until the off-delay timer elapses. Closing the terminal again will reset the off-delay timer.
The on-delay and off-delay timers also affect monitor U1-10 (Input Terminal Status). The corresponding bits are set when the
function is active after the on-delay elapses. the bits are reset when the function is deactivated after the off-delay elapses. The
on-delay timer does not apply when the inputs are already closed at power-up.

PI Auxiliary Control
PI Auxiliary Control allows the drive to control pressure when the PI Auxiliary Level is adequate. When the PI Auxiliary
Control Level drops to the PI Auxiliary Control Setpoint set in Q6-03, the drive will regulate based on the PI Aux Level and
the pressure will drop.
The drive also goes to sleep, wakes up, and trips an alarm and/or fault based on the PI Auxiliary Control level.

Enable PI Aux Level Control Features
Set parameter Q6-01 to 1 to enable PI Aux Level Control and PI Aux Low Level Detection.
The drive performs PI Aux Level Control when Q6-20 is set to 1 and the drive is in PID mode (PID enabled via b5-01, not
jogging, and not disabled by other functions).
Sleep via Minimum and Maximum Levels (Q6-04 and Q6-24) apply to both Q6-20 modes.
n
Scaling and Resolution
Q6-21 sets the unit and Q6-22 sets the decimal place for the PI Aux Level parameters and monitors.

Sensing PI Aux Feedback Level
Set a multi-function analog input H3-
oo
to 27 to act as the PI Auxiliary Feedback Level and set parameter Q6-02 to the full-
scale pressure of the transducer, with units and decimal place set by Q6-21 and Q6-22. This level is displayed on the U1-96
monitor.
Wire break is detected for the PI Aux FB Level analog input when all of the following are true:
• Q6-19
≠
0 to enable PI Aux Feedback Wire-Break Detection.
• Q6-01 = 1 enabling PI Auxiliary Control.
• The multi-function analog input programmed for PI Aux FB Level (H3-
oo
= 27) is set for 4 to 20 mA operation (H3-
oo
= 2)
• The signal on the analog input falls below 3 mA or rises above 21 mA for longer than 1 second.
The drive responds based on the Q6-19 setting:
• Setting 0: Wire-break detection is disabled.
