S3: PI2 Control

S3 parameters set the PI2 Control function. You can use this function to monitor the input, setpoint, feedback and
output levels of the PI2 Control through several additional monitors. You can also set the drive to activate certain
MFDO terminals when the PI2 feedback level is less than or more than a set value. The difference between the target
and the feedback value (deviation) is fed into the PI controller and the PI controller outputs the frequency to U5-xx for
monitoring. Refer to b5: PID Control on page 201
■
PI2 Control Setpoint and Feedback
PI2 Control has three ways to set the target setpoint. This is the order of the input setpoints from most important to
least important:
1. MEMOBUS setpoint: 000DH (while 000FH, bit 4 = 1)
2. Analog setpoint: H3-xx = 25 [MFAI Function Selection = PI2 Control Setpoint]
3. Digital setpoint: S3-05 [PI2 Control Setpoint]
For the feedback, PI2 Control only has analog setting H3-xx = 26 [PI2 Control Feedback] as the feedback level.
■
PI2 Control Monitors
These monitors will work as the PI2 Control monitors for the setpoint, feedback, input, and output:
440
V/f OLV/PM EZOLV OLV/PM
Sets the drive response when sequence timer 4 is active.
V/f OLV/PM EZOLV OLV/PM
Selects the frequency reference source to run the drive when sequence timer 4 is active (only
applicable when S2-19 > 0 [Timer 4 Sequence Selection ≠ Digital Out Only]).
