• U5-17 [PI2 Control Setpoint]: Uses the target setpoint, which is set as specified by the setpoint source the drive will
use.
• U5-18 [PI2 Control Feedback]: Uses an analog input when H3-xx = 26 [PI2 Control Feedback].
• U5-19 [PI2 Control Input]: Input into the proportional and integral calculation as specified by the target setpoint
and feedback.
• U5-20 [PI2 Control Output]: Different for different S3-01 [PI2 Control Enable Selection] and S3-12 [PI2 Control
Disable Mode Sel] settings.
– When S3-01 > 0 [Enabled], the drive will show the calculated PI2 Control output.
– When S3-01 = 0 [Disabled], S3-12 [PI2 Control Disable Mode Sel] will set what to show.

PI2 Control Block Diagram
Figure 2.114 shows the general overview for the PI2 Control.
*1 The drive calculates the actual integral limit as:
• Upper limit = Min (S3-08, S3-09 - PI2 P portion)
• Lower limit = Min (-S3-08, S3-10 - PI2 P portion)
*2 When the MFDI set for H1-xx = A8 [MFDI Function Selection = PI2 Control Disable] is activated, you must set the PI Integrator as:
• S3-12 = 1 [Lower Limit (S3-10)]: PI Value = S3-10
• S3-12 = 2 [Setpoint]: PI Value = S3-05
