•
U5-19 [PI2 Control Input]
: Input into the proportional and integral calculation as specifed 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.

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
