Q6-23: PI Auxiliary Control
Determines whether the PI Auxiliary Controller is Direct-acting (feedback higher than setpoint results in lower speed) or
Inverse-acting (feedback lower than setpoint results in lower speed).
No.

PI Auxiliary Control
0, 1

Setting 0: Direct Acting
When Q6-25 (PI Aux Control Activation Level) = 0, the PI Aux Controller can affect the output frequency if the controller’s
output is less than the primary PID (System Pressure) controller’s output.
When Q6-25 (PI Aux Control Activation Level) > 0, the PI Aux Feedback Level (H3-
oo
= 27) has to rise above the level
set in Q6-25 for the time set in Q6-26 (PI Aux Control Activation Delay) before the PI Aux Controller is allowed to affect the
output frequency.
When active, the PI Aux Feedback Level (H3-
oo
= 27) has to drop below the Q6-25 level for the time set in Q6-26 before
the PI Aux Controller is deactivated and not allowed to affect the output frequency.
Setting 1: Inverse Acting
When Q6-25 (PI Aux Control Activation Level) = 0, the PI Aux Controller can affect the output frequency if the controller’s
output is less than the primary PID (System Pressure) controller’s output.
When Q6-25 (PI Aux Control Activation Level) > 0, the PI Aux Feedback Level (H3-
oo
= 27) has to drop below the level
set in Q6-25 for the time set in Q6-26 (PI Aux Control Activation Delay) before the PI Aux Controller is allowed to affect the
output frequency.
When active, the PI Aux Feedback Level (H3-
oo
= 27) has to rise above the Q6-25 level for the time set in Q6-26 before
the PI Aux Controller is deactivated and not allowed to affect the output frequency.

S2-01/S2-06/S2-11/S2-16: Sequence Timers 1 to 4 Start Time
Sets the start times for timers 1 to 4.
If the Stop Time is set to a higher value than the Start Time, the Sequence Timers will be active starting from the set Start
Time, run through midnight, and stop the following day at the set Stop Time.
Note:
Setting the sequence timer start time to a higher value than the sequence timer stop time disables that sequence timer in drive software
versions PRG: 8551 and earlier.
