Y9-09: Staging Frequency Level
No.
Name
(Hex.)
Y9-09 Staging Frequency Level
(3DFC)
RUN
Note:
• When A1-02 = 8 [Control Method Selection = EZOLV], the range is 0.0 - 120.0 Hz.
• Parameter Y9-08 [Staging Mode] sets the condition to request for a new Lead Drive.
–Y9-08 = 0 [Output Frequency]: The output frequency must increase to more than this level for the time set in Y9-11 [Staging Delay Time]
to request for a new Lead Drive.
–Y9-08 = 2 [Feedback + Fout]: The delta feedback (setpoint minus feedback) must be more than Y9-10 [Staging Delta Feedback Level]
level for the time set in Y9-11 [Staging Delay Time] and the output frequency must increase to more than this level to request for a new
Lead Drive.
■
Y9-10: Staging Delta Feedback Level
No.
Name
(Hex.)
Y9-10 Staging Delta Feedback
Level
(3DFD)
RUN
Note:
• When b5-09 = 0 [PID Output Level Selection = Normal Output (Direct Acting)], the drive uses the setpoint minus the feedback to
determine the delta feedback level.
• When b5-09 = 1 [Reverse Output (Reverse Acting)], the drive uses the feedback minus the setpoint to determine the delta feedback level.
• Parameter Y9-08 [Staging Mode] sets the condition to request for a new Lead Drive:
–Y9-08 = 1 [Feedback]: The difference between the setpoint and feedback must increase to more than this level for the time set in Y9-11
[Staging Delay Time] to request for a new Lead Drive.
–Y9-08 = 2 [Feedback + Fout]: The difference between the setpoint and feedback must increase to more than this level and the output
frequency must be more than Y9-09 [Staging Frequency Level] for the time set in Y9-11 [Staging Delay Time] to request for a new Lead
Drive.

RUN
■
Y9-12: De-staging Mode
No.
Name
(Hex.)
Y9-12 De-staging Mode
(3DFF)
0 : Output Frequency
The drive monitors the output frequency of the Lead Drive.
When the output frequency < Y9-13 [De-staging Frequency Level] for the time set in Y9-15 [De-staging Delay Time]
and when this drive is not the only drive running, the Lead Drive will send a de-stage request.
1 : Feedback
The drive monitors the feedback level of the Lead Drive.
When the difference between the feedback and the setpoint is more than Y9-14 [De-staging Delta Feedback Level] for
the time set in Y9-15 and when this drive is not the only drive running, the Lead Drive will send a de-stage request.
2 : Feedback + Fout
488
V/f OLV/PM OLV/PM EZOLV
Sets the level above which the output frequency must increase before the Lead Drive will send a
request for a new Lead Drive through the MEMOBUS network.
V/f OLV/PM OLV/PM EZOLV
Sets the level above which the difference between the setpoint and feedback must increase before the
lead drive will send a request for a new Lead Drive through the MEMOBUS network.
V/f OLV/PM EZOLV OLV/PM
Sets the delay time before adding a new Lead Drive to the system.
V/f OLV/PM EZOLV OLV/PM
Sets the method to determine when it is necessary to de-stage the previous Lead Drive to keep the
setpoint.
