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.
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.
V/f OLV/PM EZOLV OLV/PM
Sets the delay time before adding a new Lead Drive to the system.
V/f OLV/PM OLV/PM EZOLV
Sets the method to determine when it is necessary to de-stage the previous Lead Drive to
keep the setpoint.
0 : Output Frequency
1 : Feedback
2 : Feedback + Fout
V/f OLV/PM EZOLV OLV/PM
Sets the level below which the output frequency must decrease before the Lead Drive will
request to be removed from the system through the MEMOBUS network.
Note:
• When A1-02 = 8 [Control Method Selection = EZOLV], the range is 0.0 - 120.0 Hz.
• Parameter Y9-12 [De-staging Mode] sets the condition to request for the removal:
–Y9-12 = 0 [Output Frequency]: The output frequency must decrease to less than
this level for the time set in Y9-15 [De-staging Delay Time] to request for the
removal.
–Y9-12 = 2 [Feedback + Fout]: The output frequency must decrease to less than this
level and the difference between the feedback and setpoint must be more than Y9-14
[De-staging Delta Feedback Level] for the time set in Y9-15 [De-staging Delay
Time] to request for the removal.
V/f OLV/PM EZOLV OLV/PM
Sets the level above which the difference between the feedback and setpoint must increase
before the lead drive will request to be removed from the system through the MEMOBUS
network.
Note:
• When b5-09 = 0 [PID Output Level Selection = Normal Output (Direct Acting)], the
drive uses the feedback minus the setpoint to determine the delta feedback level.
• When b5-09 = 1 [Reverse Output (Reverse Acting)], the drive uses the setpoint
minus the feedback to determine the delta feedback level.
• Parameter Y9-12 [De-staging Mode ] sets the condition to request for the removal:
–Y9-12 = 1 [Feedback]: The difference between the feedback and setpoint must
increase to more than this level for the time set in Y9-15 [De-staging Delay Time] to
request for the removal.
–Y9-12 = 2 [Feedback + Fout]: The difference between the feedback and setpoint
must increase to more than this level and the output frequency must be less than Y9-
13 [De-staging Frequency Level] level for the time set in Y9-15 [De-staging Delay
Time] to request for the removal.
• Parameters b5-46 [PID Unit Display Selection], b5-38 [PID User Unit Display
Scaling], and b5-39 [PID User Unit Display Digits] set the unit, range, and
resolution.
V/f OLV/PM EZOLV OLV/PM
Sets the delay time before removing the Lead Drive from the system.
V/f OLV/PM OLV/PM EZOLV
Sets the time used to keep the system stable when you stage or de-stage a drive.
Note:
Lead-lag control and pump protection is stopped during the stabilization time.
V/f OLV/PM EZOLV OLV/PM
Sets the value by which the system setpoint is incremented as specified by the number of
drives that are running.
