Y9-33: Lag Follower Decel Activ Time
No.
Name
(Hex.)
Y9-33 Lag Follower Decel Activ
Time
(3E14)
RUN
Note:
Set this parameter to 0.0 to disable the function.
■
Y9-34: Low Feedback De-stage
No.
Name
(Hex.)
Y9-34 Low Feedback De-stage
(3E15)
RUN
Note:
• 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.
• The quick de-stage ignores Y9-12 [De-staging Mode] and Y9-15 [De-staging Delay Time] and only uses an internal 2 s delay.
• Set this parameter to 0.00 to disable the function.
■
Y9-35: Alternation Stabilize Time
No.
Name
(Hex.)
Y9-35 Alternation Stabilize Time
(3E16)
RUN
Note:
Set this parameter to 0 to disable the function.
■
Y9-36: Alternation Stabilize Bias
No.
Name
(Hex.)
Y9-36 Alternation Stabilize Bias
(3E17)
RUN
Note:
Set as a percentage of b5-38 [PID Unit Scaling].
■
Y9-50: PI Auxiliary Control Source
No.
Name
(Hex.)
Y9-50 PI Auxiliary Control Source
(3E25)
Note:
• Drives that have YF-19 = 0 [PI Aux Ctrl Feedback WireBreak = Disabled] and Y9-50 ≠ 3 will have wire-break detection and will
continuously send valid or invalid PI Aux Feedback signals to the Network.
• When YF-19 = 2 [Fault (no retry, coast to stop)] and Y9-50 ≠ 3, the PI Auxiliary Feedback detection will cause an alarm(not a fault) when
one of these conditions is true:
–The drive is in HAND Mode
–There is no Lead Drive on the network
–The drive is not in AUTO Mode
0 : Analog Only
YASKAWA TOEPYAIHV6002A HV600 Drive Programming
V/f OLV/PM OLV/PM EZOLV
Sets the time during which the deceleration time set in Y9-32 [Lag Follower Deceleration Rate] is
effective. The drive will use the standard deceleration rate when it is expired.
V/f OLV/PM OLV/PM EZOLV
Sets the low feedback level that will trigger a quick de-stage.
V/f OLV/PM OLV/PM EZOLV
Sets the maximum length of time the drive will stay running after it is called to alternate-out. The
drive will be in Alternation Stabilization Mode during this time.
V/f OLV/PM EZOLV OLV/PM
Sets the minimum quantity of PID error applied to the drive during Alternation Stabilization Mode. A
lower value can cause it to stay running longer, while a higher value will make the change faster, but
it will have a larger pressure change.
V/f OLV/PM EZOLV OLV/PM
Sets the signal to use for PI Auxiliary Control [YF-xx] when Y1-01 = 3 [Multiplex Mode = Memobus
Network].
