YASKAWA TOEPYAIHV6002A HV600 Drive Programming
Description
V/f OLV/PM OLV/PM EZOLV
Sets how to select the new Lead Drive.
Note:
• When Y9-01 = 1, MEMOBUS network uses monitor U4-01 [Cumulative Ope Time].
The settings of o4-01 [Elapsed Operating Time Setting] and o4-02 [Elapsed
Operating Time Selection] will have a direct effect on this parameter.
Yaskawa recommends to keep o4-02 = 1 [U4-01 Shows Total RUN Time].
• When U4-01 > 65535 hours, alternation timer has reached its maximum value.
Yaskawa recommends to reset the runtime hours (o4-01) on all the drives to keep the
function working correctly.
0 : Next Available
1 : Lowest Runtime
2 : Stop History
V/f OLV/PM OLV/PM EZOLV
Sets the signal to use for PID Feedback when Y1-01 = 3 [Multiplex Mode = Memobus
Network].
0 : Analog Only
1 : Ana->Net, No Alarm
2 : Ana->Net, Alarm
3 : Network Only
V/f OLV/PM OLV/PM EZOLV
Sets how much time a drive will request for the alternation, which is set in Y9-04
[Alternation Mode].
Note:
• Parameter Y9-19 [Alternation Time Unit] sets the unit text.
• Set this parameter to 0 to disable the alternation function.
V/f OLV/PM EZOLV OLV/PM
Sets how the drive does alternation.
Note:
You can use this parameter only when Y1-03 = 3 [Multiplex Mode = Memobus
Network].
0 : FIFO Auto
1 : FIFO Forced
2 : LIFO
3 : FIFO @Sleep
V/f OLV/PM EZOLV OLV/PM
Sets the function of the Lag Drives.
0 : Fixed Speed
2 : Turn Off
3 : Follow Lead Speed
V/f OLV/PM EZOLV OLV/PM
Sets the speed at which the drive will run when the drive set in Y9-05 = 0 [Lag Drive
Mode = Fixed Speed] changes from a lead to a lag and the time set in Y9-07 [Lag Fixed
Speed Delay] is expired.
V/f OLV/PM OLV/PM EZOLV
Sets how long the drive holds its current speed before the drive operates as specified in Y9-
05 [Lag Drive Mode] when the drive changes from a Lead to a Lag and Y9-05 ≠ 1 [Fixed
Speed].
V/f OLV/PM OLV/PM EZOLV
Sets the method to determine when it is necessary to stage a new drive to keep the setpoint.
0 : Output Frequency
1 : Feedback
2 : Feedback + Fout
V/f OLV/PM EZOLV OLV/PM
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.
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.
