V/f OLV/PM OLV/PM EZOLV
Sets the length of time that the slave drives will wait for a message from the master before
they will show an NETSC [NETSCAN Waiting for Master] alarm.
Note:
If the network response is late or many node drives are offline, increase the value of
this parameter. The master identifies an offline drive as node 1 to Y9-25 [Highest Node
Address] that does not have a power supply, has connection problems, or is not
connected to the network.
V/f OLV/PM EZOLV OLV/PM
Sets the length of time that the network will wait before it selects and starts the Lead Drive
after the First Drive on the network is in AUTO Mode.
V/f OLV/PM OLV/PM EZOLV
Sets the gain applied to the speed of the current Lead Drive when Y9-05 = 3 [Lag Drive
Mode = Follow Lead Speed]. Set the bias to apply in Y9-31 [Lag Speed Follower Bias].
V/f OLV/PM EZOLV OLV/PM
Sets the bias applied to the speed of the current Lead Drive when Y9-05 = 3 [Lag Drive
Mode = Follow Lead Speed]. Set the gain to apply in Y9-30 [Lag Speed Follower Gain].
V/f OLV/PM EZOLV OLV/PM
Sets the deceleration time when the Y9-33 [Lag Follower Decel Activ Time] timer is
running and the drive is running as Lag Drive Speed Follower (Y9-05 = 3 [Lag Drive
Mode = Follow Lead Speed]).
V/f OLV/PM EZOLV OLV/PM
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.
Note:
Set this parameter to 0.0 to disable the function.
V/f OLV/PM EZOLV OLV/PM
Sets the low feedback level that will trigger a quick de-stage.
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.
V/f OLV/PM EZOLV OLV/PM
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.
Note:
Set this parameter to 0 to disable the function.
V/f OLV/PM OLV/PM EZOLV
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.
Note:
Set as a percentage of b5-38 [PID Unit Scaling].
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].
0 : Analog Only
1 : Ana->Net, No Alrm
2 : Ana->Net, Alarm
3 : Network Only
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
