Y4: Application Advanced - YASKAWA HV600 Manual

When the drive enters Sleep Mode, the software monitors the feedback to detect a flow-no flow condition. The drive
will deactivate the Sleep Mode operation and will go back to its normal operation when:
• The PID Error is more than this level in the time set in Y2-09 [Feedback Drop Detection Time]
• The output frequency is more than the level set in Y1-06 [Minimum Speed]
Note:
Set this parameter to 0.00 to disable the function.

YASKAWA TOEPYAIHV6002A HV600 Drive Programming
V/f OLV/PM EZOLV OLV/PM
Sets the time during which the software monitors the feedback to detect a flow/no-flow condition.
Refer to Y2-08 [Delta Feedback Drop Level] for more information.
V/f OLV/PM OLV/PM EZOLV
Sets the quantity of PI error bandwidth that the drive uses to detect an Anti- No-Flow condition.
V/f OLV/PM OLV/PM EZOLV
Sets the time delay before the drive starts the increased deceleration rate after it detects Anti-No-
Flow.
V/f OLV/PM OLV/PM EZOLV
Sets the amount below the setpoint which the feedback must decrease before the drive will disengage
Anti-No-Flow and return to normal PI operation.
V/f OLV/PM EZOLV OLV/PM
Sets the level at which the drive will activate the pre-charge function when the drive is running at the
frequency set in Y4-02 [Pre-Charge Frequency].
