YASKAWA TOEPYAIHV6002A HV600 Drive Programming
Description
V/f OLV/PM OLV/PM EZOLV
Sets the upper detection level for the PID feedback.
Note:
• Unit and decimal place change when the system units change.
• Range is 0.00 to 99.99 with sign-bit "+" indicating Delta to Setpoint.
V/f OLV/PM OLV/PM EZOLV
Sets the delay time between when the drive detects high feedback until the drive faults on
an HFB [High Feedback Sensed] fault.
Note:
This parameter is effective only when Y1-13 = 0 [High Feedback Selection = Fault
(and Digital Output)].
V/f OLV/PM OLV/PM EZOLV
Sets the drive response when the feedback increased to more than Y1-11 [High Feedback
Level] for longer than the time set in Y1-12 [High Feedback Lvl Fault Dly Time].
0 : Fault (and Digital Output)
1 : Alarm (and Digital Output)
2 : Digital Output Only
V/f OLV/PM OLV/PM EZOLV
Sets the hysteresis level for low and high level feedback detection.
Note:
Unit and decimal place change when the system units change.
V/f OLV/PM OLV/PM EZOLV
Sets a percentage of difference between the setpoint and the feedback. The difference must
be more than this value for the time set in Y1-16 [Not Maintaining Setpoint Time] to
trigger the drive response set in Y1-17 [Not Maintaining Setpoint Sel].
Note:
• Unit and decimal place change when the system units change.
• If there is a fault, the drive will coast to a stop.
• Set this parameter to 0.0 to disable the function.
• This function is only active during run when in Auto Mode.
• When Y1-01 = 3 [Multiplex Mode = Memobus Network], the function is active on
the lead drive, but will stop all drives running on the network if there is an NMS
[Setpoint Not Met] fault (system fault).
V/f OLV/PM EZOLV OLV/PM
Sets the delay time before a Setpoint Not Met condition occurs. The drive must detect the
setpoint difference set in Y1-15 [Maximum Setpoint Difference] before the timer will start.
Note:
Set Y1-15 = 0 [Maximum Setpoint Difference = 0] to disable this function.
V/f OLV/PM OLV/PM EZOLV
Sets the drive response when the feedback increases to more or decreases to less than the
setpoint for more than the amount set in Y1-15 [Maximum Setpoint Difference].
0 : Fault (and Digital Output)
1 : Alarm (and Digital Output)
2 : Digital Output Only
V/f OLV/PM EZOLV OLV/PM
Sets the units and quantity that the drive will use to determine LOP [Loss of Prime].
0 : Current (A)
1 : Power (kW)
2 : Torque (%)
V/f OLV/PM OLV/PM EZOLV
Sets the level to detect the LOP [Loss of Prime] in the pump when in Auto or Sleep Boost
Mode.
V/f OLV/PM OLV/PM EZOLV
Sets the delay time before the drive detects an LOP [Loss of Prime] condition. The timer
starts when the drive detects the conditions in Y1-18 [Prime Loss Detection Method] and
Y1-19 [Prime Loss Level].
V/f OLV/PM EZOLV OLV/PM
Sets the frequency level above which the drive enables Loss of Prime detection.
V/f OLV/PM EZOLV OLV/PM
Sets the drive response when the drive is in the Loss of Prime condition.
0 : Fault (and Digital Output)
1 : Alarm (and Digital Output)
2 : Digital Output Only
