494 YASKAWA TOEPYAIHV6002A HV600 Drive Programming
The drive will not read the Network PI Aux Feedback register as the source, although the drive will still transmit its
signal to the network.
The drive will respond as specified by YF-19 .
1 : Ana->Net, No Alrm
The drive will read the Network PI Auxiliary Feedback register if the analog detection finds a signal loss through the
terminal set for
H3-xx = 27 [MFAI Function Selection = PI Auxiliary Control Feedback] . When a wire-break
detection occurs, the drive will automatically use the network value.
If the Network PI Auxiliary Feedback signal is also not valid, the drive will operate as specified by YF-19 .
Note:
When YF-19 = 0 , the drive will disable wire-break detection and will not let the drive switch to the Network PI Auxiliary Feedback.
2 : Ana->Net, Alarm
The drive will read the Network PI Auxiliary Feedback register if the analog detection finds a signal loss through the
terminal set for
H3-xx = 27 . When a wire-break detection occurs, the drive will automatically use the network value
and the keypad will show an AuFbl [PI Aux Fdbk Lost Switched to Net] alarm.
If the Network PI Auxiliary Feedback signal is also not valid, the drive will operate as specified by YF-19 .
Note:
When YF-19 = 0 , the drive will disable wire-break detection and will not let the drive switch to the Network PI Auxiliary Feedback.
3 : Network Only
The drive will always read the Network PI Auxiliary Feedback register.
If the Network PI Auxiliary Feedback signal is also not valid, the drive will operate as specified by YF-19 , with these
differences:
•
When YF-19 = 1 [Alarm Only] , the drive will show a [PI Aux Control: Net Feedback Lost] message. It will not
show an alarm.
• When YF-19 = 2 , the drive will show a [PI Aux Control: Net Feedback Lost] message, not accept Network Run
commands, and set the stopping method to coast-to-stop. It will not show a fault.

0 : Disabled
PI Aux Feedback Level does not have an effect on Idle or Lag Drives.
PI Aux Feedback Level will not cause an alternation.
1 : Enabled
The drive operation changes when YF-23 [PI Aux Ctrl Output Level Select] changes:
•
YF-23 = 0 [Direct Acting] :
When the PI Aux Control level is more than YF-06 [PI Aux Control Wake-Up Level] , a drive is offline and the
system will remove a Lag Drive.
When the PI Aux Control level is more than
YF-03 [PI Aux Control Setpoint] , the system will alternate a Lead
Drive in PI Aux Control.
•
YF-23 = 1 [Inverse Acting] :
When the PI Aux Control level is less than YF-06 , a drive is offline and the system will remove a Lag Drive.
When the PI Aux Control level is less than YF-03 , the system will alternate a Lead Drive in PI Aux Control.
