Y4-42: Output Disconnect Detection Sel
No.
(Hex.)
Name Description
Default
(Range)
Y4-42
(3D23)
Output Disconnect Detection
Sel This parameter applies only when in Drive Mode. It sets the drive response if the connection between
the drive and the motor is disconnected. 0
(0 - 3)
Note:
1. Loss Of Load [Z1-31 to Z1-36] , Load Verify [Z1-53] , and Bypass Energy Savings [Z1-16] can interfere with the correct operation of
Output Disconnect Detection.
2. When the Output Disconnect is active, the drive internally disables Output Phase Loss Detection of more than one phase.
0 : Disabled
1 : Alarm - Speed Search
The drive will show an OD [Output Disconnect] alarm. When you close the output again, the drive will do a
baseblock and a Speed Search for the correct recovery.
Note:
If at any time the customer Run command is removed, the drive will clear the OD alarm and enter a normal stopped state.
2 : Alarm - Start at Zero
The drive will show an OD alarm. When you close the output again, the drive will do a baseblock and let the soft-
starter to ramp up from zero for the correct recovery.
Note:
If at any time the customer Run command is removed, the drive will clear the OD alarm and enter a normal stopped state.
3 : Fault
The drive will coast to stop and show an OD [Output Disconnect] fault.
Note:
You cannot Auto-Restart the drive after an OD fault.
■
Y4-43: Output Disconnect Inject Current
No.
(Hex.)
Name Description
Default
(Range)
Y4-43
(3D24)
Output Disconnect Inject
Current Sets the level of DC injection current during output disconnect as a percentage of the drive rated
current. 30%
(5 - 50%)

YA: Preset Setpoint
■
Setpoint Selection
Parameters YA-01 [Setpoint 1] to YA-04 [Setpoint 4] set the PID setpoint.
The priority over PID setpoint changes when the settings of MFDI functions
H1-xx = 3E and 3F [PID Setpoint
Selection 1 and 2] change. Table 5.67 shows how the different MFDI functions ( H1-xx = 3E and 3F [PID Setpoint
Selection 1 and 2] ) have an effect on the PID setpoint value.
Table 5.67 Switching of MFDI and PID Setpoint Value
H1-xx = 3E H1-xx = 3F PID Setpoint Value
OFF OFF
One of these values:
• Frequency Reference (determined by b1-01 [Frequency Reference Selection 1] )
• YA-01 [Setpoint 1] (when b1-01 = 0 [Keypad] )
• Analog Setpoint (when H3-xx = C [MFAI Function Selection = PID Setpoint] )
• MEMOBUS setpoint
