YASKAWA TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup
The bypass measures the current unbalance between phases to detect input phase loss.
Sets the current level between phases in Bypass Mode.
Usually it is not necessary to change this parameter.
Sets the trip time for an input phase loss condition in Bypass Mode.
Note:
When you set this parameter to 0.0, it will disable bypass phase loss detection.
Sets bypass response when the Bypass Mode phase rotation is incorrect.
0 : Disabled
1 : Alarm
2 : Fault
Enables and disables verification that the motor is running when commanded to run.
0 : Disabled
1 : Enabled
0 : Disabled
1 : Enabled
Note:
When Z1-42 = 1 or 2 [Soft Starter Selection = Installed – Coast To Stop or Installed – Ramp To
Stop], the bypass will automatically disable welded contactor detection.
Sets the behavior of the drive input contactor K1 during Bypass Mode.
0 : Drive Power Off during Bypass
1 : Drive Power On during Bypass
Sets bypass behavior when contactor voltage is less than Z1-19 [Blackout Voltage Level].
0 : Fault
1 : Restart Delay with Speed Search
2 : Restart Delay from Zero Speed
3 : Disabled
Sets the time delay for restart.
Green Contactor Mode opens the output and motor contactors when the bypass unit is idle.
0 : Disabled
1 : Enabled
