YASKAWA TOEPYAIH6B01A HV600 AC Drive Narrow Bypass Installation & Startup
Causes
You are driving a general-purpose motor below the
rated speed with a high load.
Causes
Input power is too low.
The brownout settings are incorrect.
Causes
Input power is too low.
The blackout settings are incorrect.
Causes
The cable between the bypass controller and the drive
is disconnected or damaged.
The bypass controller circuit is defective.
The drive circuitry is defective.
Causes
The motor is disconnected from the drive
The load is disconnected from the motor.
The Loss of Load settings are incorrect.
Causes
Bypass Mode current unbalance condition is more
than the unbalance level limit in Z1-50 for the length
of time in Z1-51.
Causes
Incorrect phase rotation while Z1-52 = 2 in Bypass
Mode.
Causes
The drive or bypass output current is less than 5% of
E2-01, Motor Rated Current for longer than 10
seconds.
Causes
The bypass detected a welded contactor condition.
Possible Solutions
• Decrease the load
• Increase the speed
• If the motor is designed to operate at low speeds, increase the
motor capacity or use a motor designed to operate in the desired
speed range.
Possible Solutions
Make sure that the input power is sufficient to power the bypass.
Make sure that Z1-27 [Brownout Voltage Level] and Z1-28
[Brownout Time] are correct.
Possible Solutions
Make sure that the input power is sufficient to power the bypass.
Make sure that Z1-29 [Blackout Voltage Level] is correct.
Possible Solutions
Make sure that the cable between the bypass controller board (A2)
connector CN6 to drive terminal TB4 is connected at both ends and
is not damaged.
Replace the bypass control board.
Replace the drive.
Possible Solutions
Check the continuity between the drive/bypass and the motor.
Check the belt/coupling between the motor and the load
Make sure that the settings in Z1-31 to Z1-36 are correct.
Possible Solutions
• Make sure that the input wiring including fuses, breakers, and
connections upstream from the bypass is correct.
• Make sure that the motor wiring and connections are correct.
Possible Solutions
Make sure that the sequence (phase rotation) of the input wiring to
the bypass package is correct.
Possible Solutions
• Close all external output disconnects.
• Make sure that the frequency reference or PID ≠ 0.
• Set d2-02 > 0.0%
Possible Solutions
Inspect the contactor.
