4.3 Start-up, Test Operation, and Rotation Check
128 YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference
3. Check the lower-left corner of the keypad screen to make sure that the bypass is in Drive Mode. “DRIVE” will
flash when the bypass is in Drive Mode.
WARNING! Sudden Movement Hazard. Before you do the next step, remove all personnel and objects from the area
around the bypass and motor. The motor will rotate in the next step and can cause serious injury or death.
4. Push to give the bypass a Run command from HAND Mode.
5. Push to show S5-05 [HAND Frequency Reference], and set it to 6.00 Hz.
6. Push to save the value and the motor will start to run.
If the system does not run, check the keypad for a “Safety Open” message or an “AL02 – Interlock Open”
alarm.
• If there is a “Safety Open” message, check the safety circuit (or jumper) connected at TB2-2.
• If there is an “AL02 – Interlock Open” alarm, check the BAS Interlock circuit (or jumper) connected at TB2-3.
7. Push to return to the HOME screen, then push until you can see the Output Current display on the
keypad screen.
Output current should typically be between 20% and 100% of motor full load amps (FLA).
If the output current is not in this range:
• Make sure that there are no mechanical issues or binding in the machinery.
• Make sure that the motor is correctly wired to the motor terminal block (or motor overload, if equipped).
• Make sure that a multi-voltage motor is correctly wired in the motor junction box.
8. Look at the motor (or load) to make sure that the rotation direction is correct (Drive Mode).
If the motor direction in Drive Mode is CORRECT, do steps 15 to 18.
If the motor direction in Drive Mode is INCORRECT, do steps 9 to 14.
9. Push to stop the motor.
10. De-energize the system at the power source. Observe correct lockout/tagout safety procedures and wait for
the CHARGE light to completely go out on the HV600.
11. Remove lower cover (or open cabinet door) to access motor wiring.
