Drive Start Up Procedures
1. Confirm that all three phases are present and that the input voltage is correct for the Drive being set up.
Measure the voltage on the line side of the Drives Molded Case Circuit Breaker/disconnect and record below.
Use extreme caution when performing measurements as contact with live parts may result in personal injury
WARNING
or death.
2.
If voltage level is within Drive Specification (See Appendix C - Specification), APPLY POWER to energize the
Drive. The STOP, AUTO SEQ and AUTO REF indicators should be on.
3.
REMOVE POWER from the Drive. Wait for the Red CHARGE LED (near the power terminals)
to go out.
The internal capacitor remains charged even after the power supply is turned off. The status indicator LED's
and the digital operator display will be extinguished when the DC bus voltage is below 50VDC. To prevent
WARNING
electric shock, wait at least 5 minutes after all indicators are off and measure the DC Bus voltage level to
confirm a safe level prior to working on the Drive.
4. Connect the motor leads to the Drive at terminals U/T1, V/T2 and W/T3.
5. APPLY POWER to the Drive.
6.
Press the HAND key once. This puts the Drive in the Hand Mode, allowing run/stop and speed commands (frequency
references) by the digital operator. The AUTO SEQ and AUTO REF indicators turn off. The FWD light turns on.
The RUN light turns on. The STOP light is blinking. "Frequency Ref" (U1-01) is now displayed on the Digital Oper-
ator.
7. Press the OFF key.
8. Press the MENU key two times. Press the DATA/ENTER key once to enter the Quick Setting Menu. Press the
key 25 times to display parameter E1-01 "Input Voltage". This parameter selects the nominal input voltage the Drive
will receive. To set this parameter for the application. Press the DATA/ENTER key once. Use the
and the DATA/ENTER key to set this parameter per the application.
