Start-Up 4 - 5Drive 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 Drive’s Molded Case Circuit Breaker/disconnect and record below.
2. If the voltage level is within the Drive’s specification, APPLY POWER to energize the Drive. The STOP, AUTOSEQ and AUTO REF indicators should be lit on the keypad.
3. REMOVE POWER from the Drive. Wait for the Red CHARGE LED (near the power terminals)to go out.
4. Connect the motor leads to the Drive at terminals U/T1, V/T2 and W/T3.
5. APPLY POWER to the Drive.
6. Determine the proper control method for the application: V/F Control, V/F with PG Control, Open Loop Vector, orFlux Vector Control.
7. If the selected control method requires a PG encoder on the motor (V/F with PG Control and Flux Vector Control),verify that the proper PG card is installed in the Drive and that all encoder wiring is correct. Check the line driver type(8830, 88C30), output levels, quadrature (A+, A-, B+, B-, etc.), and encoder PPR (pulses per revolution). Refer toChapter 2 - Electrical Installation for details.
