Full-Voltage Reversing Starter
Full-voltage reversing starter motor applications require the following settings:
• TWO SPEED ENABLE = Y (Yes)
• IN1 = 0 0 0 0 0 0 0 1 0 0 (Speed 2)
• FVR PHASING = the phase (A, B, or C) that is not changing
• CT RATIO-2nd = CT RATIO
• MOTOR FLA-2nd = MOTOR FLA
• MOTOR LRC-2nd = MOTOR LRC
• MOTOR LRT-2nd = LOCKED ROTOR TIME
• ACCEL FACT-2nd = ACCEL FACTOR
• RUN ST TC-2nd = RUN STATE TIME K
