Notes when Setting the V/f Pattern
Set the maximum output frequency to match the motor characteristics.
If the V/f pattern voltage is increased motor torque may also increase. However, if the V/f voltage is set too high these problems
may occur:
• Excessive motor current.
• Motor overheat or vibration.

Ensure the power supply voltage is correct:
200 V class: single-phase 200 to 240 Vac 50/60 Hz
200 V class: 3-phase 200 to 240 Vac 50/60 Hz
400 V class: 3-phase 380 to 480 Vac 50/60 Hz
Properly wire the power supply input terminals (R/L1, S/L2, T/L3).
(for single-phase 200 V class models, wire only R/L1 and S/L2)
Check for proper grounding of drive and motor.
Properly wire drive output terminals U/T1, V/T2, and W/T3 with motor terminals U, V, and W.
Check control circuit terminal connections.
Open all control circuit terminals (off).
Uncouple the motor from the load.
