Powering Up the Drive
Review the following checklist before turning the power on.
Item to Check
Description
Power supply voltage
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.
Drive output terminals
and motor terminals
Properly wire drive output terminals U/T1, V/T2, and W/T3 with motor terminals U, V, and W.
Control circuit terminals
Check control circuit terminal connections.
Drive control terminal status
Open all control circuit terminals (off).
Status of the load
and connected machinery
Uncouple the motor from the load.

V/f Pattern Setting
Setting the V/f pattern according to the application.
Refer to E: Motor Parameters on page 86
for details on setting the
V/f pattern.
n
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.
