5.1 Check before Operation

Make sure the main circuit is properly wired. R/L1, S/L2 and T/L3 are power input

terminals which cannot be mixed with U/T1, V/T2, W/T3. Failure to comply could cause
damage to the AC drive.
Make sure the ground terminal is properly wired.

Make sure the drive capacity matches the related parameter settings.

Do not use the drive with wet hands.

Check the connected machinery status before Auto-Tuning to ensure personnel safety.

Drives could increase the motor speed rapidly. Ensure appropriate speed tolerance for the

motor and machinery.
When using options such as a braking unit, always follow its instructions.

Drives can only operate in environment with -10℃ to +50℃, below 90% RH and free from

condensation, metal shavings or liquid.

Table 5.2.1 Check List before Power Up
400 V : Three-phase AC 380 V to 480 V, 50/60 Hz
Properly wire the power input terminals R/L1, S/L2 and T/L3.
Ensure proper grounding of AC drive and motor.
Ensure the drive output terminals (U/T1, V/T2 and W/T3) are wired
properly with motor terminals (U, V and W).
Ensure the drive control circuit terminals are wired properly with
other control device.
Ensure all the drive control circuit terminals are open.
Check if the motor is connected to the machinery.
