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.
5.2 Powering Up the Drive and Operation Status Display
Power Up
Check the following table before applying the power supply.
Table 5.2.1 Check List before Power Up
Check Power supply voltage
Properly wire the power input terminals R/L1, S/L2 and T/L3.
Ensure proper grounding of AC drive and motor.
Status of drive output terminals
and motor terminals
Ensure the drive output terminals (U/T1, V/T2 and W/T3) are wired
properly with motor terminals (U, V and W).
Status of control circuit terminals
Ensure the drive control circuit terminals are wired properly with
other control device.
Status of drive control terminals
Ensure all the drive control circuit terminals are open.
Status of the load and connected
machinery
Check if the motor is connected to the machinery.
