EA180 Series Servo Drive Users Manual
3
1. Never connect the input power supply to the output terminals (U, V, W) of the servo drive.
Pay attention to the marking on the wiring terminals to ensure correct wiring! Otherwise,
the servo drive will be damaged!
2. Please ensure that the power lines comply with EMC requirements and local safety
standards. Please refer to the recommendations for the preferred wire diameter, otherwise
accidents may occur!
3. Never connect the braking resistor directly between the DC bus P + and - terminals!
Otherwise, it will cause a fire!
4. Please fasten the terminals with a screwdriver with the specified torque, otherwise a fire
may be caused.
5. Never connect a phase-shift capacitor and LC/RC noise filter to the output circuit.
6. Never connect an electromagnetic switch or magnetic contactor to the output circuit.
Otherwise, the overcurrent protection circuit of the servo drive will operate, which will
cause internal damage to the servo drive in serious cases.
7. Do not remove the connection cables inside the servo drive, otherwise it may cause internal
damage to the servo drive.
Before power-on:
1. Please confirm whether the voltage level of the input power supply is consistent with the
rated voltage level of the servo drive and whether the wiring positions on the power input
terminals (L1, L2, L3) and output terminals (U, V, W) are correct; and pay attention to
check whether there is any short circuit in the peripheral circuit connected with the servo
drive and ensure the wire connections are reliable, otherwise the servo drive may be
damaged!
2. Withstand voltage test has been performed for the product before delivery from the factory,
and it's not necessary to do it again for any part. Otherwise, an accident may be caused!
1、 The servo drive must be covered with the cover plate before being powered on, otherwise it
may cause electric shock!
2、 The wiring of all peripheral fittings must be performed correctly according to the
instructions and circuit connection method in this Manual. Otherwise, an accident may be
caused!
After power-on:
1. Do not touch the servo drive and peripheral circuits with wet hands, otherwise an electric
shock may be caused!
2. After power-on, if the indicator light is not on or the keypad displays nothing, please
disconnect the power switch immediately. Do not touch the servo drives L1, L2, L3 or any
connection terminals by hand or screwdriver, otherwise an electric shock may be caused.
After disconnecting the power switch, contact our customer service personnel
immediately.
3. At the beginning of power-on, the servo drive will automatically carry out safety detection
on the external strong current circuit. At this time, never touch the U, V, W connection
terminals of the servo drive or the motor connection terminals, otherwise an electric shock
may be caused!
