The drive and motor must be reliably connected to ground, PE terminal must be
reliably connected to the equipment grounding end.
It is recommended that the drive power supply is provided by the isolation
transformer and power filter, to ensure the safety and anti-interference capability.
Make sure the wires are connected correct after checking, and then connect to
power.
One emergency stop circuit must be installed to ensure the power can be
immediately cut off when there is a failure (see Fig. 4-1).
After the drive alarm sounded, make sure the failure is eliminated and the SON
signal is invalid before restarting.
The drive and motor shall not be touched for at least 5 minutes after power cut off
to prevent electric shock.
The drive and motor may have a higher temperature after running for a period of
time, therefore, shall prevent burns.
4.1 Power Connection
Refer to Fig. 4-1 for power connection (three-phase 220V input), and connect the
power in the following order:
1. The power is connected to the main circuit power input end (L1, L2, and L3) through
electromagnetic contactor.
2. The power LC1 and LC2 for controlling the circuit shall be connected before or at
the same time to the main circuit power. If only connected the control circuit power,
the servo signal (S-RDY) is OFF.
3. After the main circuit power is connected, delay about 1.5 seconds, the servo signal
(S-RDY) is ON. At this time, the servo enable (S-ON) signal can be accepted, the
detected servo enable is effective, drive output is effective and motor is initiated, and
the motor is in operating state. If the servo enable detected is invalid or alarmed, the
drive inverter circuit is closed, and the motor is in free state.
4. When the servo enable is connected to power at the same time, the drive inverter
circuit is opened after about 1.5 seconds.
5. Frequent connecting and disconnecting the power may damage the soft charging
circuit and braking circuit, and the frequency of connecting and disconnecting of main
