Wiring
1
The main circuit input terminals (L1, L2) of the servo drive must be connected
correctly.
2
The main circuit output terminals (U, V, W) of the servo drive and the main circuit
cables (U, V, W) of the servo motor must have the same phase and be connected
correctly.
3
The main circuit power input terminals (L1, L2) and the main circuit output terminals
(U, V, W) of the servo drive cannot be short-circuited.
4
The wiring of each control signal cable of the servo drive is correct: the external signal
wires such as brake and overtravel protection have been reliably connected.
5
Servo drive and servo motor must be grounded reliably.
6
When using an external braking resistor, the short wiring between drive C and D must
be removed.
7
The force of all cables is within the specified range.
8
The wiring terminals have been insulated.
Environment and Machinery
1
There is no iron filings, metal, etc. that can cause short circuits inside or outside the
servo drive.
2
The servo drive and external braking resistor are not placed on combustible objects.
3
The installation, shaft and mechanical structure of the servo motor have been firmly
connected.

6.1.2 Power on
(1) Connect the main circuit power supply
After switching on the main circuit power supply, the bus voltage indicator shows no abnormality,
and the panel display "rdy", indicating that the servo drive is in an operational state, waiting for
the host computer to give the servo enable signal.
If the drive panel displays other fault codes, please refer to [
] to analyze and
eliminate the cause of the fault.
(2) Set the servo drive enable (S-ON) to invalid (OFF)
6.1.3 Jog operation
Jog operation is used to judge whether the servo motor can rotate normally, and whether there is
abnormal vibration and abnormal sound during rotation. Jog operation can be realized in two ways,
one is panel jog operation, which can be realized by pressing the buttons on the servo panel; the
other is jog operation through the host computer debugging platform.
