Chapter 5 Running and operation
5.1 Running
5.1.1 First powering on
Please check following items before power on:
1) Wiring
The power supply of the servo drive (L1, L2, L3, L1C, L2C or R, S and T) should be connect with
proper techniques; see chapter 3.2 for details;
The output phase of the servo drive (U, V and W) should be the same as that of the cables of the
servo motor;
There is no short circuit between the output of the servo drive (U, V and W) and the input power
supply (L1, L2, L3, R, S and T);
All wiring comply with the standard wiring shown in chapter 4;
Ensure the external terminal (SON) for servo enabling is set to OFF;
Ensure the servo drive and the servo motor are grounded to properly;
When using external braking resistor, for products with small power range, the short connection
cable between B2-B3 must be removed;
Do not put voltage above DC24V on CN1;
The cable stress is within the designated range.
2) Environment
There are no foreign objections, such as metal and other wire lead which can cause short
connection of signal and power wires.
3) Mechanical parts
The installation of the servo motor and the connection of shafts and mechanics are reliable;
The servo motor and the machines are available to run;
Do not run the motor at negative load (the direction of the output torque of the motor is contrary
to the motor speed direction).
If all above items are checked OK, switch on the power supply:
5.1.1.1 Sequence of powering ON/OFF
The control circuit and the main circuit of the drive are supplied separately. In principle, when
powering on, switch on the power supply of the control circuit (terminals L1C, L2C) first and then
switch on the power supply of the main circuit (terminals L1, L2, L3). When powering off, switch off the
power supply of the main circuit first and then switch off the power supply of the control circuit.
After switching on the control circuit power supply and before switching on the main circuit power
supply, R0.30 will display "0” and after power on of the main circuit, R0.30 will display "2” and the
servo drive can be enabled.
For product with medium power range (7.5kW~22kW), please connect to main circuit 3PH power (R,
S and T terminals).
