4.1.3 Precautions for main circuit wiring
1
Do not connect the input power cord to the output terminals U, V, W, otherwise the servo
drive will be damaged. When using the built-in braking resistor, C and D must be connected (factory
default connection).
2
When the cables are bundled and used in pipes, etc., due to the deterioration of heat
dissipation conditions, please consider the allowable current reduction rate.
3
When the temperature in the cabinet is higher than the cable temperature limit, please choose
a cable with a larger cable temperature limit, and it is recommended that the cable wire use Teflon
wire. Please pay attention to the warmth of the cable in the low temperature environment.
Generally, the surface of the cable is easy to harden and break under the low temperature
environment.
4
The bending radius of the cable should be more than 10 times the outer diameter of the cable
itself to prevent the core of the cable from breaking due to long-term bending.
