109 == Precautions for Main Circuit Wiring ==
110
111 ① The input power line cannot be connected to the output terminals U, V and W, otherwise the servo drive will be damaged. When using the built-in braking resistor, C and D must be connected (factory default connection).
112
113 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.
114
115 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 prone to hardening and breakage under the low temperature environment.
116
117 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.

522 The brake is a mechanism that prevents the servo motor shaft from moving when the servo drive is in a non-operating state, and keeps the motor locked in position, so that the moving part of the machine will not move due to its own weight or external force.
523
524 The brake input signal is non-polar, and the user needs to prepare 24V power supply. The standard connection diagram of brake signal BK and brake power supply is as follows:
