Frequently Asked Questions
How long can a servo motor encoder cable be?
+
-
Typically, the length of a servo motor encoder cable can be between 1 meter (about 3 feet) and 10 meters (about 33 feet). Cable lengths in this range can usually meet the needs of most industrial automation and mechanical applications. However, for some special applications, longer or shorter cable lengths can also be customized to meet specific requirements.
What is the minimum bending radius of the servo motor cable?

It has a special design and structure to meet high requirements for signal transmission, anti-interference and durability. It usually includes wires for power, data and feedback signal transmission, as well as possible shielding layers and insulation materials. Common interface types include M12 cable, M23 cable, etc.
Should servo motor encoder cable be shielded?
+
-
The servo motor encoder cable should be shielded because the servo system is usually used in an industrial environment and may be greatly affected by electromagnetic interference.
How does an encoder cable for a servo drive work?
+
-
The encoder cable of the servo drive is used to transmit position and speed feedback signals by connecting the encoder and the drive. Its working principle generally includes the following steps:
Encoder operation: The encoder is installed on the servo motor and converts this information into digital signals by sensing the position and speed of the motor rotor.
Signal transmission: The encoder transmits digital signals of position and speed to the servo drive through the encoder cable. The wires in the encoder cable transmit these signals from the encoder to the drive.
Drive decoding: The drive receives the signals transmitted by the encoder and controls the rotation of the motor based on these signals. The drive adjusts the rotation of the motor based on the received position and speed feedback signals to achieve precise position control and speed control.
Feedback control: The drive uses the position and speed information obtained from the encoder, compares it with the set value, and adjusts the output of the motor to ensure that the actual movement is consistent with the expected movement. This closed-loop control enables the servo system to achieve high-precision and stable motion control.
How does a servo brake work?
+
-
Servo brakes are usually electromagnetic brakes that achieve braking or release functions by controlling electromagnetic force. Its working principle is as follows:
Electromagnetic force control: The servo brake contains an electromagnetic coil inside, which generates electromagnetic force when powered. This electromagnetic force causes the brake disc inside the brake to contact the brake body fixed on the servo motor shaft, thereby achieving the braking function.
Brake release: When the brake needs to be released, the control system disconnects the power supply of the electromagnetic coil, so that the electromagnetic force disappears, and the contact between the brake disc and the brake body is also released, thereby releasing the brake.
Stability and reliability: Servo brakes are usually designed with a spring preloaded structure. Even in the event of power failure or failure, the brake will remain in the braking state, ensuring the stability and reliability of the mechanical device.
How to connect the servo motor cable?
+
-
Generally speaking, the wiring steps of the servo motor are as follows:
Confirm the power and ground cable: First, confirm the power cable and ground cable. The power cable is usually red, and the ground cable is usually brown or black. Connect the power cable to the corresponding power port and the ground cable to the ground port.
Connect the control signal: The control signal cable is generally orange, yellow, white or blue. According to the interface identification of the controller or driver, connect the control signal cable to the corresponding port.
Fix the connection: Make sure all connections are firm and reliable to avoid looseness or poor contact.
How to distinguish servo motor cables?
+
-
1. Number of encoder cables
First, the definition of the encoder cable can be distinguished by the number of servo motor encoder cables. Generally speaking, there are three or four encoder cables. If there are three encoder cables, they correspond to phase A, phase B, and phase Z, respectively, and are used to detect the phase and direction of motor rotation; if there are four encoder cables, in addition to phase A, phase B, and phase Z, there is also a power line.
2. Color of encoder cable
Secondly, the definition of the encoder cable can be distinguished by the color of the encoder cable. The colors of servo motor encoder cables of different manufacturers and models may vary slightly, but generally speaking, the color of the A phase cable is green or black, the color of the B phase cable is red or white, the color of the Z phase cable is blue or yellow, and the power line is generally red or brown. If you are not sure about the definition of the encoder cable, you can check the relevant specifications.
3. Interface of encoder cable
Finally, the definition of the encoder cable can be distinguished by the interface of the servo motor encoder cable. Generally speaking, there are two types of interfaces for encoder cables, namely terminals and plugs. If it is a terminal interface, you need to use a screwdriver to connect the cable to the terminal of the controller or drive; if it is a plug interface, you need to insert the cable into the plug of the controller or drive.
What are servo motors used for?

Servo motors are often used in applications that require precise control of position, speed, and torque, such as industrial machinery, robotics, CNC machining, etc. Servo motors can accurately adjust the position and speed of the output shaft according to the input signal, and are often used in scenarios that require high-precision motion control.
What are encoders used for?
+
-
Encoders are used to measure the position, speed and direction of motor or mechanical movement to provide accurate feedback information. In servo systems, encoders are usually used to monitor the position of the motor rotor and send feedback signals to the control system to achieve closed-loop control and ensure the accuracy and stability of the system. Encoders are also widely used in automation equipment, robots, CNC systems and other fields.
