9. Assembly steps for encoders for servo motors 9.1 Installation and zero position alignment of encoders with U.V.W
Step 1 a. Before installing the encoder, first confirm the motor's starting zero position and tighten it to ensure that the motor shaft remains stationary until the encoder is installed. Otherwise, the encoder zero position cannot be aligned with the motor zero position. b. Put the encoder (2) on the motor shaft and gently push it onto the motor platform. c. Screw in the two M3*15 bolts (3) at the same time, but do not tighten them enough to rotate the encoder by hand.
Note: For the tolerance of the encoder sleeve and the motor shaft, please refer to 8. Basic dimensions. |
|
Step 2 a. Put the wrench (A) on the slot of the encoder sleeve (outer ring), and then tighten the lock nut with the wrench (B) (the recommended tightening force is 13-16N.m). b. Connect according to the selected socket wiring table, check and power on. Please confirm again that the motor is in the zero position locked state, then turn the encoder (2) left and right by hand, and observe that the zero position signal is aligned when the LED on the encoder is on. Then tighten the two M3*15 bolts (3) and keep the LED on.
Note: *The red mark on the shaft sleeve always keeps aligned with the LED indicator *After ensuring that the lock nut is tightened, apply thread glue to the thread inside the slot to prevent the thread from loosening. *Because the zero position signal width is relatively narrow, it is easy to cause displacement during the tightening process, making the LED not light up. Please debug patiently or use other visual equipment as an auxiliary observation. |

9.2 Incremental encoder installation steps
Step 1 Put the encoder (2) on the shaft of the motor (1), gently push it to the motor platform by hand, and screw in the two M3*15 bolts (3) at the same time and tighten them.
Note: For the matching tolerance between the encoder shaft sleeve and the motor shaft, please refer to 9. Basic dimensions. |
|
Step 2 Put the wrench (A) on the slot of the encoder shaft sleeve (outer ring), and then tighten the lock nut with the wrench (B) to ensure tightening (recommended tightening force is 13-16N.m)
Note: *The red mark on the shaft sleeve is aligned with the LED indicator for the zero position primary position. When the power is turned on and the LED light is on, it is the precise zero position. *After the lock nut is tightened, apply thread glue to the thread in the slot to prevent the thread from loosening. |

Quality Control
The quality of encoders is directly related to the stability and reliability of industrial automation systems. We have built a full-process quality control system, strictly screening suppliers from raw material procurement to ensure that the performance of core components meets standards; in the production process, we use high-precision equipment and standardized processes, and cooperate with online detection technology for real-time monitoring; in the finished product stage, we conduct rigorous tests such as high and low temperature, electromagnetic compatibility, and life aging to eliminate performance risks. Each encoder has passed multiple quality inspection levels, and its excellent quality has laid a solid foundation for intelligent manufacturing, providing customers with long-term and stable use guarantees.
Application Cases
The PC58 series encoders rely on a through-shaft concentric locking device and a single-bearing ultra-thin design (thickness is only 14mm). In the field of servo motors, they achieve precise angle feedback through mechanical hard connection and a maximum resolution of 5000PPR. In robot scenarios, a variety of electrical interfaces are compatible with different control systems, and their reverse polarity/short-circuit protection improves equipment stability. The compact structure is especially suitable for installation in low spaces, meeting the miniaturization and high-precision requirements of automation equipment.
Service
I. Precautions for using the encoder
Places where the ambient temperature does not exceed the storage temperature; places where the relative humidity does not exceed the storage humidity; places where the temperature changes sharply and fogging occurs; places close to corrosive gases and flammable gases; places away from dust, salt, and metal powder; places where water, oil, and medicines are used; places where excessive vibration and impact will be transmitted to the body
II. Precautions for installing the encoder
Electrical components must not be subjected to overvoltage and other phenomena. Please conduct an electrostatic assessment of the setting environment, etc. Do not bring the motor power line close to the encoder; the FG line of the motor and the FG of the mechanical device must be reliably grounded; due to shielding The wire is not connected to the encoder body. Please make sure that the shielded wire is effectively connected to the ground at the user end.
III. Precautions on wiring
When used under the specified power supply voltage, please pay attention to the power supply voltage amplitude drop caused by the long wiring; please do not use the encoder wire and other power wires in the same pipe or bundle them in parallel; please use twisted pair wires for the signal wire and power wire of the encoder wire; please do not apply excessive force to the encoder harness, there will be a risk of disconnection
