Do not apply direct impact to the shaft during installation.
The connection between the servo motor encoder shaft and the machine should use flexible connectors. When attaching connectors to the shaft, do not press them in. Even if a connector is used, it is necessary to be careful that a load greater than the allowable load may be applied to the shaft due to poor installation, or the phenomenon of dialing the core.
Bearing life is related to the conditions of use and is particularly affected by bearing load. If the bearing load is smaller than the specified load, the bearing life can be greatly extended.
Do not disassemble the encoder, as this will compromise oil and drip resistance. Anti-drip products should not be soaked in water for a long time, and should be wiped clean when there is water and oil on the surface.
Vibration
Vibrations applied to the encoder are often the cause of false pulses. Therefore, attention should be paid to the installation site and installation site. The greater the number of pulses per revolution, the narrower the slot spacing of the rotating groove disc and the more susceptible it is to vibration. When rotating or stopping at low speeds, vibrations applied to the shaft or body cause the rotating groove disc to shake, and false pulses may occur.
Wiring connections
(1) Wiring should be done with the power supply OFF, and if the output line is in contact with the power supply when the power is turned on, the output circuit may be damaged.
(2) If the wiring is incorrect, the internal circuit may be damaged, so pay full attention to the polarity of the power supply when wiring.
(3) If it is wired in parallel with the high-voltage line and power line, it may be damaged by malfunction caused by induction, so it should be separated and wired separately.
(4) When extending the wire, it should be less than 10m. In addition, due to the distribution capacity of the wire, the rise and fall time of the waveform is long, and when there is a problem, the waveform is shaped using a Schmidt circuit, etc.
(5) In order to avoid inductive noise, etc., use the shortest distance for wiring. Special attention is required when inputting into an integrated circuit.
(6) When the wire is extended, due to the influence of conductor resistance and inter-line capacitance, the rise and fall time of the waveform is lengthened, and it is easy to produce interference between signals (crosstalk), so wires with small resistance and low capacitance between wires (twisted pair and shielded wires) should be used.
