The use of the external zeroing line (gray) : When the equipment needs to find the zero point or recalibrate the zero position, please short-circuit the gray line to the 24V power supply for 3 to 5 seconds. After the time is reached, please remove the gray line. This is when the encoder defaults to the zero point of this position. |

Service
1. Precautions for Using Encoders
A place where the ambient temperature must not exceed the storage temperature; A place where the relative humidity must not exceed the storage
humidity; It cannot be in places with sharp temperature changes and fogging. Places close to corrosive gases and flammable gases; Stay away from
places with a lot of dust, salt and metal powder. Stay away from places where water, oil and medicine are used; Excessive vibration and shock can be
transmitted to the main body
2. Precautions for Installing Encoders
Electrical components must not be subjected to overvoltage or other phenomena. Please conduct static electricity assessment of the setting
environment, etc. Do not allow the motor power line to approach the encoder. The FG wire of the motor and the FG wire of the mechanical device
must be reliably grounded. Since the shielded wire is not connected to the encoder body, the shielded wire must be effectively connected to the
ground at the user end
3. Precautions on Wiring
When used at the specified power supply voltage, please pay attention to the decrease in power supply voltage amplitude caused by the long wiring.
Please do not use the encoder line and other power lines in the same pipe or bundle them in parallel. Please use twisted-pair wires for the signal line
and power line of the encoder. Please do not apply excessive force to the wire harness of the encoder, as there is a risk of wire breakage
