[. . . ] When connecting or disconnecting the coupling, do not impose an excessive bending, pressing, or pulling force on the E6C2-C. When connecting the shaft of the Rotary Encoder with a chain timing belt or gear, connect the chain timing belt or gear with the shaft via the bearing and coupling as shown in the following illustration. Chain sprocket Bearing Coupling E6C2-C Precautions for Safe Use Mounting Be careful not to spray water or oil onto the E6C2-C Rotary Encoder. The E6C2-C Rotary Encoder consists of high-precision components. Handle with utmost care and do not drop the Rotary Encoder, otherwise malfunctioning may result. Do not pull the cable of the E6C2-C Rotary Encoder after the E6C2C Rotary Encoder is mounted to a panel. Do not apply any shock to the hollow shaft or the body. When the E6C2-C Rotary Encoder is used in reversed operation, pay utmost attention to the mounting direction of the E6C2-C Rotary Encoder and the directions of increment and decrement rotation. To match phase Z of the E6C2-C Rotary Encoder and the origin of the device to be connected to the E6C2-C Rotary Encoder, conform the phase Z outputs while connecting the device. Be careful enough not to impose an excessive load on the shaft if the shaft connects to a gear. If the Rotary Encoder is mounted with screws, the tightening torque must be approximately 0. 5 N·m. If the Rotary Encoder is mounted to a panel, do not pull the cable with more than a force of 30 N. E6C2-C If the decentering or declination value exceeds the tolerance, an excessive load imposed on the shaft may damage the Rotary Encoder or shorten the life of the Rotary Encoder. Life of Bearing The following graph shows the life expectancy of the bearing with radial and thrust loads imposed on the bearing.

Mounting plate No shock must be given to the shaft or coupling. Therefore, do not hit the shaft or coupling with a hammer when inserting the shaft into the coupling. Refer to the following illustrations when using a standard coupling. Decentering tolerance 0. 15 mm max. 1. Do not secure the coupling and shaft with screws at this stage. Refer to the following table for the maximum insertion length of the shaft into the coupling. Model E69-C06B E69-C06M 0. 25 N·m 0. 7 N·m Tightening torque Maximum insertion length 5. 5 mm 8. 5 mm Declination tolerance 4. Be sure to turn off the Rotary Encoder when connecting the lines. Turn on the Rotary Encoder and check the output. 2° max. Displacement tolerance in the shaft direction 0. 05 mm max. 10 E6C2-C Incremental Rotary Encoder Output rise time tHL (µs) Connecting When extending the cord, select the kind of cord with care by taking the response frequency into consideration because the longer the cord is, the more the residual voltage increases due to the resistance of the cord and the capacitance between the wires. As a result, the waveform will be distorted. We recommend the line driver output type model if the cord needs to be extended.
