WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use the Encoder under ambient conditions that exceed the ratings. ● Wiring Cable Extension Characteristics • When the cable length is extended, the output waveform startup • The output waveform startup time changes not only according to time is lengthened and it affects the phase difference the length of the cable, but also according to the load resistance characteristics of phases A and B. Conditions will change and the cable type. according to frequency, noise, and other factors. As a guideline, • Extending the cable length not only changes the startup time, but use a cable length of 10 m* or less. If the cable must be more than also increases the output residual voltage. 2 m, use a Model with a Line-driver Output (max. length for line- ● Connection driver output: 100 m). Spurious pulses may be generated when power is turned ON and * Recommended Cable 2 Conductor cross section: 0.2 mm OFF. Wait at least 0.1 s after turning ON the power to the Encoder Spiral shield before using the connected device, and stop using the connected Conductor resistance: 92 Ω/km max. (20°C) device at least 0.1 s before turning OFF the power to the Encoder. Insulation resistance: 5 Ω/km min. (20°C) Also, turn ON the power to the load only after turning ON the power to the Encoder.
