Ratings and Specifications

Note: Origin Indication

The following illustration shows the relationship between phase Z and the origin. Set cut face D to the phase Z origin as shown in the illustration.

*1. An inrush current of approximately 9 A will flow for approximately 0.3 ms when the power is turned ON.

*2. The line driver output is a data transmission circuit compatible with RS-422A and long-distance transmission is possible with a twisted-pair cable.(AM26LS31

equivalent)

*3. The maximum electrical response speed is determined by the resolution and maximum response frequency as follows:

This means that the E6C2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed.

Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

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

time is lengthened and it affects the phase difference

characteristics of phases A and B. Conditions will change

according to frequency, noise, and other factors. As a guideline,

use a cable length of 10 m* or less. If the cable must be more than

2 m, use a Model with a Line-driver Output (max. length for line-

driver output: 100 m).

* Recommended Cable

Conductor cross section: 0.2 mm2

Spiral shield

Conductor resistance: 92 Ω/km max. (20°C)

Insulation resistance: 5 Ω/km min. (20°C)

•The output waveform startup time changes not only according to

the length of the cable, but also according to the load resistance

and the cable type.

•Extending the cable length not only changes the startup time, but

also increases the output residual voltage.

● Connection

Spurious pulses may be generated when power is turned ON and

OFF. Wait at least 0.1 s after turning ON the power to the Encoder

before using the connected device, and stop using the connected

device at least 0.1 s before turning OFF the power to the Encoder.

Also, turn ON the power to the load only after turning ON the power

to the Encoder.
