Instruction manual
 Note: Coupling, mounting bracket and hex-head spanner are sold separately.

1. An inrush current of approximately 9 A will flow for approximately 0.1 ms when the power is turned ON.
 2. Complementary Output The complementary output has two output transistors (NPN and PNP) as shown below. These two output transistors alternately turn ON and OFF depending on the high or low output signal. When using them, pull up to the positive
 power supply voltage level or pull down to 0 V. The complementary output allows flow-in or flow-out of the output current and thus the rising and falling speeds of signals are fast. This allows a long cable distance. They can be connected to open-collector input devices (NPN, PNP).

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

image

This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed.
 5. The phase Z signal is output when cut face D on the shaft and the cable connection direction are as shown in the following diagram (output position range: ±15°).
