Ratings and Specifications
*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:
Maximum electrical response speed (rpm) = × 60
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°).
