2. LINEAR SCALES
Connection cable connection example
Note 1. The A/B/Z-phase differential input interface unit is required to use the A B Z-phase differential output linear scale.
2. If there is no Z phase, an alarm occurs and operation cannot be performed.
3. If there is no alarm output, change the setting of the following servo amplifier parameter.
Pr.62
0
4. The A-phase, B-phase, Z-phase and alarm signals must be provided as differential line driver outputs.
5. Set the internal setting switch (SW1) to CLOSE.
6. If the current consumption of the linear scale exceeds 150mA, supply external power.
7. Connect the shield wire to the plate (ground plate) in the connector securely.
8. Use a cable that can endure bending motion for a long time.
9. Because of RS-422 communication, the cable length is maximum 30m. However, it may be necessary to shorten the length
depending on the power supply voltage drop and linear scale specifications.
10. As the connection cable, use the MR-J2HBUS05M or MR-J2HBUS1M.
11. When a connection cable is to be fabricated, the cable length should be within 1m.
