Note 1. The value is at the HG series servo motor driving.
2. The motor-less operation for the linear servo motor and direct drive motor driving will be available in the future.
3. It is not available with MR-J4W3-_B servo amplifiers.
4. It is not available with the MR-J3W-_B, MR-J4W2-_B, and MR-J4W3-_B servo amplifiers.
5. It is not available with the MR-J4W2-_B and MR-J4W3-_B servo amplifiers.
6. The minute position detection method is available instead.
7.
A
larm history will be saved up to five times.
8. The functions of the product with modified parts (GA) in the MR-J3-_B servo amplifiers are all covered by the J3 compatibility
mode of the MR-J4-_B servo amplifiers.
9. MR-J4W3-_B servo amplifiers do not support the fully closed loop control system.
10. For MR-J4 series, the robust filter and vibration tough drive are available instead.
11. The operation mode will be identified automatically at the first controller communication. You can change the operation mode
with the application "MR-J4(W)-B mode selection".
12. When MR-J4 is used as a replacement of MR-J3-_S, "Servo forced stop selection" in [Pr. PA04] will be "Disabled (_ 1 _ _)" in
the initial setting. Change the setting as necessary.
13. This is for MR-J4-_B servo amplifier. MR-J4-_B-RJ servo amplifier is compatible with two-wire type, four-wire type, and A/B/Z-
phase differential output method.
14. It is available with only MR-J4-_B-RJ servo amplifiers. It is not available with MR-J4-_B servo amplifiers.
15. This is available when the J3 extension function is enabled. Refer to section 17.1.9 for details.
16. For servo system controllers which are available with this, contact your local sales office.
