1. FUNCTIONS AND CONFIGURATION
1 - 16
Note 1. 0.3 A is the value applicable when all I/O signals are used. The current capacity can be decreased by reducing the number of
I/O points.
2. Test pulse is a signal which instantaneously turns off a signal to the servo amplifier at a constant period for external circuit to
self-diagnose.
3. Except for the terminal block.
4. MR-J4-B4 servo amplifier is compatible only with two-wire type. MR-J4-B4-RJ servo amplifier is compatible with two-wire type,
four-wire type, and A/B/Z-phase differential output method. Refer to table 1.1 for details.
5. The communication cycle depends on the controller specifications and the number of axes connected.
6. Use an external dynamic brake for this servo amplifier. Failure to do so will cause an accident because the servo motor does
not stop immediately but coasts at emergency stop. Ensure the safety in the entire equipment.
7. For the compatible version for the scale measurement function, refer to table 1.1. Check the software version of the servo
amplifier using MR Configurator2.
8. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake
interlock) in [Pr. PD07] to [Pr. PD09]. Failure to do so will cause the servo amplifier to become servo-off when an
instantaneous power failure occurs.
