1. FUNCTIONS AND CONFIGURATION
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. The communication cycle depends on the controller specifications and the number of axes connected.
5. 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. For wiring of the external
dynamic brake, refer to section 11.17 of "MR-J4-_B_(-RJ) Servo Amplifier Instruction Manual".
6. The external dynamic brake cannot be used for compliance with SEMI-F47 standard. Do not assign DB (Dynamic brake
interlock) in [Pr. PD07] and [Pr. PD08]. Doing so will cause the servo amplifier to become servo-off when an instantaneous
power failure occurs.
7. Follow the restrictions in section 2.7 of "MR-J4-_B_(-RJ) Servo Amplifier Instruction Manual" when using the servo amplifiers
at altitude exceeding 1000 m and up to 2000 m above sea level.
