1. FUNCTIONS AND CONFIGURATION
1 - 12
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 drive unit 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 drive unit. 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 9.3 of "MR-J4-DU_(-RJ)/MR-CR55K_ 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 drive unit to become servo-off when an instantaneous power
failure occurs.
7. Follow the restrictions in section 2.5 of "MR-J4-DU_(-RJ)/MR-CR55K_ Instruction Manual" when using the drive units at
altitude exceeding 1000 m and up to 2000 m above sea level.
(3) Converter unit
For standard specifications of MR-CR55K and MR-CR55K4, refer to section 1.2 of "MR-J4-DU_(-
RJ)/MR-CR55K_ Instruction Manual".
