Series
Notes: 1. 0.75 kW or smaller servo amplifiers are available for 1-phase 200 V AC.
2. 0.6 kW, and 1 kW or larger servo amplifiers are available.
3. SSCNET III/H interface is not available in the J2S compatibility mode.
4. Available in 7 kW or less servo amplifier without a built-in dynamic brake.When using the servo amplifier without a dynamic brake, the servo motor does not stop
immediately at an alarm occurrence or power failure. Take measures to ensure safety on the entire system.
When the following servo motors are used, the electronic dynamic brake may operate at an alarm occurrence.
HG-KR053, HG-KR13, HG-KR23, HG-KR43, HG-MR053, HG-MR13, HG-MR23, HG-MR43, HG-SR51, and HG-SR52
Disable the electronic dynamic brake by setting [Pr. 56] to "2_ _ _."
5. MR-J4-T20 conversion unit for SSCNET of MR-J2S-B is required to make the servo amplifier be compatible with SSCNET interface.
When MR-J4-B-RJ020 and MR-J4-T20 are combined, MR-J4-B-RJ020 is compatible with the following servo system controllers:
A171SHCPU(N), A172SHCPU(N), A173UHCPU, A1SD75M, QD75M, Q172CPU(N), and Q173CPU(N)
6. Available in 11 kW to 22 kW servo amplifier. A regenerative resistor (standard accessory) is not enclosed.
7. 0.4 kW or smaller servo amplifiers are available.
