The MR-J3-A are general purpose servo
amplifiers with analog inputs and pulse
train inter face as a standard. The range
covers 100 W units (MR-J3-10A) through
to 7 kW (MR-J3-700A).
The MR-J3-B (SSCNET III bus type) servo
amplifiers are designed for use with the
Mitsubishi motion controllers of the
MELSEC System Q series. The motion
controllers and s ervo amp lifiers can be
linked via the high speed SSCNE T III net-
work.
Connecting the amplifiers to SSCNE T
guarantees reliable operation and
eliminates the need for complex
wiring. The range also covers 100 W
units (MR-J3-10B) through to 7 kW
(MR-J3-700B).
A ser vo amplifier with built-in position
-
ing (MR-J3-T) is available s oon.
Positioning via position tables (target
position, motor speed, accelera
-
tion/deceleration ramp). The MR-J3-T
can store 256 position tables, accessed
via ex ternal inputs or CC-Link.
