The MR-J3-A are general purpose
servo amplifiers with analog inputs
and pulse train interface as a stan
-
dard. The range covers 100 W units
(MR-J3-10A) up to 7 kW (MR-J3-700A).
The MR-J3-B (SSCNET III bus type)
servo amplifiers are designed for use
with the Mitsubishi motion control-
lers of the MELSEC System Q series.
The motion controllers and servo
amplifiers can be linked via the high
speed SSCNET III network.
Connecting the amplifiers to
SSCNET III guarantees reliable opera
-
tion and eliminates the need for com
-
plex wiring.
The range also covers 100 W units
(MR-J3-10B) up to 7 kW (MR-J3-700B).
MR-J3-A/B servo amplifers of
increased capacity (up to 55 kW)
are availible on request only.
