1 Introduction
1.1 Features and configuration
Apart from possessing the functions of the servo amplifiers MR-J2-Series, the servo amplifiers
MR-J2-Super have additional features and functions.
The servo amplifiers MR-J2S-B and MR-J2S-B4 are designed for operation with a Mitsubishi-
Motion-Controller via a serial bus (SSCNET). For this the servo amplifier reads in the position
data directly so that it can then execute the positioning process.
Through the specification of speed and direction of rotation via the command unit, precise
positioning is possible. To protect the power transistor against over-current resulting from great
accelerations or delays or overload the servo amplifier is equipped with a speed limitation
feature. The value for speed limitation can be varied and may be specified via an external
analogue input or a parameter.
The RS232C or RS422 interface permits serial communications between the servo amplifier
and a PC. Using the Windows-supported setup software, functions such as parameter setting,
test runs, status display, amplifier setting, etc. can be carried out. By means of real-time auto-
tuning it is possible to undertake an automatic adjustment of the amplifier settings to the
machine.
The MR-J2-Super series servo motor is equipped with an absolute position encoder which has
the resolution of 131072 pulses/rev to ensure more accurate control as compared to the MR-J2
series.
Simply adding a battery to the servo amplifier makes up an absolute position detection system.
This makes home position return unnecessary at power-on or alarm occurrence by setting a
home position once.
