The RGH26 readheads are a new
addition to Renishaw’s proven RG2 range of
linear encoder systems. The RG2 range
consists of non-contact optical encoders
designed for precision position feedback
solutions. The system uses a reflective tape
scale scanned by a readhead chosen from a
range of options. It offers industry standard
digital square wave, analogue sinusoidal, and
now Mitsubishi-comp atible serial communication
signal formats. Renishaw’s patented filtering
optical scheme is used in all RG2 linear
encoders and gives outstanding performance
combined with a high tolerance to dust,
scratches and light oil contamination.
The RGH26 range has been specifically
designed for use with Mitsubishi’s
MELSERVO®-J2-Super series range of servo
amplifiers. The RGH26 range offers exceptional
high speeds of up to 6m/s with high
resolutions of up to 0.5µm.
Unlike other serial communication systems for
linear encoders, the RGH26 does not require a
separate bulky interface. Renishaw’s innovative
electronics design means that all of the
interpolation and serial conversion is contained
within the same compact body as the popular
RGH22. The incremental count takes place within
the readh ead, r es ult in g i n remark ab le s ys tem noise
immunity.
Dual limit sensors have been incorporated as
standard, offering two dedicated signal outputs, for
left and right end-of-axis travel indication. A
repeatable reference mark output is also included,
along de dicated real-t ime channels, as well as part
of the serial word.
The class-leading compact size, exceptional high
speed, high accuracy, and zero-friction
configuration make the RGH26 range the encoder
of choic e for linear fe edback app lications wher ever
a MELSERVO®-J2-Super is used.
