machine position. However when the power to the PLC is turned off, this data is lost. To cope
with this the machine should return to the zero point when the power is turned ON, or during
intiial set up, to teach the zero position.
Points to note:
a)Users may specify zero return speed [S
b)Users may specify the creep speed [S
c)If any device other than an input relay (X) is specified for the Near point signal [S3] it will be
affected by the operation cycle of the PLC and the dispersionof the zero point may be large.
d)Only Y000 or Y001 can be used for the pulse output [D].
Because of the nature of the high speed output, transistor type output units should be used
with this instruction. Relay type outputs will suffer a greatly reduced life, and will cause faulse
outputs to occur.
To ensure a ‘clean’ output signal when using transistor type units, the load current should be
200mA or higher. It may be necessary to use ‘pull up’ resistors.
e)If M8140 is set to ON, the clear signal is sent to the servo motor when the return to zero
pooint id complete.
f)Related device numbers.
g)When a Mitsubishi MR-H or MR-J2 servo amplifier equipped with absolute position detection
function is used, the current position of the servo can be read by FNC 155 (ABS).
• Dog search function is not supported. Start zero return from thr front side of the Near point
• Attention should be paid to the instruction drive timing.
