Notes and Remarks
1. MR-J2-B allows the use of the following
motors with high-resolution encoders.
•
HC-MF***W1 (32768PLS)
•
HA-FF***W1 (32768PLS)
•
HC-SF**2W2 (131072PLS)
2. [Allowable travel value during power-off]
When ABS motor is used, set the
allowable travel value during servo
amplifier power-off by rpm (rotations per
minute).
This setting value is used for checking
when the servo amplifier is switched ON.

• Max. 8 axes for
A172SHCPUN
• Max. 4 axes for
A171SHCPUN
•
Connect the servo
amplifier to the
'SSCNET1'
interface.
•
The setting range
changes for high-
resolution encoder
support.
1. External signals
(1) Set the axis numbers of external
signals FLS, RLS, STOP, and
DOG/CHANGE for A172SENC CTRL
connector signals PX0 to PX1F.
Axes need not be set unless they are
used by external signals.

The conventional
A171SENC can
also be used for
A171SHCPUN and
A172SHCPUN.
However, it must
be set as
A172SENC during
system setting.

1. Set the number of points and the starting
I/O number for PC CPU I/O modules to be
mounted on the motion extension base
unit.
The number to be set must not precede
the I/O numbers for use by the PLC
extension base unit.
