2 SYSTEM CONFIGURATION
(15) The following are restrictions for the communication type depending on the
communication type and operation cycle settings being used.
Operation cycle
Communication type
SSCNET /H SSCNET
0.22ms
• MR-J4W3-
B (software version A2 or earlier) cannot be
used.
(Note-1)
• One SSCNET
/H head module per line can be set.
• AlphaStep/5-phase cannot be used.
(Note-2)
• Up to 2 axes per IAI electric actuator controller can be
set.
(Note-4)
• The maximum number of control axes per line is four
axes.
• Set the axis select rotary switch of the servo amplifier to
"0 to 3". If the axis select rotary switch of servo amplifier
is set to "4 to F", the servo amplifiers are not recognized.
• MR-J4W3-
B (software version A2 or earlier) cannot be
used.
(Note-1)
• MR-J3W- B cannot be used.
• FR-A700 series, VC
series, and VPH series cannot be
used.
(Note-3)
0.44ms
• Two SSCNET
/H head modules per line can be set.
• Up to 4 axes per IAI electric actuator controller can be
set.
(Note-4)
• The maximum number of control axes per line is eight
axes.
• Set the axis select rotary switch of the servo amplifier to
"0 to 7". If the axis select rotary switch of servo amplifier
is set to "8 to F", the servo amplifiers are not recognized.
0.88ms or more — —
—: No restriction
(Note-1): MR-J4W3-
B (Software version A3 or later) supports operation cycle 0.22ms. However, when
using operation cycle 0.22ms, some functions are restricted. Refer to the servo amplifier instruction
manual for details.
(Note-2): When AlphaStep/5-phase is set in system settings, operation is carried out with operation cycle at
0.44ms.
(Note-3): When FR-A700 series, VC
series, or VPH series is set in system settings, operation is carried out
with operation cycle at 0.44ms.
(Note-4): When the setting exceeds the number of control axes per controller, a major error (error code:
1350) occurs. Set the operation cycle as follows according to the number of control axes per
controller.
Number of control axes per controller Operation cycle
1 to 2 axes 0.22ms or more
3 to 4 axes 0.44ms or more
5 axes or more 0.88ms or more
(16) If there is an axis which is not set at least 1 axis by system setting in applicable
servo amplifier at MR-J4W-
B use, all axes connected to applicable servo
amplifier and subsequent servo amplifiers cannot be connected. Set "Not used"
to the applicable axis with a dip switch for the axis which is not used by
MR-J4W-
B.
