*3 When using the sensing module in axis mode, there are no restrictions on the number of stations for the sensing module.
*4 When AlphaStep/5-phase is present, operation is carried out at 0.444ms operation cycle.
*5 When FR-A700 series, VC
series, or VPH series are present, operation is carried out at 0.444ms operation cycle.
*6 When the setting exceeds the number of control axes per controller, a minor error (error code: 1C83H) occurs.
Set the operation cycle as follows according to the number of control axes per controller.
• When using MR-J4W-
B, if there is at least one axis which has not been set in servo network setting, all axes of the
applicable servo amplifier cannot be connected, and all servo amplifiers after the applicable servo amplifier 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.
• When using a multi-axis servo amplifier (MR-J4W-
B), there is a restriction on the number of connectable units (servo
amplifier (MR-J4(W)-
B), SSCNET
/H head module, other drivers etc.) between the Motion CPU and the multi-axis servo
amplifier. The number of connectable units are shown below. When more than the number of connectable units are
connected, a warning (error code: 0C82H) occurs. While communication with MR-J4W-
B is still possible when the
warning occurs, communication becomes unstable, therefore the unit configuration should be reviewed. Furthermore, when
an optical hub unit is used, the number of connectable units is reduced. Refer to the following for details of when an optical
hub unit is connected.
