Part 1 Installation
[1] FG terminal
This terminal is used to ground FG on the enclosure. The enclosure is
connected to PE in the AC input part inside the controller.
FG Terminal Specifications
Item Description
M4 3-point SEMS screw, 5 mm
Name FG
Cable size 2.0 ~ 5.5 mm
2
min.
Grounding method Class D grounding
[2] External regenerative
unit connector
(Linear movement axis
only)
When a linear movement axis decelerates or moves downward, regenerative
energy is produced. The capacitor and resistor in the controller alone may not
be able to absorb this regenerative energy (in which case an “Error No. 60C,
Power-system overhear error” will generate). In this case, connect a
regenerative unit or units.
Whether or not your system needs one or more regenerative units depends on
the specific application such as the configuration of linear movement axes.
Refer to Appendix, “Number of Regenerative Units to be Connected.”
If all axes are SCARA axes, no regenerative unit is required.
