The type of ground terminal on the Programmable Multi-Axis Controller is a functional ground terminal.
A functional ground terminal takes protective measures for device and system functions, including pre-
vention of noises from external sources, and prevention of noises from devices or equipment that may
have harmful effects on other devices or equipment.
• Ground to 100
Ω
or less, and as possible use a separate ground from those of other devices.
• If using an independent ground is not possible, then use a common ground. Connect to the ground
pole of the other device.
• Never use a common ground particularly with a motor, inverter, or other type of high-power equip-
ment. Use an independent ground so that they do not affect each other.
• To reduce the risk of receiving an electric shock, do not connect devices to ground poles to which
multiple devices are connected.
• Use a ground pole as close to the Programmable Multi-Axis Controller as possible and keep the
ground line as short as possible.
Use a flat-head screwdriver to connect and remove wires.
The recommended screwdriver is as follows.
The following shows the procedure for wiring the power supply connector.
1
Peel off the sheath from the power supply cable.
The stripping length is 7 mm if a bar terminal is not used.
If a bar terminal is used, the stripping length must be determined according to the specification
of the bar terminal.
2
Loosen the screws securing wires on the top of the power supply connector to release the wire
insertion ports.
