[ 6 ] Position for installation of phase compensation capacitor for slow inching specification
If the phase compensation capacitor is installed on the motor side of the loom, the inverter for slow
inching mechanism may be damaged.
Always install it on the power supply side of the inverter.
[ 7 ] When wiring the loom power cable to the loom, it is recommended to lay them at least
200 mm away from each other to prevent noise generation.
If the inverter power line is connected to the loom using a cable consisting of three power wires and
the grounding wire, do not connect the grounding wire of the inverter cable to that of the loom.
(Do not use a shielded cable as the inverter power cable. If shielding is required, use a metal con-
duit.)
For grounding the loom, use the commercial power cable consisting of three power wires and one
grounding wire and connect the grounding cable of the commercial power cable or connect the
grounding wire provided separately from the power cable.
(Each of the loom and inverter, however, must be grounded according to [ 3 ] Class D grounding.)
[ 8 ] Line filter installation to counteract radio noise
Listening to radio may become hard because of the influence of noise radiated from a loom that
uses an inverter or an AC servo motor. Insertion of a line filter in the power supply line from the plant
power distribution board to the inverter and loom is an effective countermeasure. Please consult
with an electrician for handling of the line filter.
