Details
L1
•
L2
•
L3 Main circuit power
Main circuit power input terminal
Connect to a 3-phase 200 to 230VAC, 50/60Hz power
supply.
L11
•
L12 Control circuit power
Control circuit power input terminal
Connect to a single-phase 200 to 230VAC, 50/60Hz power
supply.
Connect so the power phase of L11 is the same as L1, and
that of L21 is the same as L2.
Failure to observe this will may result in failure.
P
•
C
Regenerative resistor
connection
Regenerative resistor connection terminal
Wire the regenerative resistor between P and C.
(N)
Main circuit standard
potential
This is normally not used.
(This is the standard potential of the main circuit DC voltage.)
Caution
Do not connect anything to this terminal unless
specifically instructed by Mitsubishi. Failure to
observe this could result in electric shocks or
spindle amplifier damage.
U
•
V
•
W
Spindle motor output
Spindle motor power output terminal
Connect to the spindle motor power terminal (U, V, W).
PE Ground
Grounding terminal
Ground by connecting to the spindle motor grounding
terminal.
