2-2-2 Names and application of main circuit terminal block and control circuit terminal
block signals
The following table shows the details for each terminal block signal.
Name Signal name Description
L1·L2·L3
Main circuit
power supply
Main circuit power supply input terminal
Connect a 3-phase 200 to 230VAC, 50/60Hz power supply.
L11·L12
Control circuit
power supply
Control circuit power supply input terminal
Connect a single-phase 200 to 230VAC, 50/60Hz power supply.
Connect the same power supply phase for L11 and L1, and L21 and L2.
P·C·D
Regenerative
option
Regenerative option connection terminal. P to D is wired at shipment.
When using the regenerative option, disconnect the wire between P and D and wire
the regenerative option between P and C.
(N)
Main circuit
reference
potential
This is not used normally.
(This is the reference potential for the main circuit DC voltage.)
U·V·W
Servomotor
output
Servomotor power supply output terminal
The servomotor power supply terminal (U, V, W) is connected.
Protective
grounding (PE)
Grounding terminal
The servomotor grounding terminal is connected and grounded.
DANGER
Never connect anything to the main circuit reference voltage (N).
Failure to observe this could lead to electric shock or servo amplifier damage.
CAUTION
When using a standard built-in regenerative resistor, connect it between the P
and D terminals. (Shipment state.)
When using an external option regenerative resistor, disconnect the wiring
between the P and D terminals, and connect between P and C. Standard
built-in regenerative resistors cannot be used in combination with an external
option regenerative resistor.
