5.3 Wiring for power supply (CN1)
5.3.1 Terminal symbols and terminal names
Wirings for main circuit power supply and control circuit power supply are described as below.
Wiring must be correctly performed by referring to this section. Incorrect wiring may cause product malfunction
and fire.
The power input for the servo drive main circuit can be three-phase AC 220 V or single-phase AC 220 V.
(1) Three-phase AC 220 V power input
Table5.3.1.1
Function Description
L1, L2, L3
AC main power
input terminals
Three-phase AC 200 V～240 V, -15%～+10%, 50/60 Hz
L1C, L2C
Control power input
terminals
Single-phase AC 200 V～240 V, -15%～+10%, 50/60 Hz
B1/⊕, B2,
B3
Terminals for
regenerative
resistor
When the capacity of internal regenerative resistor is insufficient,
use B1/⊕ and B3 terminals to connect to external regenerative
resistor. External regenerative resistor is an optional purchase. B2
terminal is for internal regenerative resistor.
⊝1, ⊝2
Terminals for DC
reactor
The terminals are used to connect to DC reactor to suppress high
order harmonic and improve power factor. If DC reactor is not used,
connect the terminals with the wire provided with the servo drive.
⊝ Do not connect.
(2) Single-phase AC 220 V power input
Table5.3.1.2
Function Description
L1, L2
AC main power
input terminals
Single-phase AC 200 V～240 V, -15%～+10%, 50/60 Hz
L1C, L2C
Control power input
terminals
Single-phase AC 200 V～240 V, -15%～+10%, 50/60 Hz
