5.5.1 Names and Descriptions of Main Circuit Terminals
The following table provides the names and a description of main circuit terminals.
Table 5.5 Main Circuit Names and Description
∗ 1. No B3 terminal.
∗ 2. These terminals do not exist on SERVOPACKs with a capacity of 6
kW or higher.
∗ 3. This terminal is on SERVOPACKs with a capacity of 6 kW or higher
only.
Terminal
Symbol
Name Description
L1, L2
or
L1, L2, L3 Main circuit AC input
terminal 30 W to 200 W Single-phase 100 to 115 V +10%, -15% (50/60 Hz)
30 W to 400 W Single-phase 200 to 230 V +10%, -15% (50/60 Hz)
0.5 kW to 7.5 kW Three-phase 200 to 230 V +10%, -15% (50/60 Hz)
U, V, W Servomotor
connection terminal Connects to the Servomotor.
L1C, L2C Control power input
terminal 30 W to 200 W Single-phase 100 to 115 V +10%, -15% (50/60 Hz)
30 W to 7.5 kW Single-phase 200 to 230 V +10%, -15% (50/60 Hz)
(2 places)
Ground terminal Connects to the power supply ground terminals and motor ground termi-
nal.
B1, B2
or
B1, B2, B3 External
regenerative resistor
terminal 30 W to 40 W Normally not connected.
Connect an external regenerative resistor (provided
by customer) between terminals B1 and B2 if the
regenerative capacity is insufficient.
*1
0.5 kW to 5.0 kW Normally short terminals B2 and B3 (for an internal
regenerative resistor).
Remove the wire between terminals B2 and B3 and
connect an external regenerative resistor (provided
by customer) between terminals B1 and B2 if the
capacity of the internal regenerative resistor is insuf-
ficient.
6.0 kW, 7.5 kW Connect an external regenerative resistor (provided
by customer) between terminals B1 and B2.
*1
1， 2 *2 DC reactor terminal
connection for power
supply harmonic
wave
countermeasure
Normally short 1 and 2.
If a countermeasure against power supply harmonic waves is needed, con-
nect a DC reactor between
1 and 2.
*3
Main circuit plus
terminal Normally not connected.
Main circuit minus
terminal Normally not connected.
