3.3.1. Names and Descriptions of Main Circuit Terminal
The following table gives the names and a description of main circuit
terminals.
Table 3.1: Main Circuit Names and Description
Terminal
Symbol
Name Description
L1, L2 30W to 1kW Single-phase 200 to 230V (+10%, -15%), 50/60Hz
1kW to 3kW Three-phase 200 to 230V (+10%, -15%), 50/60Hz
L1, L2, L3*
Main circuit AC input
terminal
2kW to 3.0kW 400V Three-phase 380 to 480V (+10%, -15%), 50/60Hz
U, V, W
Servomotor connection
terminal
Connects to the Servomotor.
Single-phase 200 to 230V (+10%, -15%), 50/60Hz
L1C, L2C
Three-phase 200 to 230V (+10%, -15%), 50/60Hz
24V, 0V
Control power input
terminal
30W to 3.0kW
24VDC (±15%) 400V units only
(2 places)
Ground terminal Connects to the power supply ground terminals and motor ground terminal.
30W to 400W
Normally not connected.
Connect an external regenerative resistor
(provided by customer) between B1 and B2 if the
regenerative capacity is insufficient.
Note: No B3 terminal.
B1, B2 or
B1, B2, B3
External regenerative
resistor terminal
800W to 3.0kW
Normally short B2 and B3 (for an internal
regenerative resistor).
Remove the wire between B2 and B3 and connect
an external regenerative resistor (provided by
customer) between B1 and B2 if the capacity of
the internal regenerative resistor is insufficient.
1, 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,
connect a DC reactor between 1 and 2.
The amplifier is delivered from the factory with these terminals shorted.
See
5.8.6 Reactor for Harmonic Suppression
for details.
Main circuit Positive
terminal
Normally not connected.
Main circuit Negative
terminal
Normally not connected.
*XtraDrive XD-08 has single-phase, 200V power supply specifications. Connect the
following power supply between L1 and L3.
Single-phase 220 to 230 VAC
+10%, -15%
(50/60Hz)
When a power supply of 187V(-15% of 220V) or less is used, an alarm 41, indicating
voltage shortage, may occur when accelerating to max speed with max torque of motor.
