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 Descriptions
Terminal
Symbol
Name Description
L1, L2 30 W to 1.0 kW Single-phase 200 to 230 V (+10%, -15%), 50/60 Hz
1.0 kW to 3.0 kW Three-phase 200 to 230 V (+10%, -15%), 50/60 Hz
L1, L2, L3*
Main circuit AC input
terminal
2.0 kW to 5.0 kW
400 V
Three-phase 380 to 480 V (+10%, -15%), 50/60 Hz
U, V, W
Servomotor
connection terminal
Connects to the Servomotor.
Single-phase 200 to 230 V (+10%, -15%), 50/60 Hz
L1C, L2C
Three-phase 200 to 230 V (+10%, -15%), 50/60 Hz
24V, 0V
Control power input
terminal
30 W to 5.0 kW
24 VDC (±15%) 400 V units only
(2 places)
Ground terminal Connects to the power supply ground terminals and motor ground terminal.
30 W to 400 W
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
800 W to 5.0 kW
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
Appendix B.6 Reactor for Harmonic Suppression for details.
Main circuit Positive
terminal
Normally not connected.
Main circuit Negative
terminal
Normally not connected.
*Models FSP-08A* and FSP-15A* are single-phase, 220 V power supply specifications.
Connect the following power supply between L1 and L3.
Single-phase 220 to 230 VAC +10%, -15% (50/60 Hz)
When a power supply of 187 V (-15% of 220 V) or less is used, an alarm A.41, indicating
voltage shortage, may occur when accelerating to max speed with max torque of motor.
