3.5.1 Terminal Symbols and Terminal Names
Use the main circuit connector or terminal block on the SERVOPACK to wire the main circuit
power supply and control circuit power supply to the SERVOPACK.
The SERVOPACKs have the following three types of main circuit power supply input specifica-
tions.
•
Three-Phase, 200-VAC Power Supply Input
•
Single-Phase, 200-VAC Power Supply Input
CAUTION

Wire all connections correctly according to the following table and specified reference infor-
mation. There is a risk of SERVOPACK failure or fire if incorrect wiring is performed.

3.5.5 Wiring Regenerative Resistors on page 3-32
If the internal regenerative resistor is insufficient, remove the
lead or short bar between B2 and B3 and connect an Exter-
nal Regenerative Resistor between B1/ and B2. The Exter-
nal Regenerative Resistor is not included. Obtain it separately.
1 and 2
DC Reactor terminals for
power supply harmonic
suppression
3.5.6 Wiring Reactors for Harmonic Suppression on page 3-33
These terminals are used to connect a DC Reactor for power
supply harmonic suppression or power factor improvement.
– None. (Do not connect anything to this terminal.)
