Figure 1-2 Wiring example of three-phase 220 V/380 V system
Circuit breaker for
wiring
Used to protect power
lines by cutting off the
circuit when an
overcurrent
occurs.
Noise filter
Avoid the external
noise from the power
lines by installing a
noise filter.
Electromagnetic
contactor
Turn on/off the
servo motor.
Please install a
surge protection
device (SPD)
before use.
Regenerative
resistor
Terminal P-C
connects to the
external regenerative
resistor if there is
insufficient capacity
for the bus.

The servo drive is directly connected to an industrial power supply, with no isolation such as transformers.
Inthiscase,afuseorcircuitbreakermustbeconnectedontheinputpowersupplytopreventcrosselectric
accidentsintheservosystem.Theservodriveisnotconguredwiththebuilt-inprotectivegroundingcircuit.
Connect a residual current device (RCD) against both overload and short-circuit or a specialized RCD com-
bined with protective grounding.
Do not use magnetic contactors for running or stopping the servo motor. As a high-inductance device, the
motor generates instantaneous high voltage, which may damage the contactor.
Pay attention to the power capacity when connecting an external control power supply or 24 V DC, especially
whenthepowersupplyisforpoweringupmultipledrivesorbrakes.Insufcientpowersupplywillleadtoa
lackofthesupplycurrent,thuscausingafailureofthedrivesorbrakes.Thebrakeshallbepoweredupbya
24VDCpowersupply.Thepowermustmatchthemotormodelandmeetsthebrakerequirements.
Observethefollowingprecautionsduringwiring:
1. ProvideableederresistorbetweenterminalPandCwhentheservosystemisunderfeedbackbraking
mode.
2. CN3 is an Ethernet interface, and CN4 and CN5 are for connecting EthnerCAT. CN4 is used to connect
the next slave device, while CN5 is used to connect the master station or previous slave device.
