*1. Recommended products are listed in
4-3 Wiring Conforming to EMC Directives
on page 4-47. When a noise filter is
used, install the surge absorber on the power supply input (LINE) side.
When wiring multiple Servo Drives from the same power supply, use one noise filter for each Servo Drive regardless of
whether the Servo Drives are operated at the same time. The noise generated from the Servo Drive may be transmitted
through the power supply cable and cause other Servo Drives to perform unexpected operations such as regeneration
operation or Overvoltage Error.
*2. External connection components are not required because a brake relay and a surge absorbing element are built into
the Servo Drive.
*3. Short-circuit B2 and B3 for models with a built-in regeneration resistor. When the amount of regeneration is large,
remove the short-circuit wire between B2 and B3 and connect a regeneration resistor between B1 and B2.
*4. When the DC reactor is not used, short-circuit N1 and N2. When the DC reactor is used, remove the short-circuit wire
between N1 and N2, and connect the DC reactor between N1 and N2.
*5. Short-circuit DB2 and DB3 for models with a built-in dynamic brake resistor. When the amount of braking energy is large,
remove the short-circuit wire between DB2 and DB3 and connect a dynamic brake resistor between DB1 and DB2.
*6. To ensure safety, install a leakage breaker for the main circuit power supply input in the control panel. Refer to
Selecting Connection Component
*7. There is no polarity on the brakes.
*8. Ground the 200-VAC input model Servo Drive to 100
Ω
or less, and the 400-VAC input model to 10
Ω
or less.
Design the configuration to cut off the main circuit power supply when the ERR signal (nor-
mally close contact) of the control output function is output (open).
Not doing so may cause a fire.
