4-2-1 Peripheral Equipment Connection Examples
*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. There is no polarity on the brakes.
*3. There is no built-in regeneration resistor. Connect a required regeneration resistor between B1 and B2.
*4. 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.
*5. To ensure safety, install a leakage breaker for the main circuit power supply input in the control panel. Refer to 4-3-2
Selecting Connection Component on page 4-62.
*6. Recommended products are listed in 4-3 Wiring Conforming to EMC Directives on page 4-47. You cannot use the DC
reactor.
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.
