*1. Recommended products are listed in
4-3 Wiring Conforming to EMC Directives
on page 4-47. This connection example
is for when the book-type noise filter is used. When you use the footprint-type noise filter, built the system to directly con-
nect the noise filter and the Servo Drive. 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. Short-circuit B2 and B3 for models with a built-in regeneration resistor (1SN04L-ECT and 1SN08H-ECT). 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. There is no internal regeneration resistor for 1SN01L-ECT to 1SN02L-ECT and 1SN01H- ECT to 1SN04H-ECT. When
the amount of regeneration is large, connect the necessary regeneration resistor between B1 and B2.
*5. To ensure safety, install a leakage breaker for the main circuit power supply input in the control panel. Refer to
Selecting Connection Component
*6. 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.
*7. External connection components are not required because a brake relay and a surge absorbing element are built into
the Servo Drive.
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.
