11.2 Regenerative options
CAUTION
The specified combinations of regenerative options and drivers may only be used.
Otherwise, a fire may occur.

(2) Selection of the regenerative option
Use the following method when regeneration occurs continuously in vertical motion applications or when it
is desired to make an in-depth selection of the regenerative option.
(3) Parameter setting
Set parameter No. PA02 according to the regenerative option to be used.
Selection of regenerative option
00: Regenerative option is not used
For servo amplifier of 100W, regenerative resistor is not used.
For servo amplifier of 200 to 400W, built-in regenerative resistor is used.

(4) Connection of the regenerative option
POINT
When using a regenerative option, remove the built-in regenerative resistor
and its wirings from the driver.
For the sizes of wires used for wiring, refer to section 11.5.
Avoid installing and removing the built-in regenerative resistor frequently, as
much as possible.
When reinstalling the removed built-in regenerative resistor, check if there is
no damage on the lead of the built-in regenerative resistor.
The regenerative option causes a temperature rise of 100
relative to the ambient temperature. Fully
examine heat dissipation, installation position and used wires, etc. before installing the option. For wiring,
use flame-resistant wire and keep them clear of the regenerative option body. Always use twisted cables of
max. 5m length for connection with thedriver.

-S3
LECSA2-S4, disconnect the wiring to P and C,
remove the built-in regenerative resistor from the driver, and then connect the regenerative option to P and
C. G3 and G4 are thermal sensor output terminals. G3-G4 is disconnected when the regenerative option
overheats abnormally.
Selection of regenerative option
00:Regenerative option is not used
・
For driver of 100W, regenerative resistor is not used.
・
For driver of 200W to 400W, regenerative resistor is not used.
