15.9.2 Regenerative option
CAUTION
The specified combinations of regenerative options, converter unit and drive unit
may only be used. Otherwise, a fire may occur.
may only be used. Otherwise, a fire may occur.
POINT
The calculation method of regenerative energy is the same as that for servo
amplifiers with 22kW or less. Refer to section 12.2 (2).

Note. 1. The composite resistance value of three options is 1.3 . The resistance value of each is 4 .
2. The composite resistance value of three options is 5 . The resistance value of each is 15 .
(2) Parameter setting
POINT
Make sure to set parameter No.PA02 of the drive unit to "
00" (Not used)
since the regenerative option cannot be connected to the drive unit.
When using the regenerative option, set the parameter of the converter unit. Match parameter No.PA01 to
the regenerative option used.
