9.5.6 Detailed Connecting Methods of External Regenerative Resistors
The following figures describe detailed connecting methods of external regenerative resistors.
When changing connections of the regenerative resistor, make sure to change the relevant parameters, too.

Terminal differences depending on amplifier capacity
For amplifier capacity of 15 A or 30 A
There are two connecting terminals for the
regenerative resistor, P and Y (or COM).
(There is no X terminal.)
For amplifier capacity of 50 A
There are three connecting terminals for the
regenerative resistor, P, Y and X.
(There is no COM terminal.)
When connecting an external regenerative resistor,
be sure to remove the short-circuit bar across the P
and X terminals before connecting it.
