*1. The default setting is 0 for a Drive with 100 V and 400 W, with 200 V and 750 W or greater, or with 400 V.
The setting is different whether the Regeneration Resistor built in the Drive is directly used, or it is
removed and replaced by an external regeneration resistor. In the latter case, the resistor is
connected to the external regeneration resistor connection terminal.
Explanation of Set Values
Precautions for Correct Use
 Do not touch the External Regeneration Resistor. A burn injury may result.
Always provide a temperature fuse or other protective measure when using an external
regeneration resistor. Regardless of whether the regeneration overload error is enabled or
disabled, the Regeneration Resistor can generate heat and may cause burning.
To use the Built-in Regeneration Resistor, always set this object to 0.
Select the method to calculate the regeneration resistance load ratio, when the External Resistor
is selected in the Regeneration Resistor Selection (3016 hex = 1 or 2).

Description
0
Regeneration Resistor used: Built-in Resistor
The regeneration processing circuit operates and the Regeneration Overload Error (Error No.
18) are enabled according to the Built-in Resistor (with approx. 1% duty).
1
Regeneration Resistor used: External Resistor
The regeneration processing circuit operates, and Regeneration Overload Error (Error No.
18) cause a trip when the operating rate of the Regeneration Resistor exceeds 10%.
2
Regeneration Resistor used: External Resistor
The regeneration processing circuit operates, but Regeneration Overload Error (Error No.
18) do not occur.
3
Regeneration Resistor used: None
The regeneration processing circuit and Regeneration Overload Error (Error No. 18) do not
operate, and all regenerative energy is processed by the built-in capacitor.
