Pn016 Regeneration Resistor Selection
Setting 0 to 3
range
*1 The default setting is 0 for a Servo Drive with 200 V and 750 W or more.
Explanation of Set Values
Set value
0 Regeneration Resistor used: Built-in Resistor
The regeneration processing circuit operates and Regeneration Overload (Alarm No. 18) operates
according to the Built-in Resistor (with approx. 1% duty).
1 Regeneration Resistor used: External Resistor
The regeneration processing circuit operates and Regeneration Overload (Alarm No.18) causes 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 (Alarm No. 18) does not
operate.
3 Regeneration Resistor used: None
The regeneration processing circuit and Regeneration Overload (Alarm No. 18) do not operate,
and all regenerative energy is processed by the built-in capacitor.
• Do not touch the External Regeneration Resistor. The External Regeneration Resistor will become
hot and 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 is enabled or disabled, the
Regeneration Resistor can generate heat and may cause burning.
• Use this parameter to select whether to use the Built-in Regeneration Resistor as is or use an
External Regeneration Resistor (connected to the External Regeneration Resistor connector) with
the Built-in Regeneration Resistor disconnected.
• To use the Built-in Regeneration Resistor, always set this parameter to 0.
