Parameters Details
Explanation of Set Values
Set the operating method for the 17-bit absolute encoder.
Default settings:
(1) Pn016 = 0 - For 200V drives of 750 W or upper and 400V drives
(2) Pn016 = 3 - For 200V drives of less than 750 W
Explanation of Set Values
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 is enabled or disabled,
the Regeneration Resistor can generate heat and may cause burning.
Set this parameter depending on whether the Built-in Regeneration Resistor is used, or the Built-
in Regeneration Resistor is disconnected and an External Regeneration Resistor is connected.
(The External Regeneration Resistor connection terminal is connected.)
To use the Built-in Regeneration Resistor, always set this parameter to 0.

Regeneration Resistor used: Built-in Resistor
The regeneration processing circuit will operate and the regeneration overload (alarm display
No. 18) will be enabled according to the Built-in Resistor (with approx. 1% duty).
1
Regeneration Resistor used: External Resistor
The regeneration processing circuit will operate, and regeneration overload (alarm display
No. 18) will cause a trip when the operating rate of the Regeneration Resistor exceeds 10%.
2
Regeneration Resistor used: External Resistor
The regeneration processing circuit will operate, but regeneration overload (alarm display
No. 18) will not occur.
3
Regeneration Resistor used: None
The regeneration processing circuit and regeneration overload (alarm display No. 18) will not
operate, and all regenerative energy will be processed by the built-in capacitor.
