1. Details of parameter
[Class 0] Basic setting
Title
Pr0.16 *
Range
With this parameter, you can select either to use the built-in regenerative resistor of the
driver, or to separate this built-in regenerative resistor and externally install the regenerative
resistor (between B1 and B2 of Connector XB in case of A to D-frame, between B1 and B2
of terminal block in case of E, F-frame).

(A, B-frame)
Remarks
Install an external protection such as thermal fuse when you use the external regenerative
resistor.
Otherwise, the regenerative resistor might be heated up abnormally and result in burnout,
regardless of validation or invalidation of regenerative over-load protection.
Caution
When you use the built-in regenerative resistor, never to set up other value than 0. Don't
touch the external regenerative resistor.
External regenerative resistor gets very hot, and might cause burning.
Title
Pr0.17 *
Range
When selecting the external regenerative resistor (Pr0.16 = 1, 2), select the computing
method of load factor of regenerative resistor.

resistor
to be used
Regenerative processing circuit will be activated and regenerative
Built-in resistor resistor overload protection will be triggered according to the
built-in resistor (approx. 1% duty).
The driver trips due to regenerative overload protection (Err18.0),
External resistor when regenerative processing circuit is activated and its active
ratio exceeds 10%.
Regenerative processing circuit is activated, but no regenerative
External resistor
over-load protection is triggered.
Both regenerative processing circuit and regenerative protection
No resistor are not activated, and built-in capacitor handles all regenerative
power.
Load factor of external regenerative
resistor selection
0 to 4
Regenerative load factor is 100% when duty factor of external regenerative resistor is
10%.
