Caution
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 P and B of Connector XB in case of A to D-frame, between P and B of
Connector XC in case of E-frame, between P and B of terminal block in case of F-frame).
A, B-frame driver is not provided with built-in resister.
Setup value
Regenerative
resistor
to be used
Function
[0]
(C to F-frame)
Built-in resistor
Regenerative processing circuit will be activated and
regenerative resistor overload protection will be triggered
according to the built-in resistor (approx. 1 % duty).
1
External
resistor
The driver trips due to regenerative overload protection
(Err18.0), when regenerative processing circuit is activated and
its active ratio exceeds 10 %.
2
External
resistor
Regenerative processing circuit is activated, but no regenerative
over-load protection is triggered.
[3]
(A, B-frame)
No resistor
Both regenerative processing circuit and regenerative protection
are not activated, and built-in capacitor handles all regenerative
power.
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.
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.
