Explanation
Set the operation to be performed after stopping or dur-
ing deceleration when any protective function of the
Servo Drive operates and an error occurs.
During deceleration: Dynamic brake

During deceleration: Free run

Set the operation to be performed after the Servomotor
turns OFF (i.e., RUN ON to OFF).
The relation between set values, operation, and devia-
tion counter processing for this parameter is the same
as for the Stop Selection with Main Power OFF (Pn67).
When the Servomotor is stopped and the RUN Com-
mand Input (RUN) is turned OFF, the Brake Interlock
Signal (BKIR) will turn OFF, and the Servomotor will
turn OFF after waiting for the time period set for this pa-
rameter (i.e., setting × 2 ms).
When the Servomotor is stopped and the RUN Com-
mand Input (RUN) is turned OFF, the Servomotor will
decelerate to reduce rotation speed, and the Brake In-
terlock Signal (BKIR) will turn OFF after the set time for
the parameter (i.e., setting × 2 ms) has elapsed.
BKIR will also turn OFF if the speed drops to 30 r/min
or lower before the set time elapses.
Set whether to use a built-in resistor or to add an Exter-
nal Regeneration Resistor.
Regeneration resistor used: Built-in resistor
The regeneration processing circuit will oper-
ate and the regeneration overload (alarm
0
code 18) will be enabled according to the in-
ternal resistance (with approximately 1% du-
ty).
Regeneration resistor used: External resistor
The regeneration processing circuit will oper-
1 ate, and regeneration overload (alarm code
18) will cause a trip when the operating rate of
the regeneration resistor exceeds 10%.
Regeneration resistor used: External resistor
The regeneration processing circuit will oper-
2
ate, but regeneration overload (alarm code
18) will not occur.
Regeneration resistor used: None
The regeneration processing circuit and re-
3 generation overload (alarm code 18) will not
operate, and all regenerative energy will be
processed by the built-in capacitor.
Set the amount of time required until shutoff is detected
if the main power supply continues to shut off.
