CAUTION: Be careful to avoid specifying a braking time that is long enough to cause
motor overheating. If you use DC braking, we recommend using a motor with a built-in
thermistor, and wiring it to the inverter's thermistor input (see "Thermistor Thermal
Protection" in chapter 4). Also refer to the motor manufacturer's specifications for
duty-cycle recommendations during DC braking.
DC braking performance at start can also be set separately ( and ).
And carrier frequency of DC braking performance can also be set separately ().
CAUTION: Be careful to avoid specifying a braking carrier frequency that is high
enough to cause inverter and motor overheating. If you use DC braking, we recommend
using a motor with a built-in thermistor, and wiring it to the inverter's thermistor input
(see "Thermistor Thermal Protection" in chapter 4). Also refer to the motor
manufacturer's specifications for duty-cycle recommendations during DC braking.

Description
Three options; select codes:
Disable
Enable during stop
Frequency detection
The frequency at which DC
braking begins,
range is from the start
frequency () to 60Hz
The delay from the end of
controlled deceleration to start
of DC braking (motor free runs
until DC braking begins),
range is 0.0 to 5.0 sec.
Level of DC braking force,
settable from 0 to 100%
Sets the duration
braking, range is from 0.0 to
60.0 seconds
Two options; select codes:
Edge detection
Level detection
Level of DC braking force at
start, settable from 0 to 100%
Sets the duration
braking, range is from 0.0 to
60.0 seconds
Carrier frequency of DC
braking performance, range is
from 2.0 to 15.0kHz
