2. BK signal
Default unallocated output
terminal
The range of parameters
is 0001-0014.
can be assigned to other
output terminals through
P5-44.
Use SO1 terminal output signal to
control brake
3. Switching time of BK signal and S-ON signal
Because of the action delay time of brake, the machine moves slightly under the action of gravity and
so on. P5-07 parameter is used to adjust the time. Delay this time to release the brake after enabling or
lock the brake and delay this time when the enable signal is off.
Note: The setting here is the time when the rotation detection TGON is invalid when the motor is
stopped.
When setting the servo motor with brake, the output signal of the control brake "/BK" and the time of
ON/OFF action of the servo SON signal are shown below. That is, before the output /BK signal lock-in
is opened, the servo motor has entered the power-on enabling state; after not output /BK signal and
brake is locked, the servo motor is disconnected from the power-on state.
Servo OFF before
P5-07 brake locked
/S-ON input
/BK output
4. Setting of brake closing parameters
Brake command
output speed
When the alarm occurs, the motor quickly becomes non-electrified. Because of gravity or inertia
and other reasons before the brake action time, the machine will move. To avoid this situation, the
above parameters need to be set.
