J Brake ON Timing
If the machine moves slightly due to gravity when the brake is applied, set the following
parameter to adjust brake ON timing:
Cn-12 BRKTIM
Time delay from the
time a brake signal is
output until servo OFF
status occurs
Unit:
10 ms
Setting
Range:
0 to 50
Factory
Setting:
0
For
Speed/Torque
Control and
Position Control
This parameter is used to set output timing of
brake control signal /BK and servo OFF operation
(motor output stop) when SGMj servomotor with
brake is used.
With the standard setting, the servo is turned OFF when /BK signal (brake operation) is
output. The machine may move slightly due to gravitation. This movement depends on
machine configuration and brake characteristics. If this happens, use this parameter to
delay servo OFF timing to prevent the machine from moving.
For brake ON timing during motor operation, use Cn-15 and Cn-16.
