Brake Reference - Servo
OFF Delay Time 10ms
0 ~ 50 Brake ON Timing
(Timing in the motor STOP state)
Get the timing in Pn506 when the
machine has mode a minute amount
due to gravity, etc., in accordance with
the brake ON timing.
Sets the brake control output signal (/
BK) and the servo OFF operation
(motor output stop) timing when a ser-
vomotor with brake is used.
In the standard setting, the servo is
assumed to be OFF at the same time
as the /BK output (brake opera-
tion).The machine may move slightly
due to gravity in accordance with the
machine structure and brake charac-
teristics.At this time, it is possible to
lose motion by slowing the servo OFF
operation using the user parameters.
Holding Brake Setting (brake operation
during motor rotation)
To stop the motor during operation, get
the timing in Pn507 and Pn508 so as to
apply the holding brake.
When using a servo motor with brake,
set the brake timing for servo OFF dur-
ing motor operation due to input signal
S-ON (OBC0010) and alarm genera-
tion.
