Brake Output
You can allocate the output signal to use with
a parameter.
(Controls the brake. The brake is released
when the signal turns ON (closes).)

Servo Ready Output
You can allocate the output signal to use with
a parameter.
(Turns ON (closes) when the SERVOPACK is
ready to acknowledge the /S-ON (Servo ON)
signal.)
