Name
You can allocate the output signal to use with
a parameter.
(Controls the brake. The brake is released
when the signal turns ON (closes).)
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.)
Output the encoder divided pulse output sig-
nals with a 90° phase differential.
Outputs the origin signal once every encoder
rotation.
This is the 0-V signal for the control circuits.
Connected to the frame ground if the shield of
the I/O Signal Cable is connected to the con-
nector shell.
