above, SLS1 to SLS4 status is OFF.
: Turns ON when an error relating to safety
communication occurs in the servo amplifier. Other than
the above, Error status1 is OFF.
: Turns ON when a command signal for a safety
observation function which cannot be used is input in the
servo amplifier parameter settings. Other than the above,
Error status2 is OFF.
: Status signal for motor holding brake. Turns OFF when
the STO function of the servo amplifier is operating and
power supply to the brake is shut-off. Other than the
above, SBC status is ON.
: Turns ON when the SOS function of the servo amplifier
is operating with the SS2 function of the servo amplifier.
Other than the above, the SOS status is OFF.
: Turns ON when the motor speed is less than or equal to
the SSM speed set at the servo amplifier. SSM status is
OFF when SSM function is disabled.
