Servo ready
This signal is output when the servo
is ready to turn on (with main power
supply turned on and no alarms
tripped.)
Open collector

ALM
ALME
Alarm
An alarm signal is output when an
alarm has tripped. (This signal is ON in
normal state and OFF when an alarm
has tripped.)
INP
INPE
Positioning complete
This signal is output when the deviation
between the command position and
current position is within the preset
positioning range.
Relay

(Note 1)
Brake release relay
output
When the servo is ON, this terminal
outputs a signal to allow releasing the
brake. (FLIP-X series only)
24V DC
375mA max.
Monitor
output
AO1 Monitor output 1
Outputs speed detection values, torque
commands, etc. as analog signal
voltages for monitoring.
Signals to output are selected by
setting parameters.
These signals are only for monitoring.
Do not use for control.
