0x03
ON (closed) when the speed of the servo motor is
higher than the set value.
/S-RDY
0x00
ON (closed) when servo ON (/S-ON) signal is
acceptable.
/CLT
0x04
Torque limit ON (closed) when the motor output
torque is limited.
/VLT
0x05
In the speed limit, the motor speed is ON after
closing the speed limit (closed).
/BK
0x06
Brake interlocking, the output of the motor is ON
during operation. Refer to “Retaining the brake” for
timing details.
/WARN
0x07 Warning output.
Speed
/V-CMP
0x02
Consistent speed output ON when the speed of the
servo motor is the same as the command speed
(closed).
Position
/COIN
0x01
Positioning completed output ON (closed) when the
difference between the command pulse number
and the servomotor movement amount (position
deviation) is lower than the position reach range.
/PSELA
0x09
Command pulse override switching can be
switched to operate with the value of the input
command pulse n times (Pn203).
/NEAR
0x08
Positioning close, output ON (closed) when the
difference between the positioning command pulse
number and the servo motor movement amount
(position deviation) is lower than the position
proximity signal.
