Bit Data Contents
Control ON Lights up when control power is turned ON.
BB Lights up with base block and goes out when servo is turned ON.
TGON Lights up when the motor rotating speed exceeds TGON level
(standard setting: 20 r/min).
IN−A input
Reference pulse input
Lights up if IN−A higher than TGON level was input. (At speed
control mode)
Lights up during inputting reference pulse (At position control mode)
IN−B input Lights up if IN−B higher than TGON level was input. (At position
control mode)
Power ready Lights up when power to the main control circuit is supplied.
