SERVO ON
The servo amplifier will not operate if the servo amplifier is in a normal state and this servo ON signal is OFF.
SERVOMOTOR
A motor that rotates true to the command.
Servomotors are highly responsive, and can carry out frequent high-speed and high-accuracy starts and stops.
DC and AC types are available, as well as large-capacity motors. A pulse generator accessory for speed
detection is common, and feedback control is often carried out.
SERVO LOCK
In positioning using a servomotor, stepping motor, etc., working power is required to hold the machine at the stop
position.
(The position will be lost if the machine is moved by external power.)
This kind of state is called servo lock or servo lock torque.
SKIP FUNCTION
When a SKIP signal is input, the positioning being executed is interrupted, the motor is deceleration stopped, and
the next positioning is automatically carried out.
STATUS
Data showing the state of the machine. Collectively refers to signals that turn ON when the battery voltage drops,
during OPR requests, during dwell time, etc.
