Outline
Prevents a moving part from colliding with the equipment.
Prevents the servo motor from outputting a higher torque than the
specified value.
Prevents the servo motor from operating faster than the specified
speed.
Outline
Diagnoses mechanical parts failure of the drive system.
Use this function to check the service life of the servo amplifier.
Diagnoses encoder communication circuit failure.
Detects disconnection of the main circuit and the servo motor power
supply wires.
Outline
Prevents the equipment from being stopped by an instantaneous
power failure or a vibration.
Use this function to comply with SEMI-F47 standard.
Outline
Generates 32767 or more revolutions from the home position in the
absolute position detection system.
Outline
Stores data at alarm occurrence. The stored data can be used for a
cause analysis.
Sends linear encoder data to the servo system controller via the servo
amplifier.
Accurately latches the positions at the rising and falling edges of TPR1
(Touch probe 1), TPR2 (Touch probe 2), and TPR3 (Touch probe 3),
and detects them with precision of 1 μs. To latch the current position,
turn the touch probe signal on.
Outputs the position information of the servo motor or the load-side
encoder as A/B/Z-phase pulses. Use this function to execute
synchronous control or other operations.
