(denominator), but should be set to a ratio within the range shown above.
Common
Auto tuning
The load inertia is identified in real time by the driving state of the motor operating according
WRWKHFRPPDQGJLYHQE\WKHFRQWUROOLQJGHYLFHDQGVHWXSVXSSRUWVRIWZDUH´3$1$7(50µ
The gain is set automatically in accordance with the rigidity setting.
Division of encoder feedback pulse
Set up of any value is enabled (encoder feedback pulses count is the max.).
Protective
function
Hard error
Over-voltage, under-voltage, over-speed, over-load,
over-heat, over-current and encoder error etc.
Soft error Excess position deviation, command pulse division error, EEPROM error etc.
Traceability of alarm data The alarm data history can be referred to.
