Description
This servo is used as position control servo.
This servo is used as internal speed control servo.
Using external input signal, control can be switched
between position control and internal speed control.
High-resolution encoder of 131072 pulses/rev is used as a
servo motor encoder.
You can switch between gains during rotation and gains
during stop or use an external input signal to change gains
during operation.
Servo amplifier detects mechanical resonance and sets filter
characteristics automatically
vibration.
Suppresses high-frequency resonance which occurs as servo
system response is increased.
Analyzes the frequency characteristic of the mechanical
system by simply connecting a servo configuration software-
installed personal computer and servo amplifier.
Can simulate machine motions on a personal computer
screen on the basis of the machine analyzer results.
Personal computer changes gains automatically and
searches for overshoot-free gains in a short time.
Suppresses vibration of 1 pulse produced at a servo motor
stop.
Input pulses can be multiplied by 1/50 to 50.
Automatically adjusts the gain to optimum value if load
applied to the servo motor shaft varies.
Speed can be increased smoothly in response to input pulse.
Speed can be increased and decreased smoothly.
Used when the built-in regenerative brake resistor of the
servo amplifier does not have sufficient regenerative
capability for the regenerative power generated.
