Suppresses mechanical vibrations to the maximum extent. |
 Equipped with a "Vibration Suppressing Control Function" which is an effective countermeasure for suppressing vibration of the tips of robot arms, etc. |
Fuji's original vibration control function (Patent pending)
In high tact operation of mechanisms with low rigidity, such as the tips of robot arms, suppression of arm tip vibration is a major factor in shortening tact time. In the FALDIC-α series, Fuji’s original Vibration Suppressing Control Function is standard equipment. It reduces vibration in machines with low rigidity and realizes high machine tact. |

| Equipped with a notch filter and servo analysis function. |
Notch Filter
This function is for the purpose of reducing machine resonance. By setting the data on the resonance point, which differs in each machine, as a parameter in the servo amplifier, the machine resonance occurring in that point can be reduced. |
Servo Analysis Function (Option)
In order to utilize the Vibration Suppressing Control Function and Notch Filter, etc. effectively, it is necessary to analyze the resonance frequencies that are inherent in each machine. If the Servo Analysis Function offered in the optional personal computer loader is used, it can analyze the data for the machine system simply, eliminating the needs for complicated calculations and adjustments which are dependent on intuition. |

(Data acquisition example. The notch filter setup values and vibration suppressing control setup values can be easily determined.) |

Designed for high performance and high precision. |
| Command following servo (positional deviation ≈ zero). |
Positioning settling time is 1ms or less.
Through the newly developed feed forward control which compensates for servo delay, operation even during acceleration and deceleration can be done with positional deviation almost zero. A positioning completed signal can be output virtually simultaneously with the end of the command pulse (within 1ms) . |
| Frequency response 600Hz |
| Frequency response 600Hz has been achieved. As a high-performance servo system, high-tact operation and high-frequency acceleration/deceleration can be realized. |

New functions pursuing easy use are provided (VVX type). |
| Inverter-like analog voltage inputs between 0V and 10V are supported. When an input voltage comes close to 0V, servo lock automatically occurs and deviation from the stop position due to analog voltage drift is eliminated. |
|
|
| The scope of auto tuning is further widened and a large inertia load that is 100 times larger as a motor inertia moment ratio can be supported. When specifying a gain adjusting value, you can use the up/down key on the touch panel to change the value continuously during operation (test run mode Fn010). Tuning can be easily made with an analog sense. |
|
|
| The output position of the Z phase (marker signal) used for return to origin can be arbitrarily set with a parameter. Adjustment of the Z phase and origin limit switch that has been made mechanical is unnecessary. Z-phase pulse adjustment can be easily made for motor installation or replacement. |
