Fuji's Compact servo system, packed with advanced control technologies, meets new industry standards.

The new FALDIC-a series has come onstage with enhanced fundamental functions and a variety of other useful functions such as an easy-to-operate PC loader and real-time tuning of the mechanical systems. These help shorten your setup time as well as improve your machine's performance.

  
 
     
 
Features of the FALDIC-a

FINE
Frequency response at 600Hz and a settling time of 1 ms provide amazing control capability. The servo motor incorporates a real-time tuning function to automatically adjust the gain even when the moment of load inertia fluctuates.
 
Flexible
The servo motor, equipped with a 16-bit serial encoder which can be used for both incremental and absolute position feedback systems, requires less wiring and keeps the motor wow at low level.

The encoder connects with four cables: two for power and two for signals. (To construct an absolute position feedback system, however, two other lines are required to connect with the battery.)

The motor can be operated in combination with the encoder without changing the encoder settings, even though such combination is not specific as the standard combination.
 
Friendly
From the selection of a suitable servo motor capacity, to test operation of the motor, maintenance and inspection, as well as diagnosis of alarms, the personal computer loader helps navigate you through all processes. The servo amplifiers radiate less heat horizontally and can be installed side by side with very little or no clearance between them. (If they are completely fitted to each other, however, the cyclic duty factor will be reduced to 80%ED.)
 
Facility
The servomotors are so compactly designed that they can be mounted even in a small area. Servo amplifiers are available in three types; velocity control, linear positioning and rotation angle index type. Choose one according to your needs. The servomotors meet foreign standards. (The standard model meets CE marking and is planning to achieve UL/cUL standards.)
 
Servo Motor
16-bit serial encoder
The servomotor is standard-equipped with a 4Mbps serial encoder that can generate 65536 pulses/revolution. These components are connected with only four wires.
 
Specifications common to 50W to 5kW
 There are two types of motors: a cubic type (ranging from 100W to 2kW) with a short depth and a slim type with a small flange. Using both types, you can select a motor with a brake or a gear head.
 
High-speed response and low motor wow
 The power rate of the slim type is 65kW/s. The motor returns to the rated speed by accelerating or decelerating in approximately 2ms. (0.4kW servomotor, no load at shaft end). A 16-bit serial encoder keeps the motor wow at a low level by generating 65536 pulses.
 
Servo Amplifier
Servo amplifier can be used for incremental and absolute position feedback
An absolute position feedback system can be constructed by connecting a battery to the servo amplifier.
 

Automatic detection of servomotor type
The amplifier detects the motor type (cubic or slim) and the motor capacity. Therefore, you can operate the motor simply by supplying power to the amplifier.
- The servomotor and the servo amplifier are ranked at the same capacity level.
- The servomotor is ranked higher or lower than the servo amplifier by one capacity level (3-phase 200V series).
 

High-speed response
The amplifier detects changes in the status of the ON/OFF control signal in 1ms. The amplifier quickly responds to the signal change sent from the host control unit. The amplifier achieves a frequency response of 600Hz by combining with a low inertia motor. Personal computer loader.
 
Personal Computer Loader

Monitor
When you connect the personal computer loader and the servo amplifier, you can continuously monitor the servo amplifier operating condition. Both real-time trace and historical trace are available as a monitoring method.

 
Application Examples
(FALDIC-a series are used in the following applications)
Control method: synchronized operation, linear positioning

PC board inspecting machine
This machine moves the printed circuit board sequentially so that a camera can properly capture the portion to be inspected. The board moves in the registration order of position data.
 
Control method: synchronized operation
Horizontal pillow-type packaging machine
This machine packages a piece of bread or the like one by one. The machine pulls and rolls a sheet of film like a pillow, packages a product in it and then seals and cuts the film. The servo system determines the sealer and conveyor positions in synchronization with the film pulling motion.
 
Control method: linear and rotary positioning

Staggered holes drilling machine
This machine drills holes in staggered positions on a pipe. The servo system controls the vertical travel and rotation speed of a drill and the front-back movement and rotation of a pipe.
 
Control method: rotation angle indexing
ATC (automatic tool changer)
This unit automatically changes the tools on the machine tool. When a tool number is given, the servo system indexes the relevant tool to the tool change position. The system can index the tool by rotating the turret either in one direction or in whichever direction closer to the tool change position. On completion of indexing, the ATC mechanically locks the turret.
