The dramatically evolved control functions significantly increase the productivity

To gain the maximum advantage of constantly evolving high-tech industrial equipment, a servo system with high responsiveness and high precision is essential. With its dramatically evolved control functions, Fuji Servo System ALPHA7 raises the speed and precision of drive control to the highest level in the industry. It supports a broad range of monitoring functions and has reached the next level of safety. It meets the highest level of customer requirements for productivity improvement, cost reduction, and safety.

High-speed and high-precision control is realized by the basic performance at the highest level in the industry

Speed and frequency response at 3.2kHz realizes ultra-high-speed control
Fuji's proprietary control algorithm achieves a speed and frequency response at 3.2kHz, the highest level in the industry. This reduces the tact time, enabling high-speed control.



Maximum instantaneous torque of 350%* enables response to high-speed commands
The maximum instantaneous torque of the servo motor is now as high as 350%.
* This is applicable only to certain models.



The 24-bit fine resolution INC/ABS encoder significantly improves the precision of control
The encoder resolution is now as high as 24 bits. This provides much higher control precision than before, enabling high-precision control.



Safer operations are ensured by various safety functions
Standard equipment includes the STO function defined in the international standard IEC61800-5-2. In addition, the WSU-ST1 option adds support for SS1, SLS, SBC, and SSM. These safety functions can be easily configured with parameters.

Equipped as standard with STO (Safe Torque Off)
Upon receiving an input signal from external equipment, the servo system shuts off the output from the servo amplifier and enters into free-run mode.



Support for SS1 (Safe Stop 1) *Option
Receiving an input signal from external equipment, the servo system operates the STO function when the speed is reduced to the specified value or the specified period of time elapses.



Support for SLS (Safely Limited Speed) *Option
The servo system monitors whether or not the speed limit value is exceeded and, if exceeded, enters into STO mode.



Support for SSM (Safe Speed Monitor) *Option
The servo system outputs the SSM signal when the specified speed is exceeded.



Support for SBC (Safe Brake Control) *Option
The SBC signal is an output signal for controlling an external brake and operates synchronously with STO.



An example system configuration that uses Alpha 7

High-speed serial bus (compatible with SX bus) VS/LS Types
You can easily build a highly functional motion control system that includes synchronous and interpolation control.



Gain the maximum advantage of Alpha 7 with optional peripheral equipment and software

Motion controller MICREX-SX
High-speed processing enables the control of constantly evolving high-tech machines.
It is possible to perform high-speed processing with a program scan cycle as fast as 0.25ms and I/O refreshing at intervals of 1ms (8192 points). You can build a particular motion control system in a short time by choosing from the rich set of FBs (function blocks) and appropriately combining FBs.

Programmable operation display MONITOUCH V9 series
Provides an intuitive user interface and yet the ability of remote control in a network environment.
Supports the VNC server functionality and allows you to remotely monitor and operate MONITOUCH installed at the field from your tablet PC. If an Internet connection environment is available, you can easily implement remote connections in a secure VPN environment.

General-purpose interface VV Type
A single unit allows:
- Positioning run (immediate data operation) based on Modbus-RTU
- Positioning run (with 31 positioning data points) based on Di/Do signals
- Position, speed, and torque control run based on pulse train/analog input



Open Network (with support for EtherCAT) VC Type
EtherCAT applications (with support for six different control modes and for synchronous (DC, SM2) and asynchronous (FreeRUN) modes)



Build and tune your system more easily and speedily

Transparent communication allows you to configure multiple amplifiers from a single central location
You can use the transparent communication feature to configure the parameters of multiple servo amplifiers from a single PC via the motion controller. In addition, connection with Fuji's MONITOUCH allows Wi-Fi communications with servo amplifiers.

A single CPU performs both sequence and motion control
Adding a single unit of MICREXSX eliminates the need of a module dedicated to motion control, thus significantly reducing the initial cost. Also, work efficiency is dramatically improved by supporting both sequence and motion with a single programming tool*.
*SX-Programmer Expert (D300win)

Directly connectable with a single SX bus and easy to wire and extend
Just a single bus cable completes the connection between the controller and servo. When you add an additional control axis to allow for the extension of the machine, you can connect it in a one-touch fashion using a bus cable.

Broad range of functional software "FBs" raises development efficiency
Various software parts, FBs (function blocks), are available free of charge. By appropriately combining FBs, you can build a motion program for a large-scale system in a short time. If you have trouble in developing programs, consult Fuji for support.

Various features that allow standalone use of Alpha 7

Automatic servo adjustment in tuningless mode
In tuningless mode, you do not have to manually adjust the responsiveness (gain) because the servo system automatically does so. You no longer spend time on tuning at start-up time.

Finer adjustment is possible in auto tuning mode
In auto tuning mode, the servo amplifier automatically adjust the responsiveness (gain). This mode allows finer control than tuningless mode.

Highest precision requirements can be achieved in manual tuning mode
This mode is intended for use with machines that require high precision. It allows you to optimize multiple parameters at once, enabling high responsiveness (gain) adjustment.

Test-run the machine before completion of a program using the pattern run feature
You can adjust the machine and servo before completion of a program for the controller.

Test-run a program before completion of the machine using sequence mode
You can run a controller program before completion of the machine, so you can debug programs more efficiently.

Simplify your system using the built-in programmable positioning feature (applicable to the LS type only)
You can easily perform positioning run, using pre-registered positioning data. You can register positioning data for up to 31 points in VV type and up to 99 points in LS type. You can run the system by just selecting a program number and issuing a start command from the host controller. This feature is most useful for the purposes of inching and repetitive operations.

Evolved control functions contribute to streamlining of operation and stabilization of quality

New damping control suppresses the vibration at equipment edges
The introduction of a new control algorithm reduces the vibration at the edges of the equipment to one tenth, compared with the conventional damping control (used in our products). Support for models with three inertia systems makes it possible to control low-frequency vibrations at two points concurrently.

The interference detection feature detects a collision, etc. and prevents breakage
The servo amplifier detects interference on the equipment (such as a collision with an edge of the machine) and operates to mitigate the shock to the machine when a collision occurs. This feature helps prevent damage to the equipment and reduce load on it.
* Protection may not be complete depending on the operation type.

The cogging feature ensures smooth operation
Since interference due to cogging of the servomotor is detected and compensated, speed ripples due to cogging can be reduced and smooth operation can be ensured even if the equipment does not support the increase of the speed loop gain.

Maximum input pulse frequency of 4MHz
The system can support input frequencies from the host controller until the maximum frequency of 4MHz is reached. This allows a finer amount of travel per pulse, thus enabling positioning operation at a higher precision than before.
- Differential input: Max. input frequency ≤ 4.0 [MHz]
- Open collector input: Max. input frequency ≤ 200 [kHz]
However, the VS type supports only the counter feature and it cannot support pulse train operation.

The notch filter feature suppresses the resonance of the machine
Now five notch filters are incorporated instead of two, further improving the machine resonance suppression feature.

The motor status can be monitored from the host controller
The system detects machine resonance and automatically configures the notch filters. While the auto notch filter feature is on, the system constantly performs detection and calculation, thus being able to respond even to moment-to-moment changes in resonant frequency.

One of three motor stop methods can be selected
You can select "rapid deceleration stop", "DB stop", or "coast-to-stop" when an alarm occurs, when the main power is off, or when the servo-on signal is off. Since limiting output torque at desired value is possible even if rapid deceleration stop is selected, impact shock to the machine can be reduced.* One of three motor stop methods can be selected
* However, it is enabled when the control power supply is input.

A homing program can be easily configured
Several homing features allow simple configuration by just combining servo parameters.

Interrupt positioning feature (except for EtherCAT type)
You can easily perform positioning run, using pre-registered positioning data. You can register positioning data for up to 31 points in VV type and up to 99 points in LS type. You can run the system by just selecting a program number and issuing a start command from the host controller. This feature is most useful for the purposes of inching and repetitive operations.
