ALPHA 7 Fuji Drive and Automation Electric Servo System
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 the 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 Fuji Drive and Automation 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 SBC (Safe Brake Control) *Option
The SBC signal is an output signal for controlling an external brake and operates synchronously with STO.
Maximize performance by using MICREX-SX in conjunction
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 MICREX-SX eliminates the need for 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 the 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
Design and features of ALPHA 7 Electric Fuji Drive and Automation
Easily analyze the cause of alarm occurrence
When an alarm occurs, the system displays the content of the alarm as well as related data such as the speed and torque at the time of alarm occurrence. This allows you to accurately analyze the cause of the alarm.
Life prediction and preventive maintenance features
You can check the status of the servomotor from the controller, so you can perform maintenance at the appropriate time. In addition, the system predicts the life of the following consumables and sends the data to the host controller for proactive failure prevention.
