Speed Control

Contributes to Improved Takt Time with the Highest Level of Speed Control

Max. speed of 4000 r/min
Speed ratio of 2000:1 (Double the ratio of conventional products)
The BXII Series achieves 2 ~ 4000 r/min (with digital setting)*. The speed range has been greatly expanded.

*30 ~ 4000 r/min with analog setting.

Speed regulation: ±0.05% (load/voltage/temperature)

Expanded Speed Control Range

Speed Selection Tailored to Load and Takt Time is Possible

Up to 16 speeds can be set. (Twice as many as conventional products.)

Speed Selection

Position Control

Built-in Positioning Function

Positioning operations are possible with the driver on its own. A control module is not required.

Continuous Rotation in the Same Direction is Possible

The command position and multiple rotation data can be returned to 0 when the command operation exceeds the round setting range parameter. Since the multiple rotation data is returned to 0, continuous rotation in the same direction is possible.

Continuous Rotation

Various Positioning Operations are Possible

3 types of operation function; independent operation, linked operation and linked operation 2.

Torque Limiting

What is Torque Limiting Function?

The setting range of the motor's starting torque (max. instantaneous torque) can be limited to 0~250% in 1% increments.

In addition to suppressing motor torque for safety purposes, this can be utilized for a variety of applications based on the usage conditions.

Torque Limiting

Improved Torque Limiting Accuracy
BXII ±Approx. 10 % (with respect to rated torque)

Torque limiting can be switched ON/OFF with an external signal
(TL input).

Torque Limiting Input

Simple Control

Data Setting is Easy

Digital setting and operation can be done with the driver's control panel. Speed, load factor, current position, operation number, etc. can be displayed. Remote settings are also possible when a control module (OPX-2A) (sold separately) is used. For use with a computer, the MEXE02 software is available to download for free.

Data Setting Display

Easy Wiring

The new I/O connector does not require a screw, which also eliminates the need for soldering or a special crimping tool.

The motor connector and encoder connector can be connected easily.

Easy Wiring

Easy Data Editing and Monitoring

The data setting software (MEXE02) is compatible with Windows 7, vista, XP and 2000. Besides data editing, I/O and operating speed waveform monitoring are possible. USB Cable (CC05IF-USB) sold separately.

Compact, Powerful Driver

Effective Utilization of Installation Space

Optimized arrangement of internal parts has made the drivers compact and slim. Multiple drivers can now be installed in contact with each other, reducing the amount of installation space or increasing the number of axes within the same equipment space.

Compact Driver

Peace of Mind even if a Problem Occurs

Quick response to a problem is possible thanks to the alarm (protective function) and warning that is output prior to an alarm.

Sink/Source Logic can be Selected

It is possible to switch between sink/source logic according to the external controller by changing the wiring.

Permissible Torque without Saturation

The hollow shaft flat gearhead enables permissible torque without saturation even at high gear ratios. The motor torque can be fully utilized.

High Torque

Low Cost

By eliminating parts such as a coupling or belt-and-pulley, the parts cost and labor will also decrease.

Low Cost

Space Saving is Achieved with a Hollow Shaft Flat Gearhead

The output shaft can be coupled directly to your drive shaft without using a coupling. The flexible installation modes, such as installation on either the front or rear face or by using the center shaft, allows you to reduce the size and installation space of your equipment. Since no shaft-coupling parts are needed, the parts cost and assembly man-hours will also decrease.

Electromagnetic Brake Models Available for Vertical Drive

The motor with an electromagnetic brake enables stable speed control even during vertical drive (gravitational operation). When the power is turned off, the motor stops instantaneously to hold the load in place. The electromagnetic brake is automatically controlled via the driver in accordance with ON/OFF of the operation command signal.

Regeneration Unit

During vertical drive (gravitational operation) and when starting and stopping large inertia loads rapidly, external forces cause the motor to rotate and function as a power generator. When that occurs, if the regenerative power exceeds the capacity of the driver to absorb, failure may result. In such cases, the regeneration unit is connected to the drive and the regenerative power is released as heat energy.
