Flat Torque CurveWide Speed Control Range and Flat Torque

The maximum motor speed of the BLV Series is 4000 r/min. The speed control range has also expanded to cover velocities from 100 to 4000 r/min (speed ratio of 50:1; measured at the motor shaft), thus allowing you to program operations at various speeds from low to high.

 


 

Slim, Yet Powerful Design

A slim body and high output are two key features of a brushless motor. The BLV Series does not disappoint users expecting these attributes. From its space-saving compact body in a frame size of 4.09 in. (104 mm), the BLV produces a high output from 1/4 HP (200 W) up to 1/2 HP (400 W).

Equipped with Functions to Facilitate Battery Drive
  • Capable of driving even if the battery voltage is low
  • A warning output notifies when the battery voltage is low
OPX-2A Extended Functions using Control Module OPX-2A (sold separately)

Functions can be extended and settings shown on a digital display by using a separately sold control module (OPX-2A). It can also be used in RS-485 communication mode.

BLV RS-485

RS-485 Communication System

RS-485 communication lets you set operating data and parameters and enter operation commands. A single programmable controller connects up to 31 drivers and provides multi-axis synchronous starting.
The protocol of the RS-485 communication system supports Modbus RTU, allowing it to easily connect with programmable controllers, touch panels and other devices.

  • FWD input, REV input and other operation commands can also be controlled from I/O.
  • The test operation function is available with the control module (OPX-2A)
  • The internal potentionmeters for Speed, Acceleration/Deceleration and Torque Limiting are still active even when using either the control module (OPX-2A) or RS-485 communication.
