BX Series
OPERATING MANUAL FOR
EXTENSION FUNCTIONS
AC Servo Motor

2
1. Introduction
This operation manual describes how to use the extension functions of the AC servo motor
BX series using the data setter OPX-1. Before you read this operation manual for extension
functions, read the operation manual for BX series to become thoroughly familiar with basic
operation procedures of the driver. After learning the previous information, read this manual
describing the functions to be extended by the data setter OPX-1.
Major functions to be extended by the System Upgrading Tool Data
Setter OPX-1
In addition to the speed control mode function of the main unit of the BX series driver,
the equipment provides the rotary speed digital setting function and position control
mode function.
Only the speed control mode (when you do not use the data setter
OPX-1)
Speed setting range: Analog two types 30 to 3,000r/min
Slow start time setting range: Analog 0 to 15sec.
Slowdown time setting range: Analog 0 to 15sec.

●Digital speed setting Page 13
Speed setting range: 0 to 3,000r/min
The equipment offers you a function to set motor speed in increments of 1r/min, in
addition to the analog setting function using the internal and external potentiometers of
the driver.
●Speed control mode Page 13
Provides a function to set a maximum of 8 step speed settings.
･Analog 2-step speed setting (driver) + digital 6-step setting, or
･Digital 8-step setting
●Position control mode Page 15
Provides positioning (indexing) operation with the preset motor movement, return to
mechanical home position (home operation) and return to electrical home position
(return).
Position control range: -8,388,608 to +8,388,607 steps (500 steps/rotation)
Number of index points: six
●Digital setting of slow start time and slowdown time Page 14
Slow start time setting range: 0 to 30sec.
Slowdown time setting range: 0 to 30sec.
Slow start time and slowdown time shared by both speed control mode and position
control mode can be separately set in increments of 0.001sec. directly.
●Torque limiting function Page 17
Allows a torque limit value to be set for digital and analog speed settings. You can set
the torque limit value individually for digital speed settings. The torque limit value can
be expressed in percentage based on the instantaneous maximum torque of 100%.
●Servo lock function at motor standstill (speed control mode) Page 14
Allows the use of servo lock to be selected.
●Operation monitor function Page 30
Permits the following operation items to be monitored in the monitor (MON) mode.
･Speed
･Position counter
･Torque
･Alarm code
･Alarm history (up to latest 10)
●Data copy function Page 41
Allows the data set on the data setter OPX-1 to be loaded into multiple drivers, and
enables the driver data to be saved into another data setter OPX-1.
The data setter OPX-1 has four banks as data areas to permit four types of operation
data to be stored.
