The EMP400 Series and SG8030J controllers for step motors
offer a wide range of features and functions to meet the needs
of your application.

The EMP400 Series controllers allow easy programming using simple commands. The dual axis model provides coordinated moves via linear interpolation. Various motion profiles can be achieved by using up to 32 sequence programs. 1 program can be dedicated as a STARTUP program.
Various operation commands are provided for positioning operation, return-to-home operation and dual axis linear interpolation functions. The operator only needs to set the parameters.
A series of operation patterns can be programmed using dedicated commands. This is an ideal function for distributed system control.
General-purpose I/O signals are provided in addition to dedicated I/Os such as pulse output and limit-sensor input. Synchronization with peripherals is also possible.

The time between a START signal input and a pulse output is 2 ms or less.
The jerk-limit control function allows you to set a shorter acceleration/deceleration time compared with the use of linear acceleration/deceleration patterns. This reduces the overall positioning time.
What is jerk-limit control?
This term refers to the acceleration/deceleration patterns used to ensure the smoothness of speed change at the start of operation or when the machine enters a constant-speed mode from an acceleration mode. Since speed can become smoother, vibration is reduced.
Supports both incremental modes (travel amount) and absolute mode (absolute-position).

Two axes are controlled simultaneously, allowing direct movement to a target position.
The amount of travel can changed by jogging the load into position via the optional OP300 interface.

With the SG8030 Series, all operation including data setting can easily be performed using the four touch-screen buttons on the top panel. In addition, the number of signal lines is reduced to a minimum for easy connection.
The "Jerk Limiting Control" function effectively minimizes vibrations during motor drive and stop. This is especially useful in applications such as driving a belt pulley, to ensure smooth motion of transported works.
In addition to the 2-pulse output mode, the controller can also provide 1-pulse operation mode, which makes it compatible with a wide range of motor drivers.
The unit is very compact, measuring only 1.89 (W) x 1.89 (W) x 3.3 (H) in. [48 (W) x 48 (D) x 84 (H) mm].
In "Sequential Positioning Operation", the start signal always causes execution from step No. 1 in a preselected sequence.
In "External Signal Operation", when the CW scan (or CCW scan) signal goes ON, operation starts. When the signal goes OFF, slowdown stop occurs. This is useful for moving the work manually to a desired position.
