Modbus / RS-485 Integrated Stepper Motor, Microstepping Driver and Controller

.
Modbus / RS-485 Integrated Stepper Motor

FLEXModbus / RS-485 Integrated Stepper Motor, Driver and Controller - PKA Series

This DC input integrated 0.72° stepper motor combines the high performance of a 0.72° stepper motor with a built-in microstepping driver and controller (stored data) type. The built-in controller increases the system configuration flexibility and ease of use.

FLEX is the generic name for products that are used for Factory Automation (FA) network control via I/O control, Modbus (RTU) control, or a network converter. FLEX products enable easy connection via RS-485, easy control and reduce the complexity of system configuration.

Integrated Stepper Motor Simplifies Motion Control

This integrated 0.72° stepper motor features a built-in controller (stored data) type, microstepping driver and high performance motor integrated into one compact package.

There is no wiring needed between the controller,driver and motor, providing easy motion control of the high performance 0.72° stepper motor.

The controller and driver are integrated onto the 0.72° high performance stepper motor. Since there is a built-in controller there is no need for a pulse generator. The system is simplified and requires less wiring.

Integrated Stepper Motor

Higher Performance Stepper Motors

By combining the high performance motor with a built-in microstepping driver and stored data controller, superior noise and vibration reduction can be easily achieved.

Low Vibration

 

Reduces the Burden on the Master Controller

A positioning function is built in, ensuring that the traveling amount, speed, and other operating data is retained in the motor. It is also equipped with a variety of other operation functions in addition to the positioning operation, such as continuous operation and a return-to-home operation. This contributes to a reduced load on the programmable controller and a simplified program.

Positioning Operation

The motor's operating speed and traveling amount are set in the operating data and operations are performed in accordance with the
selected operating data.

Linked Operation

If the operating data is set to "linked", continuous positioning with the
following data number is possible with one START signal.

[Linked Operation]
If data No. 01 is selected and the START input, linked driving from data No. 01 to No. 03 is performed without the motor stopping.

Linked operation

[Linked Operation 2]
If data No. 01 is selected and the START input, the data No. 01 operation is exectured. After that, it is stopped for only the set dwell time1 and then the operations from data No. 02 to No. 03 are executed. Operating data with a different rotation direction can also be linked.

1Dwell time is the wait time until the next position operation starts.

Linked operation

Sequential Operation

If the operating data is set to "sequential positioning", positioning of the next data number is performed in sequence every time a START signal is input.

Speed Control Operation

The motor operates continuously while a FWD signal or RVS signal
is input. Because it operates at the speed of the operating data
set beforehand, multistep speed-change operation is possible by
changing the data number.

Data

Return to Home Operation

Equipped with a sequence for return-to-home operation that reduces
the burden of the host (master controller) and the hassle of combining
programs or sequences. A separate sensor is required.

System Configuration

All necessary cables are included with the package. RS-485 cable sold separately.

Couplings / Brackets

Flexible Couplings

Flexible Couplings

This three-piece coupling adopts an aluminum alloy hub and a resin spider. The simple construction ensures that the high torque generated by a gear motor can be transmitted reliably. The proper elasticity of the spider suppresses motor vibration.

Motor Mounting Brackets

Mounting Bracket

Mounting brackets are convenient for installation and securing a stepper motor or geared stepper motor.
