SANYO DENKI Develops 4-Axis Integrated Driver
for Closed Loop Stepping Systems
Enables flexible system configuration and takt time reduction
February 13, 2017
SANYO DENKI CO., LTD. has expanded its lineup of SANMOTION Model No.PB closed loop stepping systems with the addition of a 4-axis DC stepping driver with built-in EtherCAT interface.
Capable of controlling multiple motor axes simultaneously, it is suitable for applications such as semiconductor manufacturing equipment, laser cutting machines, and general industrial machinery.
Features
1. High-speed fieldbus EtherCAT interface equipped
This driver comes equipped with a fieldbus1 that allows for 100 Mbps high-speed and highly reliable communications. This has shortened the communication cycle time by 4 times2 or more that of our current model3, achieving finer and smoother motion of the embedded device.
2. Encoder variations available for simplified maintenance
In addition to an incremental encoder, a battery-less absolute encoder is also available.
This encoder doesn’t require battery replacements, thus the maintenance of devices can be simplified.
3. Flexible system configuration
Different encoder types can be equipped with each motor axis, enabling configuration of systems matched to device structure.
The driver can automatically identify the encoder types, saving time on setup. (patent pending)
4. Shortens motion completion time of devices
Any commanded motion such as position settling and continuous rotation can be controlled without delays to position commands.4
1 Fieldbus is an all-digital, serial communications protocol used for communications among field devices and to the controller.
2 Minimum communication cycle time: 0.25 ms (1 ms for the below current model).
3 When compared with our current model PB4D003E2D0.
4 Low-deviation closed loop control
