  • Because direct connection to hosts such as PCs and PLCs is possible for control, a dedicated transceiver is not required.*1

*1: When using a PC for control, the dedicated software MOD-COM is required. The dedicated software is available free of charge. Please download from the NBK website. (https://www.nbk1560.com/products/mechatronics/positioning_unit/download/mod-com/) Based on the dedicated software functions, a maximum of 1,000 types of setups can be registered.

  • Setting is possible via button operation on the main body, enabling single-unit use without connection to a host. The 7-segment display enables confirmation of the current position and target position.

  • Batch control of up to 32 units is possible.*2

*2: When connecting multiple units, the use of the separately sold repeater hub EORP-200 (EORP-200) enables easy wired connection and reduces wiring work.

  • Mounting can be completed simply by replacing the installed operation handle with EPU-210. Compared with the use of a combined handle and indicator, it is thinner and more compact.

  • IP65 dust-proof and waterproof structure. It can be used safely even in environments where it may be exposed to dust or water.
  • The connection method is RS-485 (Modbus RTU).
  • Cable terminal specifications can be selected by the product code. When using the repeater hub EORP-200 (EORP-200), select the connector type.
