- Single-axis incremental or absolute positioning
- Stored-data, BCD parallel-input, digital-switch, or pulse-train commands
- Rotary-encoder feedback with software semi-closed-loop control
NDS-501B is a NIKKI single-axis digital positioning controller designed for the Digital S-Pack positioning system.
It generates controlled positioning motion from several selectable command sources and applies linear or S-curve acceleration and deceleration while monitoring rotary-encoder feedback.
Before installation or replacement, verify the NDS-501B/BF suffix, command and feedback wiring, 5 VDC supply, mounting arrangement, switch settings, and stored machine parameters.
Availability, condition, price, and shipping time for NDS-501B are confirmed during quotation.
