ENS: Encoder 1 (motor end) = 12V, Hiperface/1Vpp/TTL/IndraDyn fully compatible

EN1: Encoder 2 (external / second feedback) = 5V incremental encoder (TTL/1Vpp), 15-pin D-SUB

NN: Safety = no integrated STO safety function

S: Panel = standard single-line LED + 4 keys

NN: Special functions = none

FW: Pre-installed official firmware + authorization, plug-and-play

III. Key Features of S3 (SERCOS III)

Ethernet hard real-time: Based on IEEE 802.3, 100 Mbps, dual RJ45 redundancy

High-speed synchronization: Multi-axis synchronization period up to 250 µs, jitter < 1 µs

Topology flexible: Supports linear / ring / star, up to 254 nodes

Compatible TCP/IP: Parallel transmission of real-time and non-real-time data, no tunneling required

IV. Encoder Configuration (ENS + EN1)

ENS (motor end): 12V power supply, compatible with MSK/MHD/MAD etc. IndraDyn motors, supports absolute / incremental feedback

EN1 (external): 5V incremental encoder, used for external position feedback, tension control, synchronous axis (such as spindle + feed)

Typical usage: ENS at the motor end as closed loop, EN1 connected to external grating ruler / encoder to achieve full closed-loop control
