Details

Designed for low-speed, high-precision motion, the L7050 series combines a hollow-shaft form factor with stable, smooth output.

Material and drive design details focus on torque density, long bearing life, and accurate current sampling for reliable control.

CAN/RS485 bus communication and absolute encoder feedback support precise speed and position control with one-time calibration.

Clear pin labeling and an onboard ID switch simplify wiring multiple motors on a CAN or RS485 bus.

PC configuration tools help tune control modes and select the encoder resolution option (15-bit or 18-bit) for the required precision.
