3.1 Nm — what that torque rating means for your axis
The SH30703P11A2122 is a 3.1 Nm servo motor from Schneider Electric — that torque number is the continuous stall rating at rated speed, so it tells you the holding torque and the steady-state load the motor can carry without tripping the drive's I²t limit.
No pin-compatible alternative exists in the Schneider servo family that drops into the same mounting footprint without a drive parameter re-tune.
