Compatible System and Applications
The SGM7J-01AFA61 is normally paired with a compatible 100 W Sigma-7 SERVOPACK such as an SGD7S-R90A capacity. The complete SERVOPACK suffix must be selected according to the controller interface, safety requirements, encoder support and machine communication architecture.
Typical applications include inspection equipment, compact feeders, electronic assembly machinery, labelling systems, measuring devices, small packaging axes and light robotic positioning mechanisms.
Maintenance and Replacement Notes
Confirm the complete SGM7J-01AFA61 designation, including the incremental encoder and final keyed-shaft configuration. Verify the shaft diameter, key dimensions, threaded center hole, flange, connector orientation and mounting depth.
Check the SERVOPACK capacity, firmware, motor parameters, encoder cable, motor power cable, coupling and machine travel limits. This model does not include a holding brake and should not directly support a suspended load after servo power is removed.
