S6 Spindle Servo Drive
The S6 family is a spindle-specific CNC servo drive supporting asynchronous and permanent-magnet synchronous motors. Analog/pulse S6, EtherCAT S6C and M3 S6M are distinct interface variants. Select motor/spindle encoder compatibility, current rating and braking together.
Technical specifications
Ratings refer to the linked document revision. Confirm the nameplate, motor current and operating conditions for the exact selection.
