AC servo drive packages with brushless motors and full digital servo drives.

Features of the servo drives

• Compact drives for control cabinet installation
• For direct connection to 230 V_AC or 3 × 400/480 V three-phase mains
• High dynamics and control quality through signal processor for digital control of current and speed (controller cycle time 62,5 µs)
• Rapid acceleration, deceleration and reversing of the servo motor by momentary current increase to up to three times the rated current
• Position control loop integrated (micro-controller cycle time 1 ms)
• Technology functions (positioning control etc.) integrated
• Various operating modes, including interpolated position mode
• On request with integrated positioning control with 500 program command blocks
• Easy wiring
• Switching frequency 8 kHz or 16 kHz selectable for optimum dynamic characteristics and small motor power loss
• Comfortable installation using a personal computer with the SPP Windows software
• Access to drive parameters via drive server (OPC)

Features of the servo motors
