Structural Characteristics: Panel-mount or DIN-rail mountable form factor. The drive features front-panel LED status indicators, connector access, and MMC card slot. The compact design integrates EMC filtering and braking resistor management internally.
Working Principle: The S700 series uses advanced digital servo control algorithms with nested current, velocity, and position loops. The DSP processes feedback signals from the connected encoder or SFD, calculates the required motor current, and generates PWM signals for the IGBT power stage. The fieldbus option card handles real-time communication with the host PLC or motion controller, receiving motion commands and returning status information.
Installation Requirements:
- Install in a closed control cabinet with adequate ventilation
- Maintain cabinet internal temperature below 40°C; additional cooling or ventilation is required if necessary
- Use only copper conductors for wiring; wire cross-section per IEC 60204 standard
- Connect to a grounded three-phase industrial supply network (TN system or TT system with grounded neutral)
- Symmetrical rated current of the supply network must not exceed 42 kA
- If power supply voltage asymmetry exceeds 3%, a line reactor must be used
- Periodic overvoltage between phases and drive housing must not exceed 1000V peak
- Voltage spikes between phases (less than 50 μs) must not exceed 1000V
- Voltage spikes between phase and housing (less than 50 μs) must not exceed 2000V
Usage Notes:
- The “FN3” suffix indicates a specific fieldbus option; verify the fieldbus protocol matches the host controller
- Use the MMC card to back up parameters before performing firmware updates
- The STO function is standard and must be properly wired for safety compliance
- Auto-tuning should be performed after initial motor connection to optimize loop gains
- The drive supports both rotary and linear motors; ensure the correct motor type is selected in configuration
