Material Handling

Information Required for Model Selection

  1. Motor nameplate, motor type, rated voltage, power and current
  2. Crane or hoist type, rated lifting load and duty cycle
  3. Required control mode and encoder type, when closed-loop control is used
  4. Mechanical brake arrangement and required braking frequency
  5. Quantity, destination country or port and required optional communication

Installation Notes

  • Install indoors, away from direct sunlight, dust, corrosive gas, combustible gas, oil mist, vapor, dripping water and salt.
  • Use shielded encoder cable and ensure reliable grounding.
  • Do not install a capacitor or surge suppressor on the AC drive output.
  • Do not start or stop the drive by repeatedly switching the input contactor.
  • Installation, wiring and commissioning must be completed by qualified personnel in accordance with the manual and local requirements.

Frequently Asked Questions

What is the S700 power range?

The S700 manual lists three-phase 380V models from 0.75kW to 400kW.

Does the S700 support closed-loop vector control?

Yes. It supports CLVC, SFVC and V/F control. CLVC requires a compatible encoder and the corresponding feedback interface.

What is the maximum startup torque?

The S700 provides 200% startup torque at 0.0Hz under CLVC and 200% at 0.5Hz under SFVC.

Can it control a mechanical crane brake?

Yes. The S700 provides crane-specific brake time-sequence control. The external brake circuit and braking components must be selected for the actual load and duty cycle.

Are anti-sway and synchronized lifting standard?

No. Offset correction, synchronization, positioning, anti-swaying and grabbing require the optional crane process card and project configuration.
