i950

The intelligent i950 cabinet servo inverter can be easily integrated into modular machine solutions on the basis of prepared technology applications - parameterization instead of programming.
The same architecture, the same engineering and the use of the same application software, based on decades of application experience, dissolve the boundaries between centralized and decentralized motion control. Our FAST Application Software Toolbox becomes universally usable. If required, the pre-designed software modules can be very easily customized and extended.
In addition, the i950 cabinet servo inverter serves as a power extension of the i750 cabinet servo inverter in the Lenze automation system in the range from 22 to 110 kW.
The requirements of the Ecodesign Directive, Standard EN IEC 61800-9-2, are met.

Fault ID: 0011
Hex: 0011
Description: Short circuit of motor cable
Keypad display: OC1
Cause Remedy Severity/response

Short circuit

Excessive capacitive charging
current in the motor cable.
  • Search for cause of short circuit.

  • Check motor cable.

    Use motor cable which is shorter
    or of lower capacitance.
