NORDAC PRO (SK 500P series) – Manual with installation instructions 5 Parameter WARNING Unexpected movement Connection of the supply voltage may directly or indirectly set the device into motion. This can cause unexpected movement of the drive and the attached machine, which may result in serious or fatal injuries and/or material damage.
Page 79 5 Parameter WARNING Unexpected movement due to overload In case of overload of the drive, there is a risk that the motor will “break down” (sudden loss of torque). An overload may be caused e.g. by inadequate dimensioning of the drive unit or by the occurrence of sudden peak loads.

NORDAC PRO (SK 500P series) – Manual with installation instructions The same limit values apply to both standards. However, the standards differ with regard to an application that is extended in the product standard.

NORDAC PRO (SK 500P series) – Manual with installation instructions 8.4.2 Reduced overcurrent due to time The possible overload capacity changes depending on the duration of an overload. Several values are cited in this table. If one of these limiting values is reached, the frequency inverter must have sufficient time (with low utilisation or without load) in order to regenerate itself.

If necessary, provide protection against falling (e.g. for lifting equipment) or equivalent protective measures. NORD frequency inverters have a low power consumption and are therefore highly efficient. In addition, with the aid of "Automatic flux optimisation" (Parameter (P219)) the inverter provides a possibility for increasing the overall efficiency of the drive in certain applications (in particular applications with partial load).
