Overload durations D.7T
D.7 Overload durations
For the possible pulse frequencies there are three time constants (see table) in the following parameters:
• P0014 for 4kHz
• P0015 for 8kHz
• P0034 for 16kHz
If the thermal characteristic limit is reached it is automatically limited to the nominal current.
Frequency-dependent nominal currents: The nominal currents for the according pulse frequencies are in:
• P0010 for 4kHz
• P0012 for 8kHz
• P0032 for 16kHz
In the d iag ram the characteristic limits in dependance with the preloading are shown.
