Square of peak motor current

You will find a complete status list on Page207.

Reference value: 80 000A2

The maximum peak current of a motor phase is continually determined once COMPAX is switched on and this is stored as status S13 or S14 using P233/234=56.

This display is generated as long as the motor is powered. The value is reset when COMPAX is switched off (after "OFF").

Obtaining the peak motor current using S13 (P233=56) as an example:

Imax = S13 * 80000A2

Use the effective value

Ieff = Imax

2

to calculate the peak load within the motor cycle.

If this value rises to 1.5 times the peak current of the system, error E41 is triggered. You will find more detailed explanations on the limiting characteristics of COMPAX on Page 222.
