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:

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.
