1、Determining the value to be set for $CURR_MON with external axesBackground:If the value of $CURR_MON is set too low, acknowledgement message 1241 is generated:ixt monitoring, current limit of the motor cable E1 after 60 s exceeded 100%In such a case, the current r.m.s. value must be calculated from
