Menu 4: Torque and current control

MOTOR1_CURRENT_LIMIT_MAX is used as the maximum for some parameters such as the user current limits. The current maximum current limit
is defined as follows (with a maximum of 1000 %):
CURRENT_LIMIT_MAX =
Where:
Motor rated current is given by Pr 5.07 {SE07, 0.28}
(MOTOR2_CURRENT_LIMIT_MAX is calculated from the motor map 2 parameters). The maximum current is 1.5 x drive rating.
