11.4 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%):
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.
