VM_USER_CURRENT[MAX] = User Current Maximum Scaling (04.024)
VM_USER_CURRENT[MIN] = -VM_USER_CURRENT[MAX]
User Current Maximum Scaling (04.024) defines the variable maximum/minimums VM_USER_CURRENT which is
applied to Percentage Load (04.020) and Torque Reference (04.008). This is useful when routing these parameters to
Definition an analog output as it allows the full scale output value to be defined by the user. This maximum is subject to a limit of
MOTOR1_CURRENT_LIMIT or MOTOR2_CURRENT_LIMIT depending on which motor map is currently active.
The maximum value (VM_TORQUE_CURRENT_UNIPOLAR [MAX]) varies between drive sizes with default
parameters loaded. For some drive sizes the default value may be reduced below the value given by the parameter
range limiting.
