given as a percentage of the reference current). Note that values that are too high
will cause Error 0x73A6 to be triggered.
Typically the motor moves by 4% of the pitch length or, with rotary direct drives 4%
of 360°/number of pole pairs - maximum 50%.
Note the following conditions for automatic commutation
! The linear motor must not be at the end limits for automatic commutation.
! Actively working load torques are not permitted during automatic commutation.
! Rubbing caused by friction deteriorates the effect of automatic commutation.
! With the exception of missing commutation information, the controller/motor
combination is configured and ready for operation (parameters correctly assigned
for the linear motor/drive). The transmitter and the direction of the field of rotation
in effect must match.
! The auto-commutating function must be adapted to fit the mechanics if necessary
during commissioning.
