ONFIGURATIONS
It is necessary to set to 1 Motor type in order to control DC motor. Motor type can be set to all the
others value in order to control a brushless motor but is advisable to set the variable to 10 as
described in DS402 specification.
Motor rated torque and Motor rated current must be set in function of the motor nameplate data.
Through ENCODER TYPE it is possible to choice between Hall encoder (ENCODER TYPE equal to 2)
and incremental encoder with Hall (ENCODER TYPE equal to 0).
Motors with Hall encoder, in order to work properly with AZ3s, must be phased with the Hall states
positioned relative to the U alignment as described in the image below (Hall states are in U, V, W
sequence).
