5.4.4 Feedback and Commutation Parameters
Different sources for the feedback of motor position to the controller are available. The following table lists these
options. In the case where no encoder is used (i.e. comfbk = 1), then the encoder parameters may not need to be
set. The resolver reference amplitude is in units of 32768/2V, Typically the default value for the resolver’s
reference amplitude is used. The number of resolver poles is required regardless of the feedback source. The
values for encoder set-up are listed in the encoder section, and are summarised in the table below: -

5.4.5 Bus Parameters
The default value for the bus over-voltage limit is 800, with defaults of 760 and 780 for the regen. off and on limit
respectively.

5.4.6 Motor Thermal Parameters
The coefficients that characterize the NTC of the motor, must be set for each motor. The temperature and span at
which the current is foldback as a function of motor temperature, can also be set, along with the maximum
temperature allowed for the motor. Thermal foldback is only possible where a NTC is present in the motor.
The motor thermal limiting is enabled by default, so the user should not modify the current limit mask setting.
