Table 26.
The POW_SR bits set the slew rate value of the power bridge output:
Table 27.
1. See SRout_r and SRout_f parameters in
The TQREG bit sets if the torque regulation (see
voltage (external) or the TVAL_HOLD, TVAL_ACC, TVAL_DEC and TVAL_RUN registers
(internal):
Table 28.
The TSW parameter is used by the current control system and it sets the target switching
period.
Table 29.
Any attempt to write the CONFIG register when the motor is running causes the command
to be ignored and the NOTPERF_CMD flag to rise (see
