Time T0 to T3 determines the motor speed, while the difference of phase direction
between phase signals DMPH1-P and DMPH2-P (RMPH1-P and RMHPH2-P)
determines the rotation direction, DMON1-N signals control a motor coil current.
According to the polarity of the phase signal, the coil current flow as follows:
1) +38V

The voltage drop across the reisistor is input to comparator, where it is compared
with a reference voltage. If an overcurrent flow occurs, a limiter operates to maintain
it within a certain fixed amount of current.
