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 RMPH2-P) determines the rotation
direction. DMON1-N and RMON-N signals control a motor coil current. According to the
polarity of the phase signal, the coil current flow as follows:
1) +38V → SW → motor coil → SW → resistor → earth, or,
2) +38V → SW → motor coil → SW → resistor → earth
The voltage drop across the resistor 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.
