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) deter-
mines 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:
+38V ∅ SW ∅ motor coil ∅ SW ∅ resistor ∅ earth, or,
1)
+38V ∅ SW ∅ motor coil ∅ SW ∅ resistor ∅ earth
2)
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.
