■ Energization mode table


Input Mode A Mode B Mode C	Condition energization mode	1 step angle (degree)	Basic step division
LL H 2EX		1.2	1
LH H	2-3EX	0.6	2
HL H	W2-3EX	0.3	4
HH H	2W2-3EX	0.15	8
HH L	4W2-3EX	0.075	16

When Mode C = "L", 1 step operation is performed for each rising edge and falling edge of the Clock pulse. If the duty ratio of the drive pulse moves out of the adjustment significantly by 50%, operation becomes unstable.

• For the R1 and R2 constants, determine the Vref voltage according to the following equation. Vre(V)= motor current adjustment value(A/phase)x 0.41

Notice that 100 G is recommended for R2 due to the configuration of the internal circuit of the PMM3501.

• Place the GND side of the source by-pass capacitor of Vcd(C1)as close to pins 27 and 28 as possible to reduce noise.
