When b-003 = 1, set frequency by terminal state combination which is selected
by E-019, E-020
、
E-021. There are 8 state combination, respectively corresponds
to 1~8 steps speed. (As shown in the following table, 1 represents short-circuiting
between corresponding terminal and COM, 0 represents disconnection between
corresponding term
inal and COM.

When set b-003 as 2 or 3, No.1~ 4 step speed automatic cycle operation (2 is
single cycle, 3 is repeat cycle). Accel /decel time of each step speed is determined
by E-029. When b-003 is not 0 and b-001=5, direction of multi-step speed operation
is determined by the value of E-018. Firstly confirm the corresponding binary value
according to direction

of each step speed, as shown in
the follow figure. Then change to decimal system, namely E-018. When b-003 is not
0 and b-001 = 0, operation direction of each step speed is determined by states of SF,
SR terminals, and it is unrelated with E-018.
