Forward running occurs when P(I) is bigger than CP. Reverse running occurs when P(I) is smaller than CP.
♦
The operation speed will be stable after the speed is accelerated from
V
BIAS
to the expected V(I). When it is
approaching the P(I) value set in the register, the positioning will start to decelerate to V
BIAS
and stop. There
are P(I) pulses generated during the positioning.

The registers involved: D1824 (D1904, D1984, D2054) (V

), D1840 (D1920, D2000, D2080) (V(I)), D1822
(D1902, D1982, D2062) (V

), D1838 (D1918, D1998, D2078) (P(I)), D1836 (D1916, D1996, D2076) (T

)
and D1837 (D1917, D1997, D2077) (T

When PWM mode is enabled (Parameter Setting, D1816/D1896/D1976/D2056, b[6] = 1), and the operation
command “Single-speed positioning” is enabled (b[8] = 1), single-speed positioning will be executed on
Y0~Y3 with single-phase pulses.

♦
When b[9] is triggered and START = ON, the single-speed positioning interruption mode will be started. The
single speed insterruption will be triggered to execute target position P(I) when DOG sensor is detected.
♦
Operation direction: Direction of relative positioning is determined by the sign bit of the value for P(I) (set in
D1838, D1918, D1998). Direction of absolute positioning is determined by current position (CP). Forward
running occurs when P(I) is bigger than CP. Reverse running occurs when P(I) is smaller than CP.
♦
The operation speed will be stable after the speed is accelerated from
V
BIAS
to the expected V(I). When
DOG sensor is detected, the single speed insterruption will be triggered to send out pulses set in P(I)
register. Also, when it is approaching the P(I) value set in the register, the positioning will start to decelerate
to V
BIAS
and stop.
