2. Attribute of target position P(II):
♦ Absolute coordinate: b12 of D1816 (D1896, D1976, D2056) = 0
Absolute coordinate is the coordinate starting from “0.” When the target position P(II) > current position
(D1848, D1928, D2008, D2088), the motor will conduct forward running. When the target position P(II) <
current position, the motor will conduct reverse running.
♦ Relative coordinate: b12 of D1816 (D1896, D1976, D2056) = 1
Relative coordinate is the relative displacement moved from current position (D1848, D1928, D2008,
D2088). When the relative coordinate is a positive value, the motor will conduct forward running. When the
relative coordinate is a negative value, the motor will conduct reverse running..
3. The multiplication of position data P(II) varies according to the settings of b2 and b3 in D1816 (D1896, D1976,
D2056).

Operation Speed (II) (V(II))
1. Range: 0 ~ +2,147,483,647; the unit is set by b0 and b1 of D1816 (D1896, D1976, D2056).
2. V(I) should be specified within the valid speed range of motion instructions: 10 ~ 500kPPS. If the value is bigger
than 500k, the output will be set as 500k; if the value is smaller than 10, the output will be set as 10.

Operation Commands
1. b0 of D1846 (D1926, D2006, D2086): STOP
♦ When b0 is rising edge triggered (0→1), the positioning controller decelerate to stop.
♦ The function is the same as the external STOP input signal. The positioning controller will decelerate to stop
in both situations..
2. b1 of D1846 (D1926, D2006, D2086): START
♦ When b1 is rising edge triggered (0→1), the positioning controller will operates according to operation
conmmands set in D1846 (D1926, D2006, D2086).
3. b2 of D1846 (D1926, D2006, D2086): enabling JOG+
♦ b[2] = 1: JOG+ sends out forward pulses (CW)
♦ When PWM mode is enabled (Parameter Setting, D1816/D1896/D1976/D2056, b[6] = 1), and the operation
command “JOG+ operation” is enabled (b[2] = 1), PWM will be executed on Y0~Y3.
4. b3 of D1846 (D1926, D2006, D2086): enabling JOG-
♦ b[3] = 1: JOG- sends out reverse pulses (CCW)
5. b4 of D1846 (D1926, D2006, D2086): variable speed operation
♦ When b[4] = 1 and operation is started (START terminal is ON), DVP-PM will start to send out pulses for
performing variable speed operation on positioning controller.
♦ The operation speed will be stable after the speed is accelerated from
V
BIAS
to the expected V(I). When
