Deceleration Time T
DEC
1. T
DEC
is the time required from maximum speed V
MAX
(D1822, D1902, D1982, D2062) to bias speed V
BIAS
(D1824
D1904, D1996, D2064).
2. If the value is smaller than 10ms, the output will be set as 10ms; if the value is biggler than 32767 ms, the output
will be set as 32,767 ms.
3. If you need a complete S curve, please set the operation speed (
V) as maximum speed V
MAX
.

Target Position (I) (P(I))
1. Range: -2,147,483,648 ~ +2,147,483,647; the unit is set by b0 and b1 of D1816 (D1896, D1976).
2. Attribute of target position P(I):
♦ Absolute coordinate: b12 of D1816 (D1896, D1976, D2056) = 0
Absolute coordinate is the coordinate starting from “0.” When the target position P(I) > current position
(D1848, D1928, D2008, D2088), the motor will conduct forward running. When the target position P(I) <
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(I) varies according to the settings of b2 and b3 in D1816 (D1896, D1976,
D2056).

Operation Speed (I) (V(I))
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.
3. Setup range limitation: V
MAX
> V(I) > V
BIAS
.
4. When b4 of D1846 (D1926, D2006, D2086) = 1, which enables variable speed operation, the operation speed V(I)
can be modified during operation. When the sign of V(I) is “+”, the motor will conduct forward running; when the
sign of V(I) is “-“, the motor will conduct reverse running.
