31 POSITIONING INSTRUCTION
31.1 Common Items
(2) Bias speed < Command speed < Start speed: Start speed = Command speed
(3) Start speed < Bias speed, or Command speed < Bias speed: Start speed = Bias speed
For the PLSV/DPLSV instruction and table operation instruction (control method: [4: Variable Speed Operation] or [5: Table
Transition Variable Speed Operation]), the following equations are used instead of those above:
(4) Acceleration time = 0: Start speed = Command speed
(5) Acceleration time  0: Start speed = Bias speed
Acceleration time (7 ms)
Maximum speed (100 pps)

Bias speed (5 pps)
Maximum speed: 100 pps
Bias speed: 5 pps
Command speed: 10 pps
Acceleration time: 7 ms
Start speed =
100 pps - 5 pps
7 ms
= 13.57… (pps)
In the case of Bias speed (5 pps) < Command speed (10 pps) < Start speed (Approx. 13.6 pps)
Start speed is the same as
(1), the speed is increased
from Bias speed to
Command speed.

(100 pps)
Maximum speed: 100 pps
Bias speed: 20 pps
Command speed: 10 pps
Acceleration time: 10 ms
Start speed =
100 pps - 20 pps
10 ms
= 8 (pps)
In the case of Command speed (10 pps) < Bias speed (20 pps)
In the case of Command
speed < Bias speed, Bias
speed is Command speed.
