6-6 Pulse Train Position Control Mode
• To use this function, set the 1st Control Method (A044) to 05 (Sensor vector control) and the V2
Control Mode Selection (P012) to 01 (Pulse train position control).
• Select the input mode for the pulse train position command in the Pulse Train Input Selection (P013).
• Set the positioning completion signal that determines the completion of position control.
Set the Multi-function Output P1 to P5 Selection (C021 to C025) or the Multi-function Relay Output
(MA, MB) Function Selection (C026) to 23 (POK: Position ready).
The position completion signal will be output when the current position reaches the target position
range set in the Positioning Completion Range Setting (P017). In the Positioning Completion Delay
Time Setting (P018), set the time until the signal is stabilized depending on your application.
6-6-1 Pulse Train Position Control Mode Settings
Under sensor vector control, select the heavy load mode (b049 = 00).
