V5QSG-02
1 of 6
This quick start guide in meant to allow the reader a basic understanding of the function detailed
and to outline the most basic requirements for sample operation of the function.
Before attempting actual machine operation or to find more advanced information, please refer to
the V500 Instruction Manual and the appropriate option instruction manual if so applicable.
1. Concept
The V500 series inverter is capable of performing conditional position feed function-using contact
inputs. Movement enable is determined by status of Servo On (LX). Movement direction is
determined by Start Forward (STF) or Start Reverse (STR) selection. Movement speed is
determined by parameter settings. Movement length is determined by parameter settings.
2. Valid Inverter Modes
This function is valid for only the following modes:
•
External
(EXT)
•
Network
(NET)
•
Combined (Pr.79 = 4)

4. Data Parameter Setting Details
Set position command value using position feed amount parameters as a set of two.
Formula: resolution of encoder x number of motor rotations x 4 = position feed amount
Example:
To rotate motor 100 revolutions using 1024 ppr encoder and terminal RH
1024 x 100 x 4 =
409600
(feed amount)
Pr. 466 (upper 4 digits) =
0040
Pr. 465 (lower 4 digits) =
9600
Example:
To rotate motor 1.25 revolutions using 1024 ppr encoder and terminal RM
1024 x 1.25 x 4 =
5120
(feed amount)
Pr. 468 (upper 4 digits) =
0
Pr. 467 (lower 4 digits) =
5120
