5. HOW TO USE THE PROGRAM
5 - 12
3) Program example 3
Using the S-pattern acceleration/deceleration time constants reduces abrupt movements at
acceleration or deceleration. When the "STD" command is used, [Pr. PC03 S-pattern
acceleration/deceleration time constant] does not function.
Command Description

(b) Continuous travel commands (MOVA/MOVIA)
POINT
A combination of "MOV" and "MOVIA" commands, and a combination of "MOVI"
and "MOVA" commands are not available.
The "MOVA" command is a continuous travel command for the "MOV" command. After the travel
with the "MOV" command is executed, the travel with "MOVA" command will be executed
continuously without a stop.
The speed specified by the "MOVA command" is enabled from the deceleration start point of the
preceding "MOV" or "MOVA" command.
The acceleration/deceleration time constants for the preceding "MOV" command is also applied to
those for the "MOVA" command.
The "MOVIA" command is a continuous travel command for the "MOVI" command. After the travel
with the "MOVI" command is executed, the travel with "MOVIA" command will be executed
continuously without a stop.
The speed specified by the "MOVIA command" is enabled from the deceleration start point of the
preceding "MOVI" or "MOVIA" command.
