4. OPERATION

(b) Continuous move command (MOVA MOVIA)

POINT

"MOV" cannot be used with "MOVIA", and "MOVI" cannot be used with
"MOVA".

The "MOVA" command is a continuous move command for the "MOV" command. After execution of
the movement by the "MOV" command, the movement of the "MOVA" command can be executed
continuously without a stop.
The speed changing point of the "MOVA" command is the deceleration starting position of the
operation performed by the preceding "MOV" and "MOVA" commands.
The acceleration/deceleration time constant of the "MOVA" command is the value at execution of
the preceding "MOV" command.
The "MOVIA" command is a continuous move command for the "MOVI" command. After execution
of the movement by the "MOVI" command, the movement of the "MOVIA" command can be
executed continuously without a stop.
The speed changing point of the "MOVIA" command is the deceleration starting position of the
operation performed by the preceding "MOVI" and "MOVIA" commands.
The acceleration/deceleration time constant of the "MOVIA" command is the value at execution of
the preceding "MOVI" command.

Use of an S-pattern time constant allows sudden operation to be eased at the time of acceleration
and deceleration.
