■ ■ ■ ■ ■ VEL
The velocity for the next absolute and relative
positioning procedures and the maximum allowed
velocity for synchronizing procedures is determined
with the VEL command.
The value remains valid until a new velocity is set
via another VEL command. The new velocity value
will be set in reference to the parameters VELMAX
(1) and VELRES (22). If the velocity value equals the
V V V V V elocit elocity resolution elocit elocit y resolution y resolution, then the rpm value set in y resolution
elocit y resolution
Maximum velocit Maximum velocit Maximum velocit Maximum velocity y y y y VELMAX (1) will be used. Maximum velocit
Note: Slave velocity in synchronizing mode is also
limited by the VEL command.
Summary
Set velocity for relative and absolute motion as well
as the maximum allowed velocity for synchronizing
Syntax
VEL v
Parameter
v = scaled velocity value
NB!
If no velocity has been set prior to a positio-
ning or synchronizing command, then the
value of parameter DFLTVEL (33) will be used.
If the velocity needs to be altered during positioning,
it is possible in the NOWAIT ON mode, when the
VEL command is followed by another POSA com-
mand targeting to the desired position.
The maximum speed allowed can be changed at
any time with the command VEL, if a SYNCV,
SYNCP or SYNCM follows the VEL command.

■ ■ ■ ■ ■ WAITAX
The WAITAX command has been designated for
use with an active NOWAIT mode. By use of this
command in NOWAIT ON condition, it is possible
to wait for further program processing after a posi-
tioning command, until the axis has achieved its
set position.
Summary
Wait till target position is achieved
