Set velocity for relative and absolute motion.
VEL v
Command Velocity [RPM]
v = scaled velocity value
The velocity for the next absolute and relative positioning procedure is determined
with the VEL The velocity for the next absolute and relative positioning procedures
and the maximum allowed velocity for synchronizing procedures are 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 32-80 Maximum
Velocity and 32-83 Velocity Resolution . If the velocity value equals the Velocity
Resolution , then the RPM value set in Maximum Velocity will be used.
NOTE: Slave velocity in synchronizing mode is also limited by the VEL command.
NB!:
If no velocity has been set prior to a positioning or synchronizing command, then
the value of par. 32-84 Default Velocity 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 command 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.

Returns if an alarm is active or not.
VLTALARMSTAT
The command VLTALARMSTAT returns if an alarm is active or not. There are two
possible values, 1<<3 or 1<<6 depending if the alarm can be reset or not.
bit 3 = Alarm(s) present
bit 6 = Trip Lock Alarm(s) present
