This command is only valid in DMODE4 (velocity mode) and DMODE6 or 7
(position mode).
In velocity mode (DMODE4), TVEL reports the commanded ±10V value from
the user before any internal limits are checked.
In position mode (DMODE6-7), TVEL reports the internal velocity command
and is limited by DMVLIM.

The TVELA command reports the velocity as derived from the feedback
device. The sign determines the direction of motion.
Rotary Motors—Positive values represent
clockwise motion and negative values represent
counter-clockwise motion (assuming CMDDIR = Ø,
and that you connected the feedback device
according to instructions provided in “Chapter 2
Mechanical Installation” and “Chapter 3 Electrical
Installation”).
