8 Command Reference
VC[±]
Move at constant velocity
This command is used to move the motor at a constant velocity in the direction specified, without
any target position. If the direction is not specified, the motor moves in the positive direction.
PMCprimo accelerates the motor at the defined acceleration until it reaches the velocity set by the
SV command (see page 38). If then controls the motor at constant velocity, until it is told to stop.
While in constant velocity mode, PMCprimo gives the ‘V’ velocity control prompt character.
Velocity control mode can only be entered from position control mode, and not directly from the
motor off state.

This command line set the acceleration to 1000
incr./sec.2, the velocity to 2000 incr./sec. and
accelerates channel 1 at the defined acceleration until
it reaches the velocity set by “SV” and moves with
constant speed in positive direction.
Figure 6: Constant velocity move
The velocity values “SV” and “SS” can also change during “VC”.
