MOVL and MOVC are measured in?

• A. They are expressed as V=Control_point_speed units of cm/min, mm/min, in/min, or mm/sec.
• B. They are measured in degrees
• C. They are measured in percent
• D. They are measured in radians

Answer: (A)

MOVL and MOVC control the tool’s travel along a straight line or a circular arc, so the speed readout is the linear velocity of the end-effector along that path. That velocity is expressed in linear distance per unit time, such as cm/min, mm/min, in/min, or mm/sec. Angular units like degrees or radians would describe rotation, not how fast the tool travels through space, and a percentage isn’t the standard way to specify this linear speed. The speed given is the control point speed, which the controller translates into joint motions to follow the desired path.
