6.2.10 FB 414 MC_MoveVelocity - Moving with speed preset

Valid for firmware version V3.1.x of the integrated technology

Purpose

• The "MC_MoveVelocity" technology function initiates acceleration of the axis to

its preset velocity.

• Use the input parameters Velocity, Jerk, Acceleration, Deceleration to define

the dynamic response during axis movement.

• When a velocity-override function is active, allowances are made for this

override in the calculation of the final velocity (output parameter InVelocity).

make allowances for these characteristics in your user program.

• You can use input parameter PositionControl to set position or velocity control

mode for position-controlled axes.

• At input parameter Mode you can specify whether to trigger an active motion,

to override the current motion or to append the motion.

Applicable to

• Velocity axes

• Positioning axes

• Synchronization axes

Requirements

• The axis is enabled for velocity and position control

• No MC_Stop command busy

• Requirements for appended motions (Mode = 1):

- An MC_CamIn or MC_GearIn has not been started

- No synchronized operation.

- "MC_MoveVelocity" can not be loaded in order to append it to an active

"MC_MoveVelocity."
