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."
