6.3.5 FB 424 MC_Phasing - Change phase shift between master and
slave axes
Valid for firmware version V3.1.x of the integrated technology
Purpose
• The "MC_Phasing" technology function sets a phase shift between the leading
axis position and the following axis. This does not actually influence the
position of the leading axis.
• The effect on the following axis in cam synchronism is the same as a horizontal
cam shift.
• The phase can be referenced relative or absolute.
• The function can be started when the axis is at a standstill and also when it is
moving.
• Use the dynamic parameters Velocity, Jerk, Acceleration, Deceleration to
define the dynamic response during axis movement.
Applicable to
• Synchronization axes in camming or gearing mode
Requirements
• An MC_Stop command is not busy at the following axis
• The axis must be configured as slave for operation in an existing gearing or
camming compound.
