6.3.8 FB 440 MC_GearInSuperImposed - Start superimposing gear
synchronism
Valid for firmware version V3.1.x of the integrated technology
Purpose
• The "MC_GearInSuperImposed" technology function starts superimposing
gearing between a leading axis and a following axis.
• You define the dynamic characteristics of slave synchronization at the dynamic
parameters Velocity, Jerk, Acceleration, Deceleration you define the dynamic
characteristics of slave synchronization.
• The gear ratio is defined as the ratio between two integer numbers at the input
parameter (nominator / denominator.)
• Synchronism can be defined relative to the start position (random position
values upon reaching synchronism) or absolute.
• The gear ratio can be changed when the system is in RUN by outputting a new
MC_GearInSuperImposed command. This operation does not require a stop of
the leading or following axis. Transitions are executed according to the
specified acceleration or deceleration values.
• The function can be started when the leading axis is at a standstill, or when it is
in motion.
Applicable to
• Synchronization axes with superimposing synchronization object
Requirements
• The leading axis is configured for operation as external encoder, or as
positioning or synchronization axis.
• The following axis is configured as synchronization axis with superimposing
synchronization object.
• The leading axis is set as available superimposing synchronization object of
the following axis.
• The following axis is enabled for position-controlled operation
• No MC_Stop command is busy at the following axis
