Synchronous Gear Operation - Panasonic GM1 User Manual

11.4 Synchronous Operation
In the program example, the master axis is controlled by "MC_MoveVelocity" and the slave axis
moves in sync with the master axis.
When the synchronous operation is completed, the "MC_CamIn_0.InSync" flag is set to TRUE.
The "Busy" flag is set to TRUE during execution. While the "Busy" flag is set to TRUE,
"MC_MoveVelocity_0" and "MC_CamIn_0" must be called every cycle. Otherwise, the
operation will terminate with an error.
To separate the slave axis from the master axis and finish the synchronous cam operation, use
the "MC_CamOut" function block. When "MC_CamOut" is called, the synchronous operation is
terminated and the slave axis continues to move at the same velocity as when the synchronous
operation is terminated. Because the operation continues even after the slave axis is separated
from the master axis, you must stop the slave axis with the "MC_Halt" function block or another
function block.

11.4.2 Synchronous Gear operation

This function performs synchronous gear operation.
Synchronous gear operation: Gear control (POU programming)
Synchronous gear operation can be started and finished using the following function blocks.
● MC_GearIn: Specifies the gear ratio of the master axis and slave axis and starts

synchronous gear operation

● MC_GearOut: Separates the slave axis from the master axis and finishes synchronous gear
operation
Because the operation continues even after the slave axis is separated from the master axis,
you must stop the slave axis with the "MC_Halt" function block or another function block.
The following is an ST program example that performs synchronous gear operation with a gear
ratio of 2:1.
