Control details

In the MC_GearIn, RatioNumerator, RatioDenominator, MasterValueSource, Acceleration, Deceleration, Jerk, and
BufferMode are set and the gear operation starts.
To stop the operation, execute the MC_Stop.
After executing the instruction, Slave continues acceleration/deceleration until reaching the target velocity which is a value
converted the speed of Master by the gear ratio. After reaching the target velocity, InGear turns TRUE, and Slave is controlled
with the speed converted the speed of Master by gear ratio.
During acceleration/deceleration During gear synchronization
