Important: 
You can use this instruction with the following controllers: 
1756-L6 controllers 
1756-L7 controllers 
1756-L7S controllers 
1756-L8 controllers 
1769-L18ERM controllers 
1769-L27ERM controllers 
1769-L30ERM controllers 
1769-L33ERM controllers 
1769-L36ERM controllers 
Use the MCT instruction to start a transform that links two coordinate systems 
together. This is like bi-directional gearing. One way to use the transform is to 
move a non-Cartesian robot to Cartesian positions. 
Important: 
Tags used for the motion control attribute of instructions should only be used once. 
Re-use of the motion control tag in other instructions can cause unintended 
operation. This may result in damage to equipment or personal injury.
