      Select EMCOturn 120 from the list

There are no configurable settings for this tool changer.

Tool Changer Logic

After all machine axes are homed according to the homing sequence, the tool changer reads the encoder data from the turret to determine the current tool position.

If a valid tool number is received, the current tool number is updated on the controller. If the signal is invalid, an error message is displayed indicating that the turret signals are incorrect.

On a tool change request, MASSO sets Tool Changer - Output 1 HIGH to rotate the tool changer clockwise until the requested tool is in position. Once the tool is in position, Tool Changer - Output 1 goes LOW and Tool Changer - Output 2 goes HIGH for 1000 ms to rotate the tool changer counterclockwise and lock the tool in position.

Syntax

The following syntax is used for Tool Changer inputs and outputs:

• “Tool Changer - Output 1” means Tool Changer - 1 and it is an output
• “Tool Changer - Input 1” means Tool Changer - 1 and it is an input

Note: Any tool changer input or output can be assigned to any Input or Output on MASSO. The tool changer number does not refer to a physical input or output port.

Input Signals

Wire the sensor inputs and assign them in MASSO as follows:

• Tool Changer - Input 1 for Turret signal-1
• Tool Changer - Input 2 for Turret signal-2
• Tool Changer - Input 3 for Turret signal-3
• Tool Changer - Input 4 for Turret signal-4

Output Signals

Wire the turret control signals to any free outputs on MASSO as follows:

• Tool Changer - Output 1 for motor clockwise rotation
• Tool Changer - Output 2 for motor counterclockwise rotation

Input Signal Sequence Chart

The table below shows the signal sequence based on EMCO documentation. Ensure your turret outputs match this sequence for correct operation with MASSO.
