During a manual tool change sequence, the door will automatically open to allow the user to change the tool.

The doors do not open during an automatic tool change.

A sounder output is provided to alert the user that the door is about to open or close.

The doors can also be opened and closed using an external button or by using Gcode.

A door sensor input monitors the status of the door and will put the machine into Feed Hold if the door is opened while machining is in progress.

Inputs and Outputs

Outputs

Door Open / Close
 

This output sets HIGH to open the door.

Sounder

This output provides a warning when the door is about to open or close.

• The output goes HIGH for 1 second before the door starts to move
• It then pulses between HIGH and LOW every 0.5 seconds for the next 5 seconds while the door is moving

Depending on the sounder used, it can be driven through a TTL MASSO relay or directly if it is TTL compatible.

MASSO TTL outputs provide logic level signals only, 5V at 5 mA.

Inputs

Door Open / Close Button

An external button can be configured to open and close the door.

• This input acts as a toggle
• A momentary press will open or close the door depending on its current state
• The input is active when it changes to HIGH

Door Status Input

This input monitors whether the door is open or closed.

• When this input goes HIGH, MASSO will put the machine into Feed Hold
• If “Enable Cycle Start in door close” is enabled in the F1 screen under General Settings, the machine will automatically restart when the door closes
• If this option is not enabled, the machine must be restarted manually using Cycle Start

For more information on the Door input, refer to the Door Input documentation.

Manual Tool Change Door Logic

During a manual tool change:

• The spindle moves to the tool change position
• The sounder outputs a continuous tone for 1 second to warn the door is about to open
• The Door Open / Close output goes HIGH to open the door
• The sounder beeps while the door is opening
• The user manually changes the tool
• The user presses the Door Open / Close button to close the door
• The sounder outputs a continuous tone for 1 second to warn the door is about to close
• The Door Open / Close output goes LOW to close the door
• The sounder beeps while the door is closing
• Once the door is closed, the user presses Cycle Start to confirm the tool change is complete
• The Tool Setter Air Blast cleans the tool setter
• The spindle moves to the tool setter to measure the tool if required
• The spindle returns to its previous position and machining continues

Gcode

• M85 sets the Door Open / Close output HIGH to open the door
• M86 sets the Door Open / Close output LOW to close the door
