The Feed rate is in tools per minute.

60 seconds in a minute / Feedrate: tools per minute x 8 tools in the tool changer = Time in seconds for one full revolution


Acceleration rate of the stepper motor in tools per sec ^2


The number of steps required to move between tool position


Once the required tool position has been reached this is the number steps are required to move pass the tool lock position to ensure that when the tool changer reverses it will lock into position.


This is the number of steps required to reverse and lock the tool into position





Tool changer logic


After all the axis of the machine have been homed as per the homing sequence, the tool changer logic will start rotating the stepper motor for the turret till a home (Tool 0) signal is received.


If a valid tool home signal is not received in one full revolution, the controller will display an alarm on the screen.


On a tool change request, MASSO will start rotating the turret stepper motor till the desired tool has been loaded into position.
