13.7 Spindle control<br />
13-180<br />
The <strong>ShopMill</strong> spindle control has the following special features:<br />
12.01<br />
S MD 35040 $MA_SPIND_ACTIVE_AFTER_RESET, value 1 causes the NCK<br />
not to switched off the spindle at M2 or M30. In contrast, the <strong>ShopMill</strong> PLC<br />
distinguishes between M2 and M30. The spindle is stopped in response to<br />
M30 or RESET, but not M2.<br />
One of the benefits of this functionality is that the spindle can be started at<br />
any time in manual mode (e.g. for scratching).<br />
S The keys “Spindle right”, “Spindle left” and “Spindle stop” triggers the Shop-<br />
Mill -PLC input signals DB82 DBX9.1 “spindle_start”, DB82 DBX9.4 “spindle_right”,<br />
DB82 DBX9.3 “spindle_left” and DB82 DBX9.2 “spindle_stop”.<br />
The <strong>ShopMill</strong> PLC program writes the following interface signals to the<br />
signal data block:<br />
DB3x.DBX30.0 Spindle Stop<br />
DB3x.DBX30.1 Spindle Start CW Rotation<br />
DB3x.DBX30.2 Spindle Start CCW Rotation<br />
The spindle can be started and stopped when the channel is in the Reset<br />
state (DB21.DBX35.7=1) or when the channel status is ”interrupted”<br />
(DB21.DBX35.6=1) and the program status is ”interrupted”<br />
(DB21.DBX35.3=1).<br />
Note<br />
If the spindle must be stopped when the program is running, then interface<br />
signal ”Feed Stop/Spindle Stop” must be set in the user PLC (DB3x.DBX4.3).<br />
The spindle control can be deactivated via interface signal DB82.DBX9.0.<br />
