Spindle speed function S
The rotation instruction of the spindle is specified by the S code, which is modular, i.e. always valid after
the rotation is specified, until another S code changes the modular value.
The maximum value of the S command is limited by the value set by the spindle parameter "Maximum spindle
speed".
There’re two output modes for S command, and the spindle parameter "Spindle mapping axis" has the
following effects:
➢ Spindle mapping axis: Analog spindle
➢ Mode of inverter analog quantity: according to the ratio of S value and spindle parameter “maximum
spindle speed” multiplied by 10V, the analog voltage value that needs to be output is then obtained. S
command needs to execute M03 or M04 to make analog output upon the designation;
➢ Spindle mapping axis: To specify one feed axis in the axis group
It means the current spindle is the AB phase pulse control mode. At this time, the S value is set by the
spindle encoder and then determine the pulse frequency.

Tool function
Machine tool magazine uses random tool selection mode, i.e. two digits T code TXX specifies the tool
No., regardless which tool set it is in; the range of address T is any integral between 1 and 99.
Waring:
Tool meter must be set properly, or else it will damage the machine tool and cause unpredictable results.
