TOMATECH AUTOMATION
Note 2: When the rapid override is F0, the min. rapid traverse rate is set by bit parameter No.032.
8.1.6 Spindle speed adjustment
While the spindle speed is controlled by the analog voltage output in Auto mode, it can be
adjusted by spindle override.
Press , to adjust the spindle override for the spindle speed, it can realize 8-level
real-time override adjustment between 50％～120％.

Ⅱ Operation
Note : The actual output analog voltage = analog voltage by parameter × spindle override.
8.2 Running State
8.2.1 Single block execution
When a program is executed firstly, the system selects the single block run mode to avoid
the
program error to cause the unexpected.
Press to select the single block run function in Auto mode; in single block mode, after the
current block is executed, the CNC stops run; press to execute the next block. Such
repetition
is executed till the program is done.
Note 1: The single block stops at the mid point of G28 code.
Note 2: For the single block state in the execution of canned cycle codes G90, G92, G94, G70～
G76, refer to
the 1st part PROGRAMMING.
Note 3: While the subprogram calling (M98＿ ), or subprogram calling return (M99)is being
executed, the
single block is inactive. But it is active except for N, O, P addresses in the block that contains M98
or
M99 code.
8.2.2 Dry run
Before the program is to be executed automatically, in order to avoid the programming
errors, it
may select the Dry run mode to check the program.
In Auto mode, press to enter the dry run state; in Dry run state, the machine feed and
miscellaneous functions are both active (as machine lock, MST lock are both OFF), that
means the
dry run switch has nothing to do with the machine feeding, MST functions, so the feedrate
by program
is inactive and the CNC system runs at the speed described in the following table:
