10. Spindle Functions
10.1 Spindle Functions (S6-digits Analog)
Function and purpose
When the S6-digits function is added, a 6-digit value (0 to 999999) can be designated after the S
code.
Always select S command binary output when using this function. If the S function is designated in
the same block as a movement command, the commands may be executed in either of the
following two orders. The machine specifications determine which one is applied.
(1) The S function is executed after the movement command.
(2) The S function is executed simultaneously with the movement command.
By assigning a 6-digit number following the S code, these functions enable the appropriate gear
signals, voltages corresponding to the commanded spindle speed (r/min) and start signals to be
output.
If the gear step is changed manually other than when the S command is being executed, the
voltage will be obtained from the set speed at that gear step and the previously commanded speed,
and then will be output.
The analog signal specifications are given below.
(1) Output voltage ............... 0 to 10V
(2) Resolution...................... 1/4096 (2
-12
)
(3) Load conditions ............. 10k
Ω
(4) Output impedance ......... 220
Ω
If the parameters for up to 4 gear stages are set in advance, the gear stage corresponding to the S
command will be selected and the gear signal will be output. The analog voltage is calculated in
accordance with the input gear signal.
(1) Parameters corresponding to individual gears .......Limit rotation speed, maximum rotation
speed, shift rotation speed, tap rotation
speed.
(2) Parameters corresponding to all gears ...................Minimum rotation speed, orientation
rotation speed
10.2 Spindle Functions (S8-digits)
Function and purpose
These functions are assigned with an 8-digit (0 to 99999999) number following the address S, and
one group can be assigned in one block.
The output signal is a 32-bit binary data with sign and start signal. Processing and completion
sequences are required for all S commands.
