7. SPINDLE CONTROL

7.1 Outline of Functions

Spindle speed can be directly controlled by a 6-digit S code command.
When the S analog function specifications are valid, the controller selects an appropriate spindle
speed corresponding to the 6-digit command following the S code and outputs (spindle gear shift
command) it to the machine side (PLC). The controller also outputs S command data (analog
voltage or serial connection data) corresponding to the gear input (spindle gear select input) and
spindle speed specified by the machine side (PLC).

7.1.1 Related Parameters

The PLC can have up to four gear stages.
The table below lists the four gear stages and the corresponding parameters.
