Positioning speed.
The positioning speed of the spindle Sn is defined using the command
Sn.POS as follows:
Sn.POS Positioning speed of spindle Sn.
The positioning speed is given in rpm.
If no positioning speed is programmed, the CNC assumes the one set
by machine parameter REFEED1 as the positioning speed.
Gear change (M41-M44)
M41-M44 Spindle gear change.
The spindle gear (range) desired for the programmed speed is
selected with functions M41, M42, M43 and M44. The CNC may have
up to 4 different spindle gears.
These functions may be defined together with the programmed
spindles or in a separate block. If the block where they are
programmed does not mention any spindle, they will be applied to the
master spindle of the channel.
When using Sercos axes, functions M41-M44 also involve changing
the drive's velocity gear.
