Main and second spindle
7.9.1 Spindle types
The setting of spindle parameter SPDLTYPE (P0) allows the following possibilities:
SPDLTYPE = 0 Spindle analog command output..
SPDLTYPE = 1, 2-digit BCD coded spindle command output S.
SPDLTYPE = 2, 8-digit BCD coded spindle command output S.
When using BCD (2 or 8 digits) coded command output, the spindle will operate in open loop and
it will be controlled by means of functions M3, M4 and M5.
When using analog command output, the spindle can operate:
• In open loop, controlled by means of functions M3, M4 and M5.
• In closed loop, by means of function M19. This requires an encoder mounted on the spindle and
spindle parameter NPULSES (P13) must be set to a value other than "0".
• Controlled via PLC. With this feature, the PLC may take control of the spindle for a certain period
of time.
A typical application of this feature is the control of the spindle oscillation during the spindle gear
change.
Regardless of the type of spindle command being used, the CNC admits up to 4 spindle gears.
The spindle gear change may be made either manually or automatically by the CNC.
To change spindle gears, functions M41, M42, M43 and M44 are used to let the PLC know which
one is to be selected.
