6.6.2 Spindle-specific MD bits (spindle bits)
Bit 2 Bit 2=1 Must be set when a function calling for a spindle encoder is required, e.g.
•
G33/34/35
(Thread cutting)
•
G 95
(Feedrate per revolution)
•
G 96
(Constant cutting speed)
•
G 97
(Freeze spindle speed)
•
M 19
(Oriented spindle stop)
The encoder is allocated in MD 400*, which also activates the hardware
monitor for the measuring circuits. If the M19 option is invoked, bit 2 must be
set to 1 (also see Section entitled ”Axis (Analog) and Spindle Installation”).
Bit 1 Bit 1=1 The sign of the spindle encoder pulses is inverted every time this bit changes
its status.
