Speed
MD35035 $MA_SPIND_FUNCTION_MASK Bit 4 = 1
When movement starts the speed
is read from setting data:
SD43200 $SA_SPIND_S.
Setpoint speed:
MD35035 $MA_SPIND_FUNCTION_MASK Bit 5 = 1
The content from setting data:
SD43200 $SA_SPIND_S
is used as the setpoint speed.
Constant cutting speed:
MD35035 $MA_SPIND_FUNCTION_MASK Bit 8 = 1
Read from setting data:
SD43202 $SA_SPIND_CONSTCUT_S.
Notes on machine data MD35035 $MA_SPIND_FUNCTION_MASK:
For bit 4 and bit 8, the following also applies:
