So that no problems arise during mid-program startup, or when horizontal/
vertical spindles are in use, gear shifting should be realized for the spindle via
various sets of parameters.
A changing nominal speed value ramp can be output to shift gears by
alternately setting and resetting M4009 and M4010. This can be realized by
interrogating the timers in the PLC program. This function also works if you
have used M4008 to disable the speed output for the spindle:
In MP3240.2, define the nominal speed value that is output with M4009/
M4010 to the spindle motor.
MP3030 Behavior of the spindle
Input: Bit 1 – Zero spindle speed when shifting to another gear range
0: Reduce speed to 0
1: Do not reduce speed to 0
MP3240.2 Analog spindle: Spindle jog voltage for gear shifting
(M4009/M4010)
Input: 0 to 9.999 [V]
MP3240.2 Digital spindle: Motor speed for gear shifting (M4009/
M4010)
Input: 0 to 9.999 [1000 min
