Troubleshooting
If gearing is not working properly, the problem could be in one of two places: 1) getting the master
signal into the drive and 2) calculating the geared command. Most problems are getting the master
signal into the drive. The internal variable DF3MASTER allows you to monitor the gearing master
signal. Using the terminal screen in “DRIVE.EXE,” type “M DF3MASTER;” this prints the
gearing master signal in hex. If the value changes by more than 1 count, then a master signal is
being received.
Not changing or changing
by one count
Check encoder
signal emulator,
i.e. master signal
Check
GEARMODE
Changing by more
than 1 count
Gearing works?
yes
END
no
Check FPGA = 1
(if using X5 as
master signal)
Check
ENCMODE
M DF3MASTER
Ensure gear ratio is
> 0
Ensure drive is
enabled
