Hi,
Im trying to configure vfd to mesa TB4.
I have connected as follows:
7I76 TB4 VFD
1 SPINDLE- ==> AI1 COMMON GND
2 SPINDLE OUT ==> ANALOG INPUT AI1
3 SPINDLE+ ==> 10V OUT VFD VS (jumper set so it gives +10V)
4
5 SPINDLE ENA- ==> DI1 / setting no 7: - Forward (FWD) running command terminal
6 SPINDLE ENA+ ==> +24V from vfd
7 SPINDLE DIR- ==> DI2 / setting no 8: - Reverse (REV)running command terminal
8 SPINDLE DIR+ ==> +24V from vfd
I can measure 10v between pin 1-3
And when starting spindle from linuxcnc voltages also adjusts according to speed. 10v=24000 rpm etc
But it just doesnt turn.
VFD display readout also adjusts to correct Hz. 24000 = 800 Hz when controlling speed from linuxcnc
VFD manual -

Im guessing im missing some kind of enable.
Spindle INI section:
Code:
[SPINDLE_9]
P = 0
I = 0
D = 0
FF0 = 1
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 0
MAX_OUTPUT = 24000
OUTPUT_SCALE = 24000
OUTPUT_MIN_LIMIT = 3000
OUTPUT_MAX_LIMIT = 24000

Code:
loadrt abs names=abs.spindle
loadrt lowpass names=lowpass.spindle
addf abs.spindle servo-thread
addf lowpass.spindle servo-thread
