Driver NUM GEC MK2S

So I tried to adjust my drivers,

I started to set zero offset, I didn't feed the analog and I set the motor to slip as little as possible.

I powered the analog at 10V, set reference input at 10V and set tacho input at 1600 rpm. so 10V-1600 rpm.

as for the de I and epsilon settings, I have leave as it was either set to full.

as for speed stability, nothing happened when I moved it, except when I started to set it to full, a buzz appeared but nothing visible on the motor rotation.

My setup is as follows:

Motor 1600 rpm  - 10V anlog
pulley ratio: 14/28 = 0.5
leadscreaw pitch = 10 mm/turn
Encoder : 2500 PPR

 

So,

My INI file should be

MIN_LIMIT = 0
MAX_LIMIT = 1000
MAX_VELOCITY = 133.3 (1600 tr/min * 0.5 (14/28) *10) 8000 mm/min 133.3 mm/s
MAX_ACCELERATION = 300

[JOINT_1]
CARD = 0
TAB = 1
AXIS = Z
MIN_LIMIT = 0
MAX_LIMIT = 1000
MAX_VELOCITY = 133.333
MAX_ACCELERATION = 300
TYPE = LINEAR
SCALE = ????????????????????
ANALOG_SCALE_MAX = 10
ANALOG_MIN_LIMIT = -10
ANALOG_MAX_LIMIT = 10
ENCODER_SCALE = 1000      (2500*4)/10
FERROR =  0.005
MIN_FERROR =  0.0025
DEADBAND = 0
P = 1
I = 0
D = 0
FF0 = 0
FF1 = 0
FF2 = 0
BIAS = 0
MAX_OUTPUT = 0
MAX_ERROR = 0.0127
HOME = 10
HOME_OFFSET = 0
HOME_SEARCH_VEL = 5
HOME_LATCH_VEL = 0.5
HOME_FINAL_VEL = 20
HOME_SEQUENCE = 1
HOME_USE_INDEX = True


WHAT should i put SCALE Value AND MAX OUTPUT ?

Suggested changes in Blue:

MIN_LIMIT = 0
MAX_LIMIT = 1000
MAX_VELOCITY = 120
MAX_ACCELERATION = 300

SCALE =  133 
(or possibly -133) to get the feedback direction correct
 

ANALOG_SCALE_MAX = 133
ANALOG_MIN_LIMIT = -133
ANALOG_MAX_LIMIT = 133

Is correct ?

Those seem to be unused so irrelevant
 

Thanks, the axes move perfectly!

I've just set the PID parameters for my axes.
i'd like to know if bounces are ok or should i have as few as possible?
because the procedure is very well written, except that it doesn't specify what scale to stop at.
At 50 mv/div, are bounces negligible?

the images are relative to my X axis (with the turret), which is why there are more bounces when drawing. Im actualy at P=125 and F1=1
