Hello guy,

1801.0 to 0
after reboot the machine show me Z AXIS DETECT ERROR

Just a quick update
i have success to set parameter for the X and Y axis after change alot of parameter according to parameter manual
but no way to find the correct DMR or flexible feed gear for the Z axis which is running a semi-closed loop
Z pulse coder: A860-0310-T115 25000P
ballscrew pitch 10mm (mounted directly to the motor)
param:
1891=10000 (4*Number of pulse coder pulses/10) according to AC Servo Amplifier Maintenance GFZ-65005E07 page 1-16

i also tried a N/M of 2/5, 1/10, look like it have to be somewhere in middle but i dont know the exact value

with CMR =2 and the N/M 10/25 or 2/5 should match your set up

thank for your reply
i have the same result by using equation from the manual but the Z only move about 0.035mm with handle multiplier x100 (0.1mm)

with CMR =2 and the N/M 10/25 or 2/5 should match your set up
