Controller got a malfunction and didn't work .We change the controller
with the same type but which was 7 axis hardware config(7 KSD), the robot
body doesn't have external axis. We reconfig the mada data and do
calibration 6 axis with EMT. Robot plays well,no alarm or any error
messages, but we check the robot carefully,the problem appeared.
1 . We found its repeatability overstep +/- 0.2mm,even 2or3 mm.
2 . The AXIS 1 brake didn't work well. Manually joggle the AXIS 1 (No
tools on Robot even tool changer )in the T1 model and 20% speed,it is very
vety slow actually,release the Deadman the robot would shaked evidently!
Only one more KSD in the controller different,is that "KSD" make all
above two problems ? do we need remove the KSD? We have no idea now~..
Any help will be appreciated~!
P.S . Controller Type VKRC2
