i80L svstem, check #3052 for
program and #3062 for third program.
Does 1/0 signal #3002 (#3052, #3072) change
to the list when the jog speed selection
is changed? Are parameters pm2400 to
set
Jog is correct when:
#3078 DO = 1 #3078 = 1 (6th-axis)
#3078 1 (2nd-axis) #3078 = (7th-axis)
#3078 = (3rd-axis) #3078 = 1 (8th-axis)
#3078 = 1 (4th-axis)
#3078 D = (5th-axis)
When O, the axis does not work.
