2 1 0
1 = Ready to start
1 = Ready to operate
1 = Operation Enabled
1 = Drive fault present
0 = OFF2 (Coast stop command present)
0 = OFF3 (Quick stop command present)
1 = Switch-on inhibit
1 = Drive warning present
1 = Not used (always 1)
1 = Serial operation allowed
0 = Serial operation blocked -
local operation only
1 = Frequency reached
