Warnings
Faults which occur, but which do not cause a switch-off of the amplifier output stage (BTB/RTO contact remains closed), are indicated in the LED display on the front panel by a coded warning number.
Some warning messages result in a controlled shut-down of the drive (braking by emergency stop ramp).
The servo amplifier reaction depends on the warning (see STATCODE).
Notes for cause and remedy see Trouble Shooting.
