Warnings and Fault Messages

Valid for S300, S400, S600, S700


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.
Possible reasons and countermeasures are described in the Online Help (Appendix Trouble Shooting)

Faults (errors)

Any faults that occur are shown in coded form by an faults number in the LED display on the front panel. All faults messages result in the BTB/RTO contact being opened, the output stage being switched off (motor loses all torque), and the holding brake is activated.Possible reasons and countermeasures are described in the Online Help (Appendix Trouble Shooting)

Number Description Explanation
D U F Dual Use Firmware

An AL-3A225 (ECCN 3A225) export classified firmware cannot be uploaded to a non Dual Use amplifier. A firmware labeled with "_ND0" must be used.
