Operation
AX5801 13
3.1.5 Electrical installation
DANGER
Caution - Risk of injury through electric shock!
Disconnect the servo drive from the mains and system voltage before installing the
TwinSAFE drive option card!
Due to the DC link capacitors, there may still be a potentially lethal voltage on the DC
link contacts X02 even after disconnecting the servo drive from the mains supply. Wait
5 minutes after disconnection and measure the voltage on the DC link contacts DC+
and DC-. The device is safe once the voltage has fallen below 50 V.
Configure the safety operation of the servo drive via the drive parameter IDN P-0-2000. The next time the
system is started, the servo drive automatically recognizes whether a TwinSAFE drive option card has
been inserted and whether the parameterization of the IDN P-0-2000 is correct. Error message 0xFDD4
indicates incorrect configuration.
The two relay coils (S1 and S2) must be supplied with 24 V DC via pins 1 and 2 or 3 and 4 of the six-pin
or four-pin plug. Terminals1-1, 2-2, 3-3 and 4-4 of the two connectors are bridged internally.
If the servo drive with the TwinSAFE drive option card does not attain the safe status, the error message
0xFDD5 appears on the display of the servo drive and you must consult Beckhoff without fail.
CAUTION
Danger for persons or equipment!
If an error message appears on the display of the AX5000 the servo drive must not be
put into service if the servo drive in the system or machine represents a safety-relevant
part of the control system.
