8.15.3 Digital outputs (X3)
Technical characteristics
— Ground reference is Digital-GND (DGND, terminals X4/3 and X4/4)
— All digital outputs are floating
— DIGITAL-OUT1 and 2 : Open Emitter, max. 30 V DC, 10 mA
BTB/RTO : Relay output, max. 30 V DC or 42 V AC, 0.5 A
— Update rate 250 µs
Ready-to-operate contact BTB/RTO
Operational readiness (terminals X3/1 and X3/2 ) is signaled by a floating relay contact.
The contact is closed when the servo amplifier is ready for operation, and the signal is
not influenced by the enable signal, the I²t-limit, or the brake threshold.
All faults cause the BTB/RTO contact to open and the output stage to be switched off (if
the BTB/RTO contact is open, the output stage is inhibited -> no power output). A list of
the error messages can be found on page 112.
Programmable digital outputs DIGITAL-OUT1/2:
You can use the digital outputs DIGITAL-OUT1 (terminal X3/13) and DIGITAL-OUT2 (ter-
minal X3/14) to output messages from pre-programmed functions that are stored in the
servo amplifier.
A list of these pre-programmed functions can be found on the “I/O digital” screen page of
our setup software.
If an output is to be freshly assigned to a pre-programmed function, then the parameter
set must be saved in the EEPROM of the servo amplifier and a reset has to be carried out
(with the amplifier setup software for example).
