8.14.4 Digital outputs (X3)
Technical characteristics
— Reference ground is digital-GND (DGND, terminal X3/18)
— All digital outputs are floating
— DIGITAL-OUT1 and 2 : Open-Collector, max. 30 VDC, 10 mA
BTB/RTO : Relay output, max. 30 VDC or 42 VAC, 0.5 A
— Update rate : 250 µs
Ready-to-operate contact BTB/RTO
Operational readiness (terminals X3/2 and X3/3 ) is signaled by a floating relay contact.
The contact is closed when the servo amplifier is ready for operation, the signal is not influenced
by the enable signal, the I²t- limit, or the regen threshold.
All faults cause the BTB/RTO contact to open and the switch-off of the output
stage (if the BTB contact is open, the output stage is disabled -> no power).
A list of the error messages can be found on page 88.
Programmable digital outputs DIGITAL-OUT1/2:
You can use the digital outputs DIGITAL-OUT1 (terminal X3/16) and DIGITAL-OUT2 (terminal
X3/17) to output messages from pre-programmed functions that are stored in the servo amplifier.
You can find a list of pre-programmed functions on the "digital I/O" screen of our setup software.
If an input is freshly assigned to a pre-programmed function, then the data set must be stored in the
EEPROM of the servo amplifier, and the 24V auxiliary supply of the servo amplifier must be
switched off and on again (to reset the amplifier software).
Evaluate the outputs via inverting interface relays (see connection diagram), for example
Phönix DEK-REL-24/I/1 (turn-on delay 6 ms, turn-off delay 16ms).
The described logic in the online help of the setup software refers to the output of
the inverting interface relays. Consider the delay of the applied relay !
