4.4.3 Digital outputs
The integrated HBI drives have two digital outputs (DO1, DO2), which can be freely assigned with a function from a
predefined list of functions.
Note:
Each DO pin can alternatively be used as a digital input (DO1/DI5, DO2/DI4).
Therefore, a digital output is only available if the corresponding digital input is not required.
The
following

The function of the digital outputs DO1 and DO2 can be configured in the menu
OPTIMISATION / DIGITAL OUTPUTS
in the parameterisation software DSerV
:
Note:
Both digital outputs are ground
switching open collector outputs. In
order to be able to output a "high"
voltage level, they must be
externally wired with a pull-up
resistor.
(e.g. R = 1k
/ 1W to +24VDC)

capability!
Description of the DO functions
Enable
Active, if the drive is error-free and enabled
Speed threshold
Active, if actual speed > threshold value
Current threshold
Active, if actual current > threshold value
I²t active
Active, if I
2
t limiting is active
Target reached
Active, after successfully completed positioning process.
Ready
Active, if the drive is error-free
Following error threshold
Active, if following error > threshold value
Encoder output channel A/B
Emulation of an encoder output channel, track A/B
(1...20 pulses / revolution)
Note:
Functions which compare an actual value with a specified threshold operate without
debouncing. Minimum time interval for consecutive DO switching edges:
1.5msec
