4.4.2 Digital inputs
The integrated HBI drives have 8 digital inputs, DI1...DI8, which are permanently assigned with different functions. The
DI functions are largely determined by the operating mode (current control, speed control, positioning) selected under
OPTIMISATION / OPERATING MODE
, see the table below.
Digital Inputs DI4 / DI5 are a special case. They can also be used as digital outputs if they are not assigned with an input
function. For available output functions, see chapter 4.4.3
A DI function is activated by default with a signal level of +15...+30V and deactivated with 0...+5V.
Exception: DI function
Limit switch
with parameterisation
Normally closed contacts
inverse level assignment.
The function of the digital inputs DI2, DI3
is additionally dependent on the selection
of limit switch monitoring in the menu
OPTIMISATION / LIMIT SWITCHES.

Description of the DI functions
Pos. / neg. limit switch
The exact function of the limit switches varies depending on the selected operating
mode and limit switch monitoring (see the footnotes below for the table above):
2
Positive setpoints are suppressed; the controller switches to P-
characteristics in order to prevent torques in the positive direction.
Negative setpoints are not influenced.
3
Negative setpoints are suppressed; the controller switches to P-
characteristics in order to prevent torques in the negative direction.
Positive setpoints are not influenced
