E8044 Negative travel range limit switch activated
Travel range limit switch situated in negative
direction (see Project Planning Manual for motor)
was activated because axis is outside of travel range
that was defined by means of travel range limit
Incorrect parameterization of digital inputs and
outputs on control section
Travel range limit switch or cable is defective or
Control section or digital inputs on control section
Supported by Firmware Variant:
The drive provides a function for monitoring travel range limit switches
(external hardware limit switches). This monitor has to be activated and
parameterized via P-0-0090, Travel range limit parameter.
When the warning E8044 occurs, the axis is shut down with
velocity command value reset.
Set drive enable and input a command value leading
back to allowed travel range
Correct configuration of digital inputs/outputs on control
section and correct it, if necessary
Check function and wiring of travel range limit switch
Replace control section or entire drive controller
Only Rexroth service engineers or especially trained users are
allowed to replace the control section. The replacement of the
entire drive controller is described in the Project Planning
Manual for the power section.
