Position error and velocity error warnings

In addition to the setting of position error limit described above, D2 drive also provides an early warning
function. When the position error or velocity error exceeds the set value in "Warning windows", the
warning message will be displayed on the "Status" area of main window to warn the user that an
abnormality has occurred in advance.

Brake output

In order to protect the motor and the system structure, D2-series drives provide a brake signal output to
actuate an external electromagnetic brake, which is often used in the Z-direction motor actuation. There
are some timing motion issues in this application. For example, when the motor moves in the Z direction
and the drive receives a disable command, if the brake directly starts at the high speed, the great shock
will be generated to damage the mechanism. In addition, if the motor is disabled early, there is a risk that
the mechanism and the motor may slip. D2-series drives have proprietary brake parameters to reduce
this risk.
Click to enter the protection center and select the "Brake" tab to open the configuration page for
braking timing. The output pin of brake can be set by clicking the "Set..." button on this page. The default
pin is CN2_BRK for frame A - C models and O5 for the frame D model. Click this button to show the
configuration page of I/O center. Refer to Section 5.5.2 for the setting information.
