8.4.1 Hardware limit protection
D2 drive has a hardware limit protection. The hardware limit is usually the photoelectric switch or micro
switch installed in the positioning platform. It is used to identify the stroke of mechanical movement. When
the motor hits the hardware limit, the emergency brake protection will be activated. Usually, the hardware
limit switch is a normally close sensor. When the hardware limit switch is touched, the drive stops the
motor by using the emergency stop deceleration (“Dec. kill”). At this moment, the drive can only accept
the motion command in the opposite direction.
After clicking
to enter the protection center, select the “HW limit protection” tab to open the
configuration page of hardware limits. To enable the hardware limit protection, the option of “enable HW
limit” (
) must be checked. The digital input pin of hardware limit can be set by clicking the
“Set…” button on this page. Clicking this button will appear the configuration page of I/O center. Refer to
Section 5.5.1 for the setting information.
