Speed Monitoring I/O Signals
Door Control Output (DC_Out)
You can use this output for door control in single-axis and multi-axis systems.
This output attempts to maintain last state when a fault occurs.
The DC_Out output is updated based on door control logic status, the P57
[Door Out Type] parameter setting, and any Safe State faults that may be
detected.
This output is Unlocked only when motion is verified to be at Standstill Speed or
Safe Limited Speed.
Figure 8 - Door Control and Lock Monitoring
If an error is detected on either channel of the dual-channel output, a fault occurs.
I/O faults are Stop Category faults, which initiate the configured Safe Stop Type.
The fault is latched until the safety option is successfully reset.
For more information on faults, refer to
.
The DC_Out output may be used as a bipolar output in Power to Release or
Power to Lock configurations, or it may be configured as Cascading (2Ch
Sourcing).
When the Door Control output is configured as cascading (2Ch Sourcing), the
dual-channel bipolar output acts as two sourcing outputs capable of driving the
OSSD Door Monitor input (DM_In) of the next speed monitoring safety option
in the cascaded chain. The DC_out output can also be used as a source for
general purpose inputs. In this configuration, the current is limited to 20 mA.
