3.2.2 Connection of In-position and Alarm
In Position
In-position signals is set by SW8, can be sent out when the targeted position is in the “Target” range (see
parameter
Distance to Send "In position" Output Signal
in software manual) to external devices such as relays, motion controllers,
PLCs, IO boards, etc.
Alarm
Alarm signals can be sent out when occurs over-voltage, over-current, or position following error, etc. This output can
be used to drive devices such as a relay, a LED, etc., or as an input signal to electronic devices like a PLC.
For example, in a multi-axis system like a CNC machine when one of the axes fails such a fault output signal can be
feedback to the motion controller for a followed action (e.g., auto machine shutdown, auto error clearing, etc.).
Connection
Refer to the following figure.
Figure 4: ALM Signals Connection
3.2.3 Connection of Brake Signal
This signal can be used for automatic brake control while system power failure.
When use a 24V electromagnetic relay, it is recommended to connect a diode (such as IN4007) in parallel, the polarity
should not be reversed. The specific connection is as follows figure.
When use a solid-state relay (SSR), its advantages are fast response, no need to add diodes, no noise; specification such
as “Non-contact, DC control DC, current limit protection 0.6-10A”.
