Slow Down Signal Sd; End Limit Signal El+ & El - Leadshine Technology DMC5400 Hardware Manual

4.3 Slow Down Signal SD

The slow down signals (SD0~SD3) are used as input signals for slowing down the speed to the initial speed when
necessary. The following table lists the relative signal name, pin number, and the axis number.

The input circuits of the SD signals are shown as Figure 4.3. Usually, a switch is used to indicate the position
where slowing down is necessary. The specifications of the switches should with contact capacity of +24V, 6mA
minimum. An internal filter circuit is used to filter out the high frequency spike, which may cause wrong
operation. See "Software Manual for the DMC5400 Motion Controller" for more detail operation of the SD.
4.4 End Limit Signal EL+ & EL-
There are two end-limit signals EL+ and EL- for each axis. EL+ indicates end limit signal in positive direction and
EL- indicates end limit signal in minus direction. The relative signal name, pin number and axis number are
shown in the following table.

The switch S1 is used to set the types of EL limit switches, see Table 4-5. The default setting of EL switch type is
"normal open" type limit switch. The switch OFF is to use the "normal closed" type limit switch. The default
setting is set as normal open type.
