SMCI12
Connections and circuits
Signal states at the outputs (SMCI12 with RS485 firmware)
Note:
In the SMCI12-3 with CANopen firmware, the status of the controller is not displayed
at the outputs.
The following table shows the possible signal states at the outputs 1 to 3:
Signal states
Meaning
Output 3
Output 2
Output 1
0
0
Rotation monitoring (error) or limit switch
0
1
Motor idle (waiting for new command).
1
0
Busy (control processing last command).
1
1
Reference point or zero point reached
1 Overtemperature
The outputs can be freely programmed using the NanoPro software.
Note
:
Output 3 is also used to display errors and when switching on the controller.
Input circuits
Note:
The voltage must not exceed 5 V. It should drop below 2 V for safe switching off and
be at least 4.5 V for safe switching on.
Output circuits
The outputs are transistor outputs in Open-Collector circuits (0 switching, max. 24
V/0.5 A). An LED can be integrated to test the output. The LED lights up when the
output is active.
Issue: V 1.0
