2.4 User Outputs
NB: For actual SMC75 connections, see Step motor controllers (SMCxx), page 266.
2.4.2 General
The Controller is equipped with a total of 8 digital outputs. Each output can be used for
a variety of purposes depending on the Controller’s basic mode of operation. The Out
-
puts are not optically isolated from other Controller circuitry. The output circuitry is
powered from the internal power supply CVI. The output circuitry operates with volt
-
ages in the range 5-28VDC. Each output can supply a continuous current up to 350mA.
The outputs are all source drivers, i.e. if a given output is activated, contact is made be
-
tween the control voltage (CVI) and the respective output terminal. See above illustra-
tion.
2.4.3 Overload of User Outputs
All of the outputs are short-circuit protected, which means that the program and the mo-
tor is stopped and the output is automatically disconnected in the event of a short circuit.
The output will first function normally again when the short-circuit has been removed.
Note: Do not connect a voltage greater than 30VDC to the CVI terminal as the output
circuitry may be seriously damaged and the unit will require factory repair.
If one or more outputs are short circuited, MacTalk will show Error “Output Driver” and
Bit2 will be set in Err_Bits
