Output Signal Schematic
The output signals are all optically isolated using a series of PS2501-4 optical couplers.
The strength of the output signal can be controlled by changing the value of resistors
RP4, RP5 and RP6. These resistors come shipped as 470
Ω
. In some applications, it is
best to remove the resistor altogether. Please consult the user’s manual for your
stepper motor drive or any other output device for the strength of this signal. The end of
this manual contains some sample wiring diagrams for different types of drives. Below
is a schematic for the typical output signal:
Turning off the Controller
Always turn off the Signal Generator when it is not in use.
