Wiring and Connections Section 3-4
Using Pulse Outputs The following diagrams show example applications of sink-type transistor out-
puts using output bits IR 01000 and IR 01001. Use the PULS(65), SPED(
−−),
ACC(
−−), PWM(−−), and SYNC(−−) instructions to produce pulse outputs
(rather than normal outputs) from output bits IR 01000 and IR 01001.
Note *CW is clockwise and CCW is counter-clockwise.
Output Wiring
Precautions
Observe the following precautions to protect the PC’s internal components.
Output Short Protection
The output or internal circuitry might be damaged when the load connected to
an output is short-circuited, so it is recommended to install a protective fuse in
each output circuit. Use a fuse that has a capacity of about twice the output
ratings.
