The IM483 has 4 optically isolated logic inputs which are located on
connector P1. These inputs are isolated to minimize or eliminate electri-
cal noise coupled onto the drive control signals. Each input is internally
pulled-up to the level of the optocoupler supply and may be connected
to sinking outputs on a controller such as the IMS LYNX or a PLC. These
inputs are:
1]
Step Clock (P1:2)
2]
Direction (P1:3)
3]
Enable (P1:5)
4]
Reset (P1:6)
Of these inputs only step clock and direction are required to operate the
IM483.
The schematic shown in Figure 7.5 illustrates the inputs.
