COMMAND STRUCTURE I/O CONTROL COMMANDS
PCIx User’s Manual 5-15
5.5.3. HOME CONTROL COMMANDS
System homing is an essential step in most systems. To accommodate a wide range of homing
methods, the following commands provide the ability to set home inputs active high or low and to
enable or disable encoder index signals as part of home detection.
COMMAND PAGE Q = QUERY
C=CMD COMMAND DESCRIPTION
HE 5-86 C Home encoder
HH 5-89 C Home high
HL 5-89 C Home low
HS 5-94 C Home switch
5.5.4. LIMIT CONTROL COMMANDS
Limit conditions are treated as critical errors in the PCIx. When a limit is encountered, the axis
involved will cease motion and flush any pending motion commands for that axis. However,
since needs vary from application to application, the following commands will allow limit behavior
customization to fit almost any system.
