There are several ways of detecting a possible fault:
-
LEDs on the module front panel.
-
Diagnostic screens which can be accessed by the DIAG key in online mode from all the application-specific axis control module screens.
-
Debug screens.
-
Fault bits and status words
The following conditions must be fulfilled in order to execute movement commands (in automatic or manual mode):
-
The axis is configured and is without a blocking fault.
-
The speed controller validation command ENABLE (%Qr.m.c.9) is active and the command STOP (%Qr.m.c.15) is inactive.
-
Automatic or manual mode is selected.
-
For commands in absolute position, the position is:
-
between SL_MIN (%MDr.m.c.33) and SL_MAX (%MDr.m.c.31) ranges for a limited axis,
-
between values of 0 and modulo –1 for an unlimited axis.
-
For commands on a relative position, the target calculated from the current relative position is between the limits SL_MIN and SL_MAX.
-
The axes are referenced, except for the reference point commands.
-
The SMOVE function parameter F is equal to VMAX.
Modifying the CMV Parameter
If modifying a CMV speed modulation parameter implies a resulting speed greater than VMAX, this speed is limited to VMAX.
If the Sequence control option has not been selected in the configuration, a non-stop movement followed by no sequencing command will continue as far as a soft stop.
