Monitoring Functions
Operating mode-specific monitoring functions are:
•
If position limit value monitoring is activated (bit 4 of
S-0-0055,
Position polarities
is set) and the measurement system used for the
operating mode has been homed, the parameter
S-0-0258, Target
position
is monitored for complying with the position limit values
(S-0-0049 or S-0-0050). If these values are exceeded, the
E0253
Target position out of travel range
warning is generated.
The preset target position will not be accepted.
•
If the positioning velocity preset in
S-0-0259, Positioning Velocity
equals zero, the
E2047 Interpolation velocity
=
0
warning is
generated.
•
If the positioning velocity preset in
S-0-0260, Positioning
Acceleration
equals zero, the
E2048 Interpolation acceleration = 0
warning is generated.
•
If the preset positioning velocity (
S-0-0259, Positioning Velocity
)
exceeds the maximum allowed limit value (
S-0-0091, Bipolar velocity
limit value
), the
E2049 Positioning velocity >= S-0-0091
warning is
generated.
The drive will move to the new target position with the velocity from
parameter
S-0-0091, Bipolar velocity limit value
.
•
If the factor of the positioning velocity
S-0-0108, Feedrate override
equals zero, the
E2055 Feedrate-override S-0-0108 = 0
warning is
generated.
•
If the internal numeric range of the position data is exceeded due to
continuous relative positioning, the warning
E2064 Target position
out of num. range
is generated.
Status Messages
The
S-0-0437, Positioning status word
parameter contains all important
status information for this operating mode.
