Diagnostic Messages and Monitoring Functions
Diagnostic Status Messages
The activated "drive-internal interpolation" mode is displayed by one of the
following diagnostic messages:
• A0106 Drive controlled interpolation, encoder 1
• A0107 Drive controlled interpolation, encoder 2
• A0108 Drive controlled interpolation, lagless, encoder 1
• A0109 Drive controlled interpolation, lagless, encoder 2
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 E2053
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.
Status Messages
