Fieldbus Interpolator:
Invalid modulo
settings Reaction 1: Downramp actual
speed; remain in position
control state.
Create the prerequisites for the command:
Setting the Master (Cmd 2,3) only if "global enable" (O3020.4) is
not placed.
Prepare coupling by change-over (Cmd 4, C3_CamIn,C3_CamOut)
only if coupling / decoupling is not taking place at the same time.
Prepare quadratic coupling (Cmd 5,7, C3_CamIn) only if coupling is
not taking place at the same time and if the Master has already
been set.
Prepare quadratic decoupling (Cmd 6,8, C3_CamOut) only if
coupling is not taking place at the same time and if the Master has
already been set.
Set master position for display (Cmd10, C3_SetMaster) only if not
synchronized (coupling or decoupling resp. curve mode).
Set master position in Mode relative/absolute (Cmd11/12/13,
C3_CamTableSelect) only without master position enable for Cam
(O3030.17 = 0).
Resetting the curve generator (Cmd23, C3_CamReset) only if not
synchronized (coupling or decoupling resp. curve mode).
The last CamCmd declined for this reason (O3010.1 = -3) can be
read out via O3010.3 (LastNAKCommand).
74A4 29860
Invalid modulo
settings for fieldbus
actual position Reaction 1: Downramp actual
speed; remain in position
control state.
Correct specification for selected curve (O3011.2) and/or start line
of the curve (O3040).
74A5 29861
Overflow during
calculation of the
fieldbus actual
position modulo
Reaction 1: Downramp actual
speed; remain in position
control state.
Select valid coupling segment (O3011.3) or verify curve memory.
7590 30096
HEDA
synchronization error Reaction 2: Downramp /
apply brake / de-energize..
Select valid segment or verify curve memory.
7591 30097
HEDA communication
error Reaction 2: Downramp /
apply brake / de-energize.. Specify permitted value for master segment distance (O3056) or
master segment factor (O3058).
7592 30098
HEDA Acyclic
Receiver Overrun
Reaction 1: Downramp actual
speed; remain in position
control state.
Load curve data into the device or reduce number of segments.
7593 30099 HEDA PLL failure
Reaction 2: Downramp /
apply brake / de-energize.. Check master reset distance used (very short or zero (deactivated))?
Check contents of O1139.4 or O1140.5.
7594 30100
HEDA Cyclic Receiver
Overrun Reaction 2: Downramp /
apply brake / de-energize.. Verify, if the configuration used makes sense. Send the
configuration and cam data to technical support.
8110 33040
Receive buffer
overflow Reaction 2: Downramp /
apply brake / de-energize..
Verify the current segment (O3031.1) with reference to its sequence
at the selected coupling / decoupling positions (O1139.1 and
=1140.1) (the gradient of the segment must be positive and
unequal to zero) and the selected delta values (O1139.4 and
=1140.4). Please note that the coupling/decoupling positions
(O1139.1 and O1140.1) are corrected into number range 0..master
reset distance.
8120 33056
CANopen/DeviceNet:
CRC error or passive
mode (CAN
controller)
Reaction 1: Downramp actual
speed; remain in position
control state. Verify the default values numerator (O3011.5) and/or denominator
of the reset distance (=3011.6). Verify the configuration of master
and master signal sources.
