Causes
In the EtherCAT communication of the
driver module, in the ESM state is SafeOP
or OP, phasing servo and communication
(PLL lock) was separated.
In the EtherCAT communication of the
driver module, more than the threshold
value that the omission of the interruption
processing by SYNC0 or IRQ set up by bit0
to 3 of Pr7.42 (Maximum continuation
communication error) in after the
completion of synchronous processing
generated.
Protective Functions
Measures
<In case of DC>
 Check setting of DC mode.
 Check whether propagation delay
compensation or drift compensation is
correct.
<In case of SM2>
 Check whether the transmitting timing of
PDO from host controller is constant.
 Check whether there is any problem in
wiring of the EtherCAT communication
cable.
 Check whether there is excessive noise
on the EtherCAT communication cable.
If the error cannot be resolved, shut off and
reset the control power.
<In case of DC>
 Check setting of DC mode.
 Check whether propagation delay
compensation or drift compensation is
correct.
<In case of SM2>
 Check whether the transmitting timing of
PDO from host controller is constant.
 Check whether there is any problem in
wiring of the EtherCAT communication
cable.
 Check whether there is excessive noise
on the EtherCAT communication cable.
 The preset value of Pr7.42 (Maximum
continuation communication error) bit0-3
is enlarged.
If the error cannot be resolved, shut off and
reset the control power.
