Cause
Motor feedback configuration
error (for example, a
nonexistent encoder has been
selected as feedback source).
Unexpected motor speed
feedback.
Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost.
Cyclical communication
between drive and fieldbus
adapter module B or between
PLC and fieldbus adapter
module B is lost.
DDCS (fiber optic)
communication between drive
and external controller is lost.
Master/follower
communication is lost.
What to do
Check the settings of parameters
90.41...90.46, and the status of the
source selected in 90.41.
If an encoder is used for motor feedback,
check the settings in groups
module settings, 92 Encoder 1
configuration and 93 Encoder 2
configuration.
Check the settings of parameters
90.41...90.46, and the status of the
source selected in 90.41.
If an encoder is used for motor feedback,
check the settings in groups
module settings, 92 Encoder 1
configuration and 93 Encoder 2
configuration. Check that the encoder is
mounted so that no slippage is possible.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter groups
Fieldbus adapter (FBA),
settings, 52 FBA A data in
data out.
Check cable connections.
Check if communication master is able to
communicate.
Check status of fieldbus communication.
See user documentation of fieldbus
interface.
Check settings of parameter group
Fieldbus adapter (FBA).
Check cable connections.
Check if communication master is able to
communicate.
Check status of controller. See user
documentation of controller.
Check settings of parameter group
DDCS communication.
Check cable connections. If necessary,
replace cables.
Check status of other drives on the
master/follower link.
Check settings of parameter group
DDCS communication.
Check cable connections. If necessary,
replace cables.
