Description
Drive trips on 7510 FBA A
though no control is expected from the fieldbus.
Drive generates an A7C1 FBA A communication
This occurs even though no control is expected from the
fieldbus.
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Defines the time delay before the action defined by
parameter 50.02 FBA A comm loss func
starts when the communication link fails to update the
message.
As a rule of thumb, this parameter should be set to at least 3
times the transmit interval of the master.
Note: There is a 60-second boot-up delay immediately after
power-up. During the delay, communication break
monitoring is disabled (but communication itself can be
active).
Time delay.
Selects the type and scaling of reference 1 received from
fieldbus adapter A.
Note: Fieldbus-specific communication profiles may use
different scalings. For more information, see the manual of
the fieldbus adapter.
Type and scaling are chosen automatically according to
which reference chain (see settings Torque, Speed,
Frequency) the incoming reference is connected to. if the
reference is not connected to any chain, no scaling is
applied (as with setting Transparent).
No scaling is applied (the 16-bit scaling is 1 = 1 unit).
Generic reference with a scaling of 100 = 1 (i.e. integer and
two decimals).

scaling.
Selects the type and scaling of reference 2 received from
fieldbus adapter A.
See parameter 50.04 FBA A ref1
Selects the type/source and scaling of actual value 1
transmitted to the fieldbus network through fieldbus
adapter A.
Note: Fieldbus-specific communication profiles may use
different scalings. For more information, see the manual of
the fieldbus adapter.
Type/source and scaling follow the type of reference 1
selected by parameter 50.04 FBA A ref1
individual settings below for the sources and scalings.
The value selected by parameter
transparent source is sent as actual value 1. No scaling is
applied (the 16-bit scaling is 1 = 1 unit).
