Description
Defines the light intensity of the transmission LED of
RDCO module channel CH2. (This parameter is effective
only when parameter 60.1 M/F communication port
set to RDCO CH 2. FDCO modules have a hardware
transmitter current selector.)
In general, use higher values with longer fiber optic
cables.
The maximum setting is applicable to the maximum
length of the fiber optic link. See

Sets a timeout for master/follower (DDCS)
communication. If a communication break lasts longer
than the timeout, the action specified by parameter

As a rule of thumb, this parameter should be set to at
least 3 times the transmit interval of the master.

Selects how the drive reacts to a master/follower
communication break.

Make sure that it is safe to continue operation

Selects the type and scaling of reference 1 received
from the master/follower link. The resulting value is
shown by 3.13 M/F or D2D
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.
