The MTR-DCI cannot function independently, i. e. it does not
have its own user program. Records cannot be processed
automatically with a programmed logic. The drive cannot
accomplish any tasks sensibly with Stand Alone; close coup-
ling to the PLC is necessary.
There are also three records with special functions (which
cannot be executed in Record Select mode):
– Set 32 contains the parameters for the Jog mode.
– Set 33 contains the parameters for Direct mode.
– Set 34 is the direct set for the FCT software.
Direct mode
In the direct mode positioning tasks are formulated directly in
the output data of the master.
Positioning mode The typical application calculates dynamically the nominal
target values for each task or just for some tasks. Adaption
to different work item sizes is therefore possible. It is not sen-
sible here to parametrize the record list again each time. The
positioning data are managed completely in the PLC and sent
directly to the MTR-DCI. Here also, close coupling between
the PLC and the MTR-DCI is necessary.
Power operation Alternatively, nominal values relative to the rated motor cur-
rennt can be specified as direct mode. This results in a rotary
torque and with linear drives in a force (power control).
