 6: Multi-reference
In multi-reference mode, state combinations of different DI terminal correspond to
different frequency references. The MD380 supports a maximum of 16 references
implemented by 16 state combinations of four DI terminals (allocated with functions 12
to 15) in Group FC. The multiple references indicate percentages of the value of F0-10
(Maximum frequency).
If a DI terminal is used for the multi-reference function, you need to perform related
setting in group F4.

of the AC drive can be switched over among the 16 frequency references. You can set
the holding time and acceleration/deceleration time of the 16 frequency references. For
details, refer to the descriptions of Group FC.
 8: PID
The output of PID control is used as the running frequency. PID control is generally
used in on-site closed-loop control, such as constant pressure closed-loop control and
constant tension closed-loop control.

function in group FA.
 9: Communication reference
The frequency reference is input by means of communication.
If the AC drive is a slave in point-point communication and receives data as the
frequency source, data transmitted by the master is used as the frequency reference.
For details, see the description of group A8.

transmitted by PDZ1 is directly used as the frequency source. The data format is -F0-
10 to F0-10.
In other conditions, data is given by the host computer through the communication
address 0x1000. The data format is -100.00% to 100.00%. 100.00% corresponds to the
value of F0-10 (Maximum frequency).

CANopen and CANlink. They cannot be used simultaneously.
If the communication mode is used, a communication card must be installed. The
MD380 provides four optional communication cards and you can select one based

or CANopen, the corresponding serial communication protocol needs to be selected
based on the setting of F0-28.
The CANlink protocol is always valid.
