If a DI terminal is used for the multi-reference function, you need to perform related
setting in group P4.
• 7: Simple PLC
When the simple programmable logic controller (PLC) mode is used as the frequency
source, the running frequency 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 PC.
• 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.
When applying PID as the frequency source, you need to set parameters of PID
function in group PA.
• 9: Communication setting
The frequency is set 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 set frequency. For
details, see the description of group A8.
If PROFIBUS-DP communication is valid and PZD1 is used for frequency setting,
data transmitted by PDZ1 is directly used as the frequency source. The data format is
-100.00% to 100.00%. 100% corresponds to the value of P0-10 (Maximum frequency).
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 P0-10 (Maximum frequency).
The MD380 supports four host computer communication protocols: Modbus,
PROFIBUS-DP, CANopen and CANlink. They cannot be used simultaneously.
If the communication mode is used, a communication card must be installed. The
I5300 provides four optional communication cards and you can select one based
on actual requirements. If the communication protocol is Modbus, PROFIBUS-DP
or CANopen, the corresponding serial communication protocol needs to be selected
based on the setting of P0-28.
The CANlink protocol is always valid.
