can be selected via preset close-loop reference. See
F7.00~F7.07 and F5.20~F5.26 for details.
     Note:
When the PLC operating direction is determined by
operating commands, the direction of the motor can be
controlled by external terminals. For example: to run
forward by closing FWD-COM terminal, and run reverse
by closing REV-COM. If no command is given, the drive
will run in the direction of last stage.
5.6 Close-loop Control Parameters(Group F5)
There are two kinds of close loop control: analog
close-loop control (feedback value is analog value) and
pulse close-loop control (feedback value is pulse). Fig.
5-29 and 5-30 show the typical wiring of analog
close-loop control and pulse close-loop control
respectively.

Fig. 5-30 Wiring of speed close-loop with PG
Analog feedback control system:
An analog feedback control system uses a water-level
sensor as the feedback sensor of the internal PI.
As shown in Fig. 5-29, pressure reference (voltage
signal) is input via terminal VCI, while the feedback
pressure value is input into terminal CCI in the form of
0(4)~20mA current signal. The reference signal and
feedback signal are detected by the analog channel.
The start and stop of the drive can be controlled by
terminal FWD.
The above system can also use a TG (speed measuring
generator) in close speed-loop control
Close speed-loop using PG:
A close speed-loop control system uses external control
terminals X7 and X8, and pulse generator(PG).
As shown in Fig. 5-30, reference of speed close-loop
can be input by a potentiometer in the form of voltage
signal via terminal VCI, while the feedback value of the
close loop is input by PG in pulse mode via terminals X7
and X8. The start and stop of the drive can be controlled
by terminal FWD.
In Fig. 5-30:
A and B are PG’s dual phase quadrature output;
P24 is connected to the power source of PG;
Speed reference is the voltage signal of 0~10V. The
voltage signal is in direct proportion to synchronous
speed n0 that corresponds to 0~Max frequency (F0.05),
and fmax is Max frequency (F0.05), and P is the number
of poles of motor(FH.00).
n0=120×fmax/P
Refer to F7.00~F7.07 for the functions of input terminals
X7 and X8.
     Note:
1. The reference can also be input via panel or serial port;
2. Dual-phase input is good for improving the speed
measurement accuracy, while the wiring of single-phase
input circuit is simple;
3. Dual-phase pulse can only be input in quadrature mode;
4. If using the drive’s terminal P24 to supply the power to
PG, then the Max load current of optical PG must be less
than 100mA.
Operating principles of internal PI of EV2000 is shown in
the Fig. 5-301.

In the above Fig., KP: proportional gain; Ki: integral gain
In Fig. 5-31, refer to F5.01~F5.15 for the definitions of
close-loop reference, feedback, error limit and
proportional and Integral parameters.
There are two features of internal PI of EV2000:
The relationship between reference and feedback can
be defined by F5.08~F5.11.
For example: In Fig. 5-29, if the reference is analog
signal of 0~10V, the controlled value is 0~1MP, and the
signal of water-level sensor is 4~20mA, then the
relationship between reference and feedback is shown
in Fig. 5-32.

Reference

Feedback
Fig. 5-32 Reference and feedback
The reference value is a 0~10V signal (10V corresponds
to 100%); and the feedback value is 4Ma~20mA (20mA
corresponds to 100%).
In Fig 5-31, “reference regulation” and “feedback
regulation” mean that the reference value and feedback
value are converted from current or voltage value to
percentage values, so that feedback value can be added
to or subtracted from the reference value.
Close-loop reference is selected via F5.16 to satisfy
different application requirements.
If the motor’s speed is required to increases with the
reference speed, this kind of control characteristic is
called positive characteristic. If the motor speed is
required to decrease when the reference value
increases, this control characteristic is called negative
characteristic.
Please refer to Fig. 5-33 and F5.16.

After the control type is determined, follow the
procedures below to set close loop parameters.
Determine the close-loop reference and feedback
channel (F5.01 and F5.02);
The relationship between close-loop reference and
feedback value (F5.08~F5.11) should be defined for
close-loop control;
For speed close-loop, the close-loop speed reference
and the number of revolutions of PG (F5.06~F5.07)
need to be determined;
Determine the close-loop regulation characteristic, i.e.
whether the motor speed increase with the reference.
Please see F5.16.
