4. Functional Description
In this section, functions added by the installation of the PGFB board, on top of the standard
inverter functions, are described.
4.1.Vector control with sensor
Using the pulse-row feedback signal from the encoder installed on the motor shaft or load
rotation shaft, vector control with sensor can be conducted.
Speed control operation
:0 speed to 150% torque, speed control range 1:1000 (1000 ppr-PG)
speed accuracy ±0.02% (50Hz base digital input)
Torque control operation :Torque control accuracy: ±10% (torque control range: –100% to 100%)
4.1.1.PG feedback wiring
In case of VEC004,VEC005Z,VEC006Z (complementary/open collector)
As for the pulse input signals, A and NA are connected for Phase A, B and NB are connected for Phase B.
The polarity of the pulse input signals should be as follows:
+ side: A, B
- side: NA, NB
The encoder installation direction and signal line wiring should be determined so
that the signal that are fed back from the encoder will show the waveform shown in
Figure 4-1 in terms of the motor rotation direction.
* Forward rotation or reverse rotation is judged from the feedback pulses of Phase A
and Phase B (2-phase pulse that have 90 degrees of phase difference). Therefore, it
should be noted that, when connections are wrong, there is possibility for abnormal
rotation of the motor.

* Caution in case of using open collector encoder connection
In case using pulse command oscillator and open collector encoder, the rise time of the
voltage when the transistor is OFF tends to be longer than the fall time at the time when
the transistor is ON. Therefore, if the maximum input frequency becomes higher, the
pulse duty cannot maintain the 50±10% specification. Conduct derating on the maximum
input frequency so that the pulse duty will be within the following specification range.

The case of VEC007(Line Driver)
As for the PG feedback signals, Terminal A and NA are connected for Phase A, Terminal B
and NB are connected for Phase B.
The polarity of the pulse input signal should be as follows.
Non-inverting input side: A, B
Inverting input side: NA, NB
The signal feedback from the encoder should have the waveform shown in Figure 4-1
in terms of the motor rotation direction. The encoder installation direction and signal
wiring should be done accordingly.
* Forward rotation or reverse rotation is judged from the feedback pulses of Phase A
and Phase B (2-phase pulse that have 90 degrees of phase difference). Therefore, it
should be noted that, when connections are wrong, there is possibility for abnormal
rotation of the motor.

* When using two-phase PG, motor forward and reverse rotation can be judged by PG.
When prohibition on reverse rotation is set by the inverter parameter (f311=1) and
when the motor is rotating to reverse direction due to an external force, the inverter
starts with reverse operation in accordance with the motor’s direction for a time and
the motor will be able to shift to the forward rotation and the smooth startup becomes possible.

The motor constant parameter (f405 to f413) requires setting according to the motor
used.
For details, refer to the inverter manual.
(1) The PG number of input pulses (f375) is the number of encoder output pulses per
one motor rotation.
(2) For PG input phase number selection (f376), set as follows:
If the encoder pulse is single-phase: 1
If the encoder pulse is two-phase (Phase A and Phase B signal): 2
When the settings for the above (1) and (2) are wrong, the motor rotation will become
abnormal.
(3) Even though when setting up the PG disconnection detection f377=2 (Select (Detection of momentary power failure, hardware detection)), if the Selection of number of
PG input phases f376=1(single phase), the detection method is same as
f377=1 (software detection).
When f377 parameter is changed, it is necessary to turn off the power.
(Keep the inverter off until the LED turns off.)
4.1.4.Monitoring method for feedback amount

Note: This function will not be performed if f240 (starting frequency), f241 (operation starting frequency) and f243 (stop frequency) are not set at 0Hz, because a 0 Hz command
is not issued in that case.
* Functions
This function, which is aimed at a retaining the load at standstill at its normal stop position, is
used along with the speed sensor vector control function to prevent the position of an elevator at standstill from shifting.
Switching to position control takes place when the load is at a standstill.
The settings of these parameters take effect only in sensor speed control mode.
In speed control mode 7 or 8 specified with the V/f control mode section parameter (pt),
simple positioning control is performed upon receipt of a simple positioning signal, with the
position at that time used as the reference point (positional deviation: 0).
If the number of PG pulses is smaller than the area of f381, that signal can be output on a
terminal block that is set to the 118 as output terminal function.

If the stop position control command is entered during high-speed operation, a trip may occur
because of overcurrent or overvoltage. To avoid this, do not enter the stop position control
command before the motor enters into low-speed operation.
If a trip occurs because of overvoltage when stop position control is performed
If a trip due to overvoltage (op2 or op3) occurs when the motor is decelerated by stop
position control, reduce the proportional (P) gain with f362 to prolong the deceleration
time.
Note: The deceleration time setting (dec) has no effect during stop position control.

4.2.Pulse input command (speed command selection)
It is possible to input inverter operation frequency command by pulse signals.
This command cannot be used when vector control operation with sensor is effective.
- Inverter output frequency can be controlled in ratio with the pulse output signal from the
pulse oscillator.
- By inputting two-phase pulse with 90 degrees phase difference, it is possible to input forward and reverse rotation commands.
4.2.1.Pulse command connection method
Two-phase pulse input command
1. Connect pulse input signal to the point between terminals A and NA on phase A and for
between terminals B and NB on phase B
2. The polarity of the pulse input signals should be as follows:
+ side: A and B
- side: NA and NB
3. Forward and reverse operation can be judged by the pulse from the phase A and B by
using a judgement circuit together with the operational frequency command.
4. The judgement on forward and reverse rotation is made as shown in Figure 4-5.

The case for single-phase pulse input command
For the pulse input signal, connect between A and NA.
For switching between forward and reverse rotation, with cmod= 0 (Terminal input validation), ON and OFF actions between Terminal F-CC and R-CC are used.

4.2.3.Monitoring method of pulse input command
The pulse input command frequency can be monitored.
In order to monitor the pulse input command frequency, set up the monitor display in the
frequency command value [Unit: Hz/free unit].
The pulse input command frequency can be confirmed even before the motor is used.
Initial value can be confirmed for the combination testing.
For setting method of the condition monitor, refer to the inverter instruction manual in the
“monitoring operation condition” section.
