Wiring Length of Encoder Cable
Do not exceed 20 m for the wiring length of the encoder cable. If the wiring length should be 20 m
or longer by necessity, use a relay amplifier that specifies 5 V line driver output. In this case, be
careful of the following points for wiring.
To use a relay amplifier, the wiring length between the PG Board and the relay amplifier must be
within 20 m. Check the input specifications of the relay amplifier to determine the wiring length between the relay amplifier and encoder. (Confirm with the relay amplifier manufacturer.)
If the wiring length is longer than that specified, the Inverter could work erroneously due to influence from the outside noise at that point. Be careful of the relay amplifier wiring.
The encoder cable could be easily influenced by outside noise depending on the shielding method
of the shield cable, resulting in an Inverter failure. Generally connect to the power supply ground
of a signal line or to the ground for shielding. (To connect to the ground, be careful of the ground
cabling route and avoid multi-point grounding.)
To use a PG Board encoder power supply for the interface power supply between the PG Board
and relay amplifier, adopt a shielding method following "Mounting the Ferrite Cores" (page 2-5). A
different method can be applied, however, for the power supply from a source other than the PG
Board. If using a relay amplifier, also follow "Mounting the Ferrite Cores" (page 2-5) for the connection of the ferrite cores.

Mounting the Ferrite Cores
The ferrite core mounting method is shown below.
Mount the two provided ferrite cores as below when connecting the encoder cable.
Connect the wire to the EG5 terminal of the 3G3AX-PG Board through the ferrite cores for shielding.
If the ferrite cores cover the shield coating, they fail to work effectively, causing the Inverter to malfunction. Be sure to fix the ferrite cores or take other appropriate measures so that they do not overlap the shield coating.
The shield wire connected to the terminal could become disconnected due to the weight of the ferrite
cores. Be sure to fix the ferrite cores or take other appropriate measures so that the shield wire does
not receive the weight of the ferrite cores.

Note 1: For the terminal connection on the Inverter, refer to the Inverter 3G3RX User’s Manual.
Note 2: For the signal line, use a twisted shield wire and apply the shield coating as illustrated be-
low. Keep the length to 20 m or less. If the wiring length should be 20 m or more by necessity, use a VX application control device RCD-E(remote control device), or CVD-E
(insulated type signal converter). For the encoder line, use a twisted shield wire of 0.75 mm
2
or more. Keep the length to 20 m or less. If the wiring length should be 20 m or longer by
necessity, use a relay amplifier that specifies 5 V line driver output.

Operation
3-2 Precautions for Operation
Operation
For operation, refer to “Chapter 3 Operation” of the Inverter 3G3RX User’s Manual. When operating
the RUN command from the terminal block side of the Inverter, follow the procedure below.
1. Supply power to the Inverter.
2. Set the V/f characteristics selection (A044) to “05”.
3. Set the necessary items according to “Chapter 4 Functions” of the Inverter 3G3RX
User’s Manual.
4. For speed control, operation starts according to each setting when the Inverter RUN
command is turned ON.
5. For position control, turn ON the STAT terminal, and turn ON the Inverter RUN command. When inputting the pulse train position command between SAP and SAN,
and between SBP and SBN, the motor rotates according to the input pulse.
Test Run
Check the following items for a test run.
• Does the motor accelerate normally?
• Is the motor rotation direction correct?
• Is there any abnormal vibration or noise in the motor?
Check whether the phase sequence is correct if the motor does not accelerate normally or an Inverter overload trip is observed in the test run. If the waveform of phase A is 90° ahead of that of
phase B in forward rotation, the phase sequence can be said to be normal.
Note 1: In some cases, monitor signal is not output from the “MP” terminal of Inverter if the Inverter
runs without the motor connected and with the control method set to “05” (sensor vector
control) in the Inverter function mode “A044”. With “05” set, check the motor output after
connecting the motor with an encoder.
Note 2: Do not perform free running through the RS terminal allocated to the multifunction input of
the Inverter during operation. Otherwise, an overcurrent trip or power element breakage
may occur. Use the FRS terminal allocated to the multifunction input of the Inverter for free
running during operation.
Note 3: With a large value set for torque limit (b041 - b044), an overcurrent trip may occur during
load application. Adjust the torque limit set value to avoid this.
Note 4: Perform auto tuning if the motor parameter is unknown.

4-1 V2 Control Mode Selection
Select a control method in V2 control mode selection P012.
When “00” (ASR) is selected in P012, speed control mode is enabled. Select a frequency reference
in frequency reference selection A001.
When “01” (APR) is selected in P012, the Inverter enables position control by generating frequency
reference based on the position command pulse input from the pulse train position command input
terminal, and on the position feedback detected by the encoder.
Select any of the three pulse train position command input modes in pulse train mode selection
P013.
To perform pulse train position control, allocate “48” (STAT) to any of the multi-function input terminals. While the STAT terminal is tuned on, pulse train position command input is accepted.
Position deviation can be cleared through external input. Allocate “47” (PCLR) to any of the multifunction input terminals. Turning ON/OFF the PCLR terminal can clear position deviation data.
Allocating “22” (DSE) to any of the multi-function output terminals enables excessive speed deviation signal output.
Set a deviation level in speed deviation error detection level P027. When the deviation between real
frequency and reference frequency exceeds the P027 set value, the DSE signal turns on.
When “02” (APR2) or “03” (HAPR) is selected in P012, the Inverter performs absolute position control with reference to the absolute position from its origin.

Functions
4-2 Sensor Vector Control (speed control)
To use this function, set V/f characteristics selection A044 to “05” (V2), and V2 control mode selection P012 to “00” (speed control).
(“Sensor vector control” can be selected for 1st control only.)
To use this function, make sure that the motor parameter settings are suitable for your motor. For
details, refer to “Chapter 4 Functions, 4-2 Function Mode, Moter Parameter Selection” in the general-purpose Inverter 3G3RX User’s Manual.
Also, be sure to set the number of your encoder pulses.
With V2 control mode selection P012, you can select four types of control modes: Speed control,
Pulse train position control, Absolute position control, and High-resolution absolute position control.
Note the following before use:
•
Sufficient characteristics may not be obtained if you select a motor size two or more ranks lower
than the motor size specified.
•
If the Inverter does not normally accelerate, or if overload protection is activated, check the phase
sequence of the encoder signal.
(If phase A is advanced by 90° from phase B during forward
run, it is judged as being normal.)
When running the Inverter with V/f characteristics selection A044 set to “00” (VC), you can
check the rotation direction with real frequency monitor d008.
(If positive frequency is detected when the forward command is activated, or if negative frequency is detected when the reverse command is activated, the rotation direction is judged as
being normal.)
If sensor vector control cannot provide the desired characteristics, adjust the motor parameters depending on the phenomenon, as shown in the table below.
Note 1: Make sure that the carrier frequency (b083) is not lower than 2.1 kHz. If the carrier frequency is at 2.1 kHz or
lower, the Inverter will not operate normally.
Note 2: To use a motor with a capacity lower than that of the Inverter, set a torque limit value (b041 to b044), while
keeping the value
α
in the following formula at 200% or lower.
Otherwise, the motor may burn out.
α
= Torque limit set value × (Inverter capacity) / (Motor capacity)
(Example)
If the Inverter capacity is 0.75 kW and the motor capacity is 0.4 kW, the torque limit set value for α =
200%, calculated with the above formula, is as follows:
Torque limit set value (b041 to b044) = α × (Motor capacity) / (Inverter capacity)
= 200%
×
(0.4 kW) / (0.75 kW) = 106%

Torque Bias Function
This function applies bias to the torque reference generated in speed control, and is useful for elevating
applications.
*1. When torque bias is set to the
FE terminal, −10 to +10 (V) is recognized as −200 to +200 (%).
*2. • When “00” (As per sign) is selected:
When the polarity of a torque bias signal is (+), the torque increases for forward rotation, and when it is (
−
), the
torque increases for reverse rotation, regardless of the RUN direction.
• When “01” (Depends on the RUN direction) is selected:
The torque bias signal polarity and torque bias direction vary depending on the RUN command direction.
Forward command: Applies torque in the same direction as the torque bias.
Reverse command: Applies torque in the opposite direction of the torque bias.

Functions
Torque Control
This function can be used in torque control, as well as in the speed and pulse train position controls.
Torque control can be applied to winders, and more.
To run the Inverter in torque control mode, allocate “52” (ATR) to any of the multi-function inputs.
While the ATR terminal is turned on, the torque reference input is enabled.
With torque reference input selection P033, you can select either each analog input or the input via
the Digital Operator.
The torque control speed depends on the balance between torque and load. To prevent the Inverter
from running out of control, set a speed limit value in P039 (forward) or P040 (reverse).

Electronic Gear Function
This function allows you to set a gain relative to position command or position feedback and to
change the main/sub motor rotation ratio, particularly for synchronous operation.
Note: Below are the block diagrams of the electronic gear function.
*1. It is recommended that position control feedfoward gain adjustment should be started with P022 = 2.00. To
reduce the position deviation between the main and sub motors, increase the position control feedforward gain.
If motor hunting occurs, reduce the position control feedforward gain.
*2. It is recommended that position loop gain adjustment should be started with P023 = 2.00. To increase positioning
accuracy and holding power, increase the position loop gain. If an increased position loop gain causes hunting,
reduce the position loop gain.
*3. Make sure that the N/D setting is within the range of 1/50 ≤ N/D ≤ 20.

Functions
Example: Synchronous Operation
For the Inverter (master Inverter) on the main motor side, you can select either the speed control or
pulse train position control mode.
For the Inverter (slave Inverter) on the sub motor side, you need to select the pulse train position
control mode.
Configuration Example
• Main motor : Number of encoder pulses = 1024
• Sub motor : Number of encoder pulses = 3000
• Main motor rpm : Sub motor rpm = 2:1
For operation under the above conditions, set the following data in the slave Inverter.
Pulse train mode selection (P013) : 00 (pulse with 90° phase difference)
Electronic gear setting position selection (P019) : 01 (REF)
Electronic gear ratio numerator (P020) : 3000
Electronic gear ratio denominator (P021) : 1024
× 2 = 2048
The following shows an example of the ratio of slave rpm to master rpm depending on the P019 to
P021 settings.
(Note that the same number of encoder pulses (1024 pulses) should be set on both Inverters.)

Functions
Motor Gear Ratio Setting Function
This function is useful for a system with an optional encoder installed on the machine side.
Set the number of actual encoder pulses in encoder pulses P011.
Set a motor-to-encoder rpm ratio in motor gear ratio numerator/denominator P028/P029.
With the above settings, the number of encoder pulses converted into motor shaft data is set in the
Inverter.
This function performs speed/position detection based on the number of encoder pulses converted
into motor shaft data, and calculates the orientation stop position based on the number of encoder
pulses (P011).
Note: Make sure that the N/D setting is within the range of 1/50
≤ N/D ≤ 20.
(N: Motor gear ratio numerator, D: Motor gear ratio denominator)
<Example>
When the motor-to-encoder rpm ratio is 1:10, set the following data.
• Number of encoder pulses (P011) : 1024
• Motor gear ratio numerator (P028) : 10
• Motor gear ratio denominator (P029) : 100
In this case, the orientation stop position is defined as 4096 divisions of the encoder’s one rotation.
Note that the concept of the stop position is inverted from the description in "Orientation stop position conceptual drawing" (page 4-14).
Position Bias Function
Set this function to apply position command bias in the pulse train position control mode.
The set number of pulses is added to a change value at 2 ms intervals. This is used for adjusting
the phase of synchronization points during synchronous operation.
Set an addition value in position bias amount P024. A positive value adds the value in the forward
direction.

4-3 Pulse Train Position Control Mode

Functions
(1) When the RUN command is turned ON with the ORT terminal turned ON, the Inverter accelerates to the orientation
speed (P015), and then performs constant speed operation.
(If the RUN command is input during operation, the operation speed changes to the orientation speed when the ORT
terminal is turned ON.)
(2) After the orientation speed is reached, the Inverter shifts to the position control mode when the first Z-pulse is
detected.
(3) During forward run, position control is performed with a target value of “Orientation stop position (P014) + one
rotation”; During reverse run, with a target value of “Orientation stop position (P014) + two rotations”.
In this step, the higher the position loop gain (P023), the shorter the deceleration time (regardless of the deceleration
time setting).
(4) After the remaining number of pulses reaches the position ready range setting (P017), the Inverter outputs the POK
signal after the position ready delay time setting (P018) elapses. (The POK output remains until the ORT signal is
turned OFF.)
After positioning is completed, the servo lock status remains until the RUN command is turned OFF.
Note 1: Do not set a high frequency for the orientation speed, because positioning must be completed within two
rotations during deceleration. Otherwise, an overvoltage trip may occur.

Absolute Position Control Modes
To use the absolute position control mode, set V/f characteristics selection A044 to “05” (V2), and
V2 control mode selection P012 to “02” (APR2: absolute position control).
When “03” (high-resolution absolute position control) is selected in V2 control mode selection P012,
control is based on
×4 the number of pulses used for internal operations.
(Set the multi-step position command and position range specification for
×4 multiplication control.)
The position command can be changed up to 8 steps, depending on combinations of multi-function
inputs.
Zero return speed can be selected from one low speed and two high speeds.
(The orientation function, described in the previous section, is not available.)
By using the teaching function, you can set the position command while running the machine.
By allocating “73” (SPD) to a multi-function input, you can switch between the speed and position
controls.
For data with many digits (e.g. position command), only the higher 4 digits are displayed.

Functions
Absolute Position Control Operation
In the absolute position control mode, the Inverter moves to the target position according to the following parameter settings, and is then set in the position servo lock status.
• Position command
• Speed command (frequency reference)
• Acceleration/Deceleration time
(The servo lock status is retained until the RUN command is turned OFF.)
The frequency reference and acceleration/deceleration command for absolute position control conform to the parameters selected when the RUN command is ON.
If the position command is set to a low value, the Inverter may start deceleration and perform positioning before the speed command value is reached.
In the absolute position control mode, the direction of RUN command (FW or RV) does not refer to
the rotating direction. The FW or RV signal starts or stops the Inverter. The Inverter runs forward
when (Target position
− Current position) is a positive value, or runs in reverse when it is a negative
value.
If you do not perform zero return operation, the position at power-on is regarded as the origin (position = 0).
When position command is set to zero, position ready is set when the RUN command is turned ON.
In reset selection C102, select “03” (trip reset only).
* If reset selection C102 is not set to “03”, turning ON the Inverter’s reset terminal (or RESET key)
clears the current position counter. To operate the Inverter by using the current position counter
value after resetting a trip by turning on the reset terminal (or RESET key), be sure to set reset
selection C102 to “03”.
If PCLR is allocated, turning on the PCLR terminal clears the current position counter.
(The internal position deviation counter will be simultaneously cleared.)
The absolute position control mode disables the ATR terminal. (Torque control is disabled.)
The absolute position control mode disables the STAT terminal. (Pulse train position control is disabled.)
The absolute position control mode disables the orientation function.
(However, the ORT terminal is used for teaching, as described later.)

Multi-step Position Switching Function (CP1/CP2/CP3)
By allocating “66” to “68” (CP1 to CP3) to any of multi-function inputs 1 to 8 (C001 to C008), you
can select from multi-step positions 0 to 7.
Set position commands in multi-step position commands 0 to 7 (P060 to P067).
If no position command is allocated to the terminals, multi-step position command 0 (P060) is defined as the position command.
When you input a multi-step position command, you can set the wait time until the terminal input is
determined. This prevents the transition status from being applied before it is determined.
You can adjust the determination time in multi-step speed/position determination time C169. If no
input is made during the time set in C169, the data is determined after the set time elapses. (Note
that the longer the determination time, the slower the input response.)

Speed/Position Switching Function (SPD)
This function is used for speed control operation.
Allocate “73” (SPD) to any of the multi-function inputs.
While the SPD terminal is turned ON, the current position counter is retained at zero. The Inverter
shifts to the position control mode when the SPD terminal is turned OFF during operation. (Speed/
Position switching)
With the position command set to 0, the Inverter shifts to the stop operation when the SPD terminal
is turned OFF
(Hunting may occur, depending on the position loop gain setting.)
While the SPD terminal is turned ON, the Inverter runs in the direction specified by the RUN command. To shift from speed control to position control, be careful about the polarity sign of the RUN
command.

Zero Return Function
This function performs three types of zero return operations according to the zero return mode
P068. When zero return is complete, the current position is cleared to zero.
You can select the zero return direction in zero return direction selection P069.
If zero return is not performed, the Inverter performs position control with the position at power-on
defined as the origin.
(1) The Inverter accelerates to the low-speed zero
return frequency according to the acceleration

Functions
Forward/Reverse Run Stop Function (FOT/ROT)
With a signal from the control range limit switch, this function prevents the Inverter from running outside the specified operation range.
The torque limit is set to 10% on the forward side when the FOT terminal is turned on, and on the
reverse side when the ROT terminal is turned on.
This function can be used as the limit switch at the machine end, when “71” (FOT) and “72” (ROT)
are allocated to any of multi-function inputs 1 to 8 (C001 to C008).
Position Range Specification Function
Set a forward/reverse position control range in position range specification (forward) P072 and position range specification (reverse) P073. If the current position counter exceeds this setting range,
the position control range trip (E63.* or E73.*) occurs, and the Inverter goes into free-run status.
The upper limit setting of multi-step position commands 0 to 7 is limited by this position range setting.
(You cannot set a position command beyond the position range.)
Teaching Function
This function starts or stops the motor at a desired position and stores the current position in a desired position command area.
Allocate “45” (ORT) to any of multi-function inputs 1 to 8 (C001 to C008).
When V2 control mode selection P012 is set to “02” (absolute position control) or “03” (high-resolution absolute position control), the relevant terminal serves as a teaching terminal.
<Teaching Procedure>
(1) In teaching selection P074, select the position command you want to set.
(2) Move the workpiece.
• Input the RUN command with the ORT terminal turned ON. At this time, the speed command
and acceleration/deceleration time conform to the currently selected parameters.
* If the Inverter control circuit (Ro, To) is turned on, teaching is enabled.
The current position counter operates even if the workpiece is moved by an external device.
Teaching is therefore enabled even while the Inverter is stopped.
Note: Make sure that the Inverter power circuit (R/L1, S/L2, T/L3) is turned off. Also, make sure
that the Inverter’s output (U/T1, V/T2, W/T3) is disconnected from the motor. Not doing so
may result in injury and/or damage to the equipment.

Servo ON Function
This function brings the Inverter into speed servo lock status via an input terminal when “05” (sensor
vector control) is selected in V/f characteristics selection A044.
Allocate 54 (SON) to the desired multi-function input.
The Inverter will not accept the RUN command unless the SON terminal is turned on when SON is
allocated.
If the SON terminal is turned off during operation, the Inverter goes into free-run status. When the
SON terminal is turned on again, the Inverter restarts according to the setting of free-run stop selection b088.
This function cannot be simultaneously used with the preliminary excitation function (55: FOC). If
FOC and SON are both allocated to multi-function inputs, priority is given to FOC, and SON is disabled.

Functions
Pulse Train Frequency Input
This function allows you to use a pulse train input to the SAP-SAN terminals on the PG Board as
frequency reference or PID feedback value in each control mode.
(This function can be used in all control modes.)
Set the input frequency at the maximum frequency in pulse train frequency scale P055.
The analog input start/end function cannot be used. To limit the input frequency, use pulse train frequency bias amount P057 and pulse train frequency limit P058.

You can select whether to trip the Inverter or continue operation ignoring an error when the optional
PG Board causes an error.
Note:Even if 01 has been selected in operation selection at option error, the Inverter trips when an
encoder disconnection error (E60, E70) or
3G3AX-PG connection error (E69, E79) occurs.
