5. WIRING
• Wiring Instructions
(1) Always connect the power supply via a molded-case circuit breaker (MCCB) to the
power input terminals R/L1, S/L2, and T/L3 (R/L1, S/L2 for single-phase). Never
connect the power supply to U/T1, V/T2, W/T3,-,+1 or +2.
The single-phase (200V class) inverter can be connected to a 200V 3-phase input.
However, when a single-phase supply is used, never use the terminal T/L3 for other
purposes.

(2) Connect the motor wiring to terminals U, V, and W on the main circuit output side
(bottom of the inverter).
(3) If the wiring distance between inverter and motor is long, reduce the inverter
carrier frequency. For details, refer to “Reducing motor noise or leakage current
(n46)” on page 79.
(4) Control wiring must be less than 164ft(50m) in length and separate from the power
wiring. Use twisted-pair shielded wire when inputting the frequency signal
externally.
(5) Tighten the screws on the main circuit and control circuit terminals.
(6) Do not connect or disconnect wiring, or perform signal checks while the power
supply is turned ON.

• Typical setting of V/f pattern
Set the V/f pattern according to the application as described below. For 400V class,
the voltage values (n10, n13, and n15) should be doubled. When running at a
frequency exceeding 50Hz/60Hz, change the maximum output frequency (n09).
Note:
Be sure to set the maximum output frequency according to the motor
characteristics.
Increasing voltage of V/f pattern increases motor torque, but excessive increase may
cause motor over excitation, motor overheat, or vibration.
59
When operating with frequency larger than 60Hz/50Hz, change only maximum output
frequency (n09).
• Full-range automatic torque boost
Motor torque requirement changes according to load conditions. Full range
automatic torque boost adjusts voltage of V/f pattern according to the requirement.
The VS mini J7 automatically adjusts the voltage during constant-speed operation
as well as during acceleration.
The required torque is calculated by the inverter. This ensures tripless operation and
energy-saving effects.
Output voltage
∝
Torque compensation gain (n63) × Required torque
Operation
Normally, no adjustment is necessary for torque compensation gain (n63 factory
setting: 1.0). When wiring distance between the inverter and motor is long or when
motor generates vibration, change the automatic torque compensation gain. In these
cases, it may also be beneficial to adjust the V/f pattern (n09 to n15).

• Example for using the multi-function input terminal as operation reference
(two-wire sequence) follows. For 3-wire sequencing, refer to page 85.
•
Operating (RUN /STOP commands) by communications
(When option card is installed)
Setting parameter n02 to 2 in REMOTE mode can give RUN / STOP commands by
communication (MEMOBUS). For details, refer to page 96.
62
• Selecting Frequency Reference
Frequency reference can be selected by the following methods.
•
Setting by operator
Select REMOTE or LOCAL mode in advance. For the method of selecting the
mode, refer to page 62.
LOCAL mode
Parameter n07 determines where the frequency reference is input from when in the
local mode.
n07 =0: Enables the setting by volume on digital operator (initial setting)

frequency value).
Frequency reference setting is immediately effective when n08 = 1 The ENTER
key does not have to be pressed to enter the reference.
n08 =0: Enables frequency reference acceptance by ENTER key.
=1: Disable frequency reference setting by ENTER key. It is not necessary
to press the ENTER key to accept the reference.
REMOTE mode
Parameter n03 determines where the frequency reference is accepted from when in
the REMOTE mode.
n03 =0: Enables frequency reference setting by volume on digital operator.
=1: Frequency reference 1 (parameter n21) is effective
=2: Voltage reference terminal “FR” is effective (0 to 10V)
(See the figure below)
=3: Current reference terminal “FR” is effective(4 to 20mA)
(Refer to page 90)*
=4: Current reference terminal “FR” is effective (0 to 20mA)
(Refer to page 90)*
=6: Communication (Refer to page 97)

Adjusting speed setting signal
The relationship between the analog input signal and internal (terminal “FR”)
frequency reference can be set by parameters n41 and n42.
FREQUENCY REFERENCE
(a) Frequency reference gain (n41)
The analog input voltage level for the maximum output frequency (n09) can be set
in units of 1%. (maximum output frequency n09=100%)
∗ Factory setting : 100%
(b) Frequency reference bias (n42)
The frequency reference provided when the analog input is 0V (4mA or 0mA) can
be set in units of 1%. (Maximum output frequency n09=100%)
∗ Factory setting : 0%
Example settings:
• To operate the inverter with frequency reference of 0% to 100% at 0 to 5V input
Gain n41 = 200%
Bias n42 = 0%
67
• To operate the inverter with frequency reference of 50% to 100% at 0 to
10V input
Gain n41 = 100%
Bias n42 = 50%
68
Adjusting frequency upper and lower limits
Frequency reference upper (n30) and lower
(n31) limits determines the range over which the
inverter will operate.
• Frequency reference upper limit (n30)
Sets the upper limit of the frequency
reference in units of 1%.
(n09: Maximum output frequency = 100%)
Factory setting: 100%
• Frequency reference lower limit (n31)
Sets the lower limit of the frequency
reference in units of 1%.
(n09: Maximum output frequency = 100%)
When operating at frequency reference 0,
operation is continued at the frequency
reference lower limit.
However, when frequency reference lower
limit is set to less than the minimum output
frequency (n14), operation is not performed.
Factory setting: 0%
Using two accel/decel times
* When “deceleration to a stop” is selected (n04 = 0)
Two acceleration times and two deceleration times can be selected via a multi-function
input. Programming any of terminals S2 through S5 (parameter n36 to n39) to “11”
“Accel/Decel time select”, provides the ability to switch between the 2 acceleration
times (n16 and n18) and deceleration (n17 and n19) through a contact closure applied
to the appropriate terminal (See timing diagram above).
69
At OFF: n16 (accel time 1) are used.
n17 (decel time 1)
At ON: n18 (accel time 2) are used.
n19 (decel time 2)
• Accel time
Set the time needed for output frequency to reach 100% from 0%.
• Decel time
Set the time needed for output frequency to reach 0% from 100%.
(Maximum output frequency n09 = 100%)

Overtorque detection
If an excessive load is applied to the machine, output current increase can be detected
to output alarm signals to multi-function output terminals MA and MB.
To output an overtorque detection signal, set output terminal function selection n40 to
“overtorque detection” [Setting:6 (NO contact) or 7 (NC contact)].

• Overtorque detection level (n60)
Sets the overtorque detection current level in units of 1%. (Inverter rated current =
100%)
Factory setting: 160%
• Overtorque detection time (n61)
If the time when the motor current exceeds the overtorque detection level (n61),
the overtorque detection function operates.
Factory setting: 0.1sec.
73
Frequency detection (n58)
Effective when the multi-function output terminal MA-MB-MC (parameter n40) is set
to “frequency detection” (setting: 4 or 5). “Frequency detection” turns ON when output
frequency is higher or lower than the frequency detection level (n58).
• Frequency detection 1 (Output frequency > Frequency detection level n58)
(Set n40 to “4”.)
• Frequency detection2 (Output frequency < Frequency detection level n58)
(Set n40 to “5”.)
74
Jump frequencies (n49 to n51)
This function allows the prohibit or “jumping” of critical frequencies so that the motor
can operate without resonance caused by machine characteristics. This function is also
used for dead band control. Setting the value to 0.00Hz disables this function.
Set prohibited frequency 1, 2 or as follows:
n49 > n50
If this condition is not satisfied the
inverter displays
for one second
and restores the data to original
settings.
Continuous operation is prohibited within the jump frequency range.
However, during accel/decel the output frequency ramps through the jump frequency
range (without jumping).
Continuing operation by automatic
fault reset (n48)
Sets the inverter to restart and reset fault detection after a fault occurs.
The number of self-diagnosis and retry attempts can be set with n48 (0 thru 10 restarts).
The inverter will automatically restart after the following faults occur:
• OC (overcurrent)
• GF (ground fault)
• OV (over voltage)
The number of retry attempts are cleared to 0 during the following cases:
(1) If no other fault occurs within 10 minutes after retry
(2) When the fault reset signal is ON after the fault is detected
(3) Input power is turned OFF
75
Starting into a rotating motor - Tripless Operation
To start into a coasting motor without trip, use the speed search command or DC
injection braking at start.
• Speed search command
Speed matches into a coasting motor upon starting without stopping the motor.
This function enables smooth switching between motor commercial power supply
operation and inverter operation.
Set input terminal function selection (n36 to n39) to “14” (search command from
maximum output frequency) or “15” (search command from set frequency).
Build a sequence so that FWD (REV) run command is input at the same time as the
search command or after the search command. If the run command is input before
the search command, the search command becomes disabled.
• Time chart at search command input
• DC injection braking at start (n52, n54)
When starting into a coasting motor, use DC injection to gradually brake the motor
before beginning the acceleration ramp. Set the DC injection braking time at start
in n54 in units of 0.1 second. Set DC injection braking current in n52 in units of 1%
(inverter rated current = 100%). When the setting of n54 is “0”, DC injection
braking is not performed and acceleration starts from the minimum output
frequency.
When n52 is set to 0, acceleration starts from the minimum output frequency after
base blocking for n54 setting time.
76
Accel/Decel Hold
To hold acceleration or deceleration, use a multi-function input that is set to a value of
“16: Accel/Decel Hold. The output frequency is kept constant when the accel/decel
hold command is input during acceleration or deceleration.
When the run command is removed during an accel/decel hold condition, accel/decel
hold is internally released and operation ramps to stop.
Set multi-function input terminal selection (n36 to n39) to 16 (accel/decel hold
command).
Note:
When the FWD (REV) run command is input along with the accel/decel hold command, the motor does not operate. However, when frequency reference lower limit
(n31) is set greater than or equal to minimum output frequency (n14), the motor
operates at frequency reference lower limit (n31).

Description
STOP key effective when running either from multi-function input terminals or communications.
When STOP key is pressed, the inverter stops according to the setting of parameter n04. At this
time, the digital operator displays “
” alarm (blinking). This stop command is held in the
inverter until both forward and reverse run commands are open, or until run command from
communications becomes zero.
STOP key is ineffective when running either from multi-function input terminals or
communications.

Description
Deceleration to stop
Coast to stop
• Deceleration to stop (n04 =0)
* When frequency reference is changed during running.
Upon removal of the FWD (REV) run command, the motor decelerates at the decel rate
determined by the time set to decel time 1 (n17) and DC injection braking is applied
immediately before stop. DC injection braking is also applied when the motor
decelerates by setting the frequency reference lower than minimum output frequency
while the(n14) with FWD (REV) run command remains ON.
If the decel time is short or the load inertia is large, an over voltage (OV) fault may
occur during deceleration. In this case, increase the decel time.
82
• Coast to stop (n04=1)
* When frequency reference is changed during running.
Upon removal of the FWD (REV) run command, the motor starts coasting.
Applying DC injection braking
• DC injection braking current (n52)
Sets DC injection braking current level in units of 1%. (Inverter rated
current=100%)
• DC injection braking time at stop (n53)
Sets the DC injection braking time at stopping in units of 0.1 second. When the
setting of n53 is 0, DC injection braking is not performed but inverter output is shut
OFF at the timing of DC injection braking start.
When coast to a stop is selected as the stopping method selection (n04), DC injection
braking at stop does not operate.

• Preventing Motor from Stalling (Current Limit)
This function automatically limits the output current in response to load changes by
adjusting the output frequency to prevent motor stalling.
• Stall prevention (current limit) level during acceleration (n56)
Sets the stall prevention (current limit) level during acceleration in units of 1%
(Inverter rated current = 100%).
Factory setting: 170%
A setting of 200% disables the stall prevention (current limit) during acceleration.
During acceleration, if the output current exceeds the value set for n56, acceleration
stops and frequency is maintained. When the output current goes down to the value set
for n56, acceleration continues.
* Stops the acceleration to prevent the motor
from stalling.
† Release width (hysteresis) of stall prevention
during accel is approx. 5% of inverter rated
current.
*
In the constant horsepower area [output frequency > max. voltage output frequency
(n11)], following equation automatically decreases the stall prevention (current limit)
level during acceleration.
*
*Note: The lower limit of the stall prevention level is 40% of the level set in n56.
91
• Stall prevention (current limit) level during running (n57)
Sets the stall prevention (current limit) level during running in units of 1% (Inverter
current = 100%).
Factory setting: 160%
A setting of 200% disables the stall prevention (current limit) during running.
If the output current during speed agree exceeds the value set for n57 for longer than
100msec, deceleration starts.
As long as the output current exceeds the value set for n57 deceleration continues.
When the output current goes below the value set for n57, acceleration begins to the set
frequency.
The accel/decel rates during stall prevention are determined by the accel time (n16 or
n18) and decel time (n17 or n19) that is selected at the time of the stall prevention
condition.
* Decreases frequency to prevent the motor
from stalling.
† At acceleration start, output hysteresis is
approx. 5% of inverter rated current.

Slip compensation
As the load becomes larger, rotor speed is reduced as motor slip increases. The slip
compensating function regulates the motor shaft speed as the load increases by
increasing the output frequency.
When inverter output current is equal to the motor rated current (n32), the
compensation frequency is added to the output frequency.

The electronic thermal overload function calculates motor temperature, based on
inverter output current and time, to protect the motor from overheating. When the
electronic thermal overload relay is enabled and excessive current is flowing to the
motor, an “
” error occurs, shutting OFF the inverter output and preventing
excessive overheating in the motor. When operating with one inverter connected to one
motor, an external thermal relay is not needed. When operating several motors with
one inverter, install a thermal relay on each motor and disable the electronic overload
protection (n33=2).

• General-purpose motor and inverter motor
Induction motors are classified as general-purpose motors (limited speed range) or
inverter motors (wide speed range), based on their cooling capabilities. Therefore,
the motor overload function operates differently between these two motor types.

Serial transmission is available with VS mini J7 using programmable controller
(MEMOCON series) and MEMOBUS. In order to perform serial communications, RS485/422 interface card (optional) must be installed.
•
MEMOBUS (MODBUS) communications
MEMOBUS system is composed of a single master (PLC) and slaves (1 to 31
VS-mini units).
Transmission between master and slave (serial communication) is controlled
according to the master program with the master initiating communication and the
slave responding.
The master sends a signal to one slave at a time. Each slave has a pre-registered
address No., and the master specifies the number and conducts signal
communication. The slave receives the transmission to carry out designated
functions and reply to the master.

CE Conformance - Electro-Magnetic Compatibility (EMC)
Compliance
In order to conform to EMC standards, exclusive-use methods are required for line
filter application, cable shielding and inverter installation. An outline of the methods
follows.
The line filter and the inverter must be mounted on the same metal plate. The filter
should be mounted as close to the inverter as practical. Keep cable as short as possible.
The metal plate should be securely grounded. The ground of the line filter and inverter
must be bonded to the metal plate with as much area as possible.
For line power input cable, screened cable is recommended at least within the panel.
The screen of the cable should be connected to a solid ground. For the motor cable,
screened cable (max. 20m) must be used and the screen of the motor cable is connected
to ground at both ends by a short connection, using as large an area as practical.
For a more detailed explanation, please refer to Making YASKAWA Inverter Products
Conform with EMC Directive (G-TI#99012-V7).
The following table and figures show the line filter list for EMC standards and the
installation/wiring of inverter and line filter.

Safety Warnings and Operating Information for Inverters
Introduction
Depending on their protection rating configuration, parts of inverters can have live, uninsulated and
hot surfaces during operation. If housing components, the control unit or terminal covers are
removed, incorrect installation and operation can lead to serious injuries and damage to other
installations. It is thus absolutely essential to observe all the warnings and instructions in the
operating manual. Installation, setup and maintenance should only be performed by properly
qualified staff. IEC 364 / Cenelec HD 384 or DIN VDE 0100 and IEC 664 or DIN VDE. The
applicable national safety and accident prevention regulations must also be observed.) For the
purpose of observance of the safety requirement qualified staff are defined as individuals who are
familiar with the installation, setup and operation of the converters and who have the proper
qualifications for this work.
Proper use for intended purpose
Inverters are designed for installation in electrical systems or machines. A converter installed in a
machine may only be activated if the machine conforms to the provisions of EU directive 89/392/
EEC (machine directives). EN 60204 must also be observed. The converter may also only be operated
if the requirements of the EMC directive (89/336/EEC) are also satisfied. This frequency converter
conforms to the requirements of the low voltage directive, 73/23/EEC. The harmonized standards of
the prEN 50178/DIN VDE 0160 series have been applied, in combination with EN 660439-1 / VDE
06600 Part 500 and EN 60146 / VDE 0558. The specifications on the ratings plate and the
specifications and connection requirements described in the documentation must be observed at all
times.
Transportation and storage
All instructions for transport, storage and proper handling must be observed. Climatic and
environmental conditions must conform to the requirements of prEN 50178.
Installation
The converters must be installed and cooled in compliance with the regulations outlines and referred
to in the documentation. The cooling air flow direction is an important requirement that must be
observed. This means that the unit may only be installed and operated in the specified orientation (e.g.
upright). All distances specified must also be observed. The converters must be protected against
excessive stresses. No components may be bent and no distances required for proper insulation may
be changed. To prevent the risk of static electricity damage never touch electronic components or
contacts.
Electrical connections
All national safety regulations (e.g. VBG 4) must be observed when working on live equipment. The
electrical installation of the units must conform to the applicable regulations. For further information
please refer to the documentation. In particular, please take care to observe all installation instructions
regarding proper EMC immunity, e.g. for shielding, earthing, location of filters and cable routing.
This also applies for equipment with CE approvals. Compliance with the EMC legislation limits is the
responsibility of the machine or system manufacturer.
RCCBs
For information on the use of RCCBs with inverters please contact your supplier or Yaskawa
representative.
Operation
In some systems it may be necessary to install additional monitoring and protective facilities to
comply with the applicable safety and accident prevention regulations. The only changes permitted
are to the operator software of the inverters. Please note that the capacitors can remain charged for up
to around 5 minutes after the frequency converter has been disconnected from the power supply. You
should thus always wait for a short period before opening the unit and touching the electrical
connections.
