J Wiring
WARNING
D Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire can occur.
D Wiring must be performed by an authorized person qualified in electrical work.
Otherwise, an electric shock or fire can occur.
D Be sure to ground the ground terminal.
(200 V class: Ground to 100 Ω or less, 400 V class: Ground to 10 Ω or less)
Otherwise, an electric shock or fire can occur.
D Always check the operation of any emergency stop circuits after they are wired.
Otherwise, there is the possibility of injury. (Wiring is the responsibility of the user.)
D Never touch the output terminals directly with your hands or allow the output lines to
come into contact with the Inverter case. Never short the output circuits.
Otherwise, electric shock or grounding can occur.
CAUTION
D Check to be sure that the voltage of the main AC power supply satisfies the rated
voltage of the Inverter.
Injury or fire can occur if the voltage is not correct.
D Do not perform voltage withstand tests on the Inverter.
Otherwise, semiconductor elements and other devices can be damaged.
D Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the
I/O wiring examples.
Otherwise, a fire can occur.
D Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.

D Do not connect AC power to output terminals U, V, and W.
The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
D Do not connect phase-advancing capacitors or LC/RC noise filters to the output cir-
cuits.
The Inverter can be damaged or internal parts burnt if these devices are connected.
D Do not connect electromagnetic switches or contactors to the output circuits.
If a load is connected while the Inverter is operating, surge current will cause the overcurrent
protection circuit inside the Inverter to operate.
J Setting User Constants
D Disconnect the load (machine, device) from the motor before autotuning.
The motor may turn, possibly resulting in injury or damage to equipment. Also, motor
constants cannot be correctly set with the motor attached to a load.
J Trial Operation
D Check to be sure that the front cover is attached before turning ON the power supply.
Do not remove the front cover during operation.
An electric shock may occur.
D Do not come close to the machine when the fault reset function is used. If the alarmed
is cleared, the machine may start moving suddenly.
Also, design the machine so that human safety is ensured even when it is restarted.
Injury may occur.
D Provide a separate emergency stop switch; the Digital Operator STOP Key is valid
only when its function is set.
Injury may occur.
D Reset alarms only after confirming that the RUN signal is OFF.Ifanalarmis reset with
the RUN signal turned ON, the machine may suddenly start.
Injury may occur.

tings.
Otherwise, the equipment may be damaged. You must, however, you must set the power supply voltage jumper for 400 V class Inverters of 18.5 kW or higher (see 5.2.4).
J Maintenance and Inspection
D Do not touch the Inverter terminals. Some of the terminals carry high voltages and
are extremely dangerous.
Doing so can result in electric shock.
D Always have the protective cover in place when power is being supplied to the Invert-
er. When attaching the cover, always turn OFF power to the Inverter through the
MCCB.
Doing so can result in electric shock.
D After turning OFF the main circuit power supply, wait until the CHARGE indicator light
goes out before performing maintenance or inspections.
The capacitor will remain charged and is dangerous.
D Maintenance, inspection, and replacement of parts must be performed only by au-
thorized personnel.
Remove all metal objects, such as watches and rings, before starting work. Always
use grounded tools.
Failure to heed these warning can result in electric shock.

Introduction
1.1.2 Outline of Control Methods
1.1.2 Outline of Control Methods
The VS-616G5 uses four control methods.
Open-loop vector control (factory setting)
D
Flux vector control
D
V/f control without PG
D
V/f control with PG feedback
D
PG stands for pulse generator (encoder).
Vector control is a method for removing interference with magnetic flux and torque, and controlling torque
according to references.
Current vector control independently controls magnetic flux current and torque current by simultaneously
controlling the motor primary current and phases. This ensures smooth rotation, high torque, and accurate
speed/torque control at low speeds.
Vector control can be replaced by the conventional V/f control system. If the motor constants required for
vector control are not known, the motor constants can be automatically set with autotuning.
The control methods are effective for the following applications:
Open-loop vector control: General variable-speed drive.
D
Flux vector control: Simple servodrive, high-precision speed control/torque control.
D
V/f control without PG: Conventional Inverter control mode. Used for multi-drive operation
D
(connecting multiple motors to one Inverter).
V/f control with PG feedback:Simple speed feedback control. (For applications with the PG
D
connected to the machine shaft rather than the motor shaft.)
The control characteristics for each mode are shown in Table 1.2.
Table 1.2 Control Method Characteristics
1.1.3 Functions
J Autotuning
Autotuning is effective for vector control. It solves problems in applicable motor restrictions and difficult
constant settings. The motor constants are automatically set by entering a value from the motor’s rating
nameplate.
Autotuning allows flux vector control to operate accurately with virtually any normal AC induction motor,
regardless of the supplier.
Always autotune the motor separately before operating using vector control. Refer to 5.2.5 Autotuning and
6.4.3 Autotuning for details.
J Torque Control
Torque control is effective for flux vector control with PG. Torque is controlled by taking multi-function
analog input signals as torque references. Torque control accuracy is ±5%. Switching is possible between
torque control and speed control.
V/f Pattern Settings
J
V/f pattern settings are effective for V/f control. Select a V/f pattern according to the application from
among the 15 preset V/f patterns. Custom V/f patterns can also be set.

J Frequency References
The following five types of frequency references can be used to control the output frequency of the Inverter.
Numeric input from the Digital Operator
D
Voltage input within a range from 0 to 10 V
D
Voltage input within a range from 0 to ±10 V (with negative voltages, rotation is in the opposite direc-
D
tion from the run command.)
1-4
Current input within a range from 4 to 20 mA
D
Input from Option Card
D
Any of the above frequency references can be used by setting a constant.
A maximum of nine frequency references can be registered with the Inverter. With remote multi-step speed
reference inputs, the Inverter can operate in multi-step speed operation with a maximum of nine speed
steps.
PID Control
J
The Inverter has a PID control function for easy follow-up control. Follow-up control is a control method
in which the Inverter varies the output frequency to match the feedback value from the sensor for a set
target value.
Follow-up control can be applied to a variety of control operations, such as those listed below, depending
on the contents detected by the sensor.
Speed Control: With a speed sensor, such as a tacho-generator,the Inverter regulates the rotat-
D
Pressure Control: With a pressure sensor, the Inverter performs constant pressure control.
D
Flow-rate Control: By sensing the flow rate of a fluid, the Inverter performs precise flow-rate
D
Temperature Control: With a temperature sensor, the Inverter performs temperature control by fan
D
J Zero-servo Control
Zero-servo control is effective with flux vector control. Even at a motor speed of zero (r/min), a torque
of 150% of the motor’s rated torque can be generated and the average servomotor holding power (stopping
power) can be obtained.

control.
speed.
Speed Control By Feedback
J
Speed control using feedback is effective with a PG. An optional PG Speed Control Card be used to enable
feedback control for speeds, thereby improving speed control accuracy.
J Dwell Function
By holding the output frequency for a constant time during acceleration and deceleration, acceleration and
deceleration can be performed without stepping out even when driving a motor with a large startup load.
J Low Noise
The output transistor of the Inverter is an IGBT (insulated gate bipolar transistor). Using sine-wave PWM
with a high-frequency carrier, the motor does not generate metallic noise.
J Monitor Function
The following items can be monitored with the Digital Operator: Frequency reference, output frequency,
output current, motor speed, output voltage reference, main-circuit DC voltage, output power, torque reference, status of input terminals, status of output terminals, operating status, total operating time, software
number, speed deviation value, PID feedback value, fault status, fault history, etc.
All types of data can be monitored even with multi-function analog output.
J Multilingual Digital Operator (SPEC:F)
The Digital Operator can display in seven languages (Japanese, English, German, French, Italian, Spanish,
and Portuguese). The Digital Operator’s liquid crystal display provides a 16-character x 2-line display
area.
Easy-to-read displays in each language allow the advanced functions of the Inverter to be set in interactive
operations to input constants, monitoring items, etc. Change the constant setting to select the display language.
J Harmonic Countermeasures (0.4 to 160 kW Models)
The VS-616G5 Inverters up to 160 kW support DC reactors to easily handle high-frequency control guidelines.
DC reactors (optional) can be connected to 0.4 to 15 kW models.
D
Models from 18.5 to 160 kW have a built-in DC reactor.
D
An optional AC reactor can be connected to Inverters from 185 to 300 kW.

Introduction
1.1.3 Functions
User Constant Structure and Three Access Levels
J
The VS-616G5 has a number of user constants for setting various functions. These user constants are classified into a hierarchy to make them easier to use.
The levels are as follows from top to bottom: Modes, Groups, Functions, and Constants. The access levels
for the user constants are shown in Table 1.3.

Classified by function. (See user constants.)
Individual user constant settings.
The VS-616G5 allows the following three access levels to be set in order to further simplify setting user
constants. (An access level is a range of user constants that can be referenced or set.)

MENU
In general, press the DATA/ENTER Key to move from an upper to a lower level. This varies somewhat,
however, according to the access level, as shown in Fig. 1.1. For the Quick-Start access level, which has
few user constants that can be set, pressing the DATA/ENTER Key jumps directly to the user constant level; whereas for the Advanced access level, which has many user constants, pressing the DATA/ENTER
Key first leads to the Group level.
