DAttach the Inverter to a metal or other noncombustible material.
Fire can result if the Inverter is attached to a combustible material. NO TAG
DInstall a cooling fan or other cooling device when installing more than one Inverter in
the same enclosure so that the temperature ofthe airentering the Inverters is below
45_C.
Overheating can result in fires or other accidents.

DWiring must be performed by an authorized person qualified in electrical work.
Otherwise, an electric shock or fire can occur. NO TAG
DBe sure to ground the ground terminal.
(200 V class: Ground to 100 :or less, 400 V class: Ground to 10 :or less)
Otherwise, an electric shock or fire can occur.
NO TAG
DAlways 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.) NO TAG
DNever touch the output terminals directly with your hands or allowthe output linesto
come into contact with the Inverter case. Never short the output circuits.
Otherwise, electrical shock or grounding can occur.

DCheck 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.

1.1 Outline and Functions
The VS-626 MC5 Inverter is a compact spindle drive specially designed for machine tool application. MC5
Inverter has features such as winding change during operation, and autotuning function for dual windingmo-
tors.
TheVS-626MC5Invertersprovidesfull-currentvectorcontrolbasedonadvancedcontrollogic. Anautotuning
function is included for easy vector control.
The Digital Operator provides a liquid crystal display that is 2 lines by 16 characters in size. User constant set-
tings and monitor items areeasily read in interactive operations in either Japaneseor English. (The display lan-
guage can be changed by setting a user constant.)
1.1.1 VS-626MC5 Inverter Models
VS-626MC5 Inverters are availablein 200 and 400 Vclass models.These are listed in the followingtable.
A total of 32 models is available for motor capacities of 0.4 to 75 kW.

1.1Outline and Functions

1.1.2 Outline of Control Methods
The VS-626MC5 uses two control methods.
DOpen-loop vector control (factory setting)
DFlux vector control
PG stands for pulse generator (encoder).
Vectorcontrolisamethod for removinginterferencewith magneticfluxandtorque,and controllingtorque
according to references.
Current vector control independently controls magnetic flux current and torquecurrent by simultaneously
controlling the motor primary current and phases. Thisensures smooth rotation, high torque, and accurate
speed/torque control at low speeds.
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:
DOpen-loop vector control: General variable-speed drive.
DFlux vector control: Simple servodrive, high-precision speed control/torque control.
The control characteristics for each mode are shown in Table 1.2.

1.1.3 Functions
JAutotuning
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 allowsfluxvectorcontrol tooperateaccuratelywith virtually anynormalACinductionmotor,
regardless of the supplier.
Always perform autotuning for motor unit separately before vector control operation.
JFrequency References
The followingfive types offrequency referencescan be used tocontrol the output frequency of theInvert-
er.
DNumeric input from the Digital Operator
DVoltage input within a range from 0 to 10 V
DVoltage input within a range from 0 to r10 V (with negative voltages, rotation is in the opposite direc-
tion from the run command.)
DCurrent input within a range from 4 to 20 mA
DInput from Option Card
Any of the above frequency references can be used by setting a constant.
Amaximumofninefrequencyreferencescanbe registeredwiththeInverter. Withremotemulti-stepspeed
reference inputs, the Inverter can operate in multi-step speed operation with a maximum of nine speed
steps.
JLow 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.

JMonitor Function
The following itemscan be monitored with the Digital Operator: Frequency reference, output frequency,
output current, motor speed, output voltage reference, main-circuit DC voltage, output power, torqueref-
erence,status of input terminals, status of output terminals, operating status, totaloperating 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.
JBilingual Digital Operator
The Digital Operator can display either English or Japanese. The Digital Operator’s liquid crystal display
provides a 16-character x 2-line display area.
Easy-to-read displays 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 English display.
JHarmonic Countermeasures (0.4 to 160 kW Models)
The VS-626MC5 Inverters support DC reactors to easily handle high-frequency control guidelines.
DDC reactors (optional) can be connected to 0.4 to 15 kW models.
DModels from 18.5 to 75 kW have a built-in DC reactor.
JUser Constant Structure and Three Access Levels
The VS-626MC5 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.
Table 1.3 Access Levels for User Constants
Level Contents
Mode Classified according to operation
Operation: For operating the Inverter. (All kinds of monitoring are possible.)
Initialize: For selecting the language displayed at the Digital Operator, set-
ting access levels, initialization, and the control modes.
Programming: For setting user constants for operation.
Autotuning: For automatic calculation or setting motor constants. (Only under
the vector control mode.)
Modified constants: For referencing or changing user constants after shipping.
Groups Classified by application.
Functions Classified by function. See user constants.
Constants Individual user constant settings.
The VS-626MC5 allows thefollowing 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.)
Quick-Start Reads/sets user constants required for trial operation. [Factory setting]
Basic Reads/sets user constants that are commonly used.
Advanced Reads/sets all the user constants that can be used.
