Introduction

1.1.2Outline of Control Methods

1.1.2Outline of Control Methods

		The VS-616G5 uses four control methods.
		D Open-loop vector control (factory setting)
		D	Flux vector control
		D V/f control without PG
		D V/f control with PG feedback
		PG stands for pulse generator (encoder).
		Vector control is a method for removing interference with magnetic flux and torque, and controlling torque
	1
		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:
		D	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
				(connecting multiple motors to one Inverter).

D V/f control with PG feedback: Simple speed feedback control. (For applications with the PG 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
Characteristic		Vector Control		V/f Control
		Open-loop	Flux Vector	Without PG	With PG feedback
Speed Control		1:100	1:1000	1:40	1:40
Range
Speed Control		±0.2 %	±0.02 %	±2 to 3 %	±0.03 %
Precision
Initial Drive		150% at 1 Hz	150% at 0 r/min	150% at 3 Hz

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.

J V/f Pattern Settings

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.

D Numeric input from the Digital Operator

D Voltage input within a range from 0 to 10 V

DVoltage input within a range from 0 to ±10 V (with negative voltages, rotation is in the opposite direction from the run command.)

1 - 4

1.1 Outline and Functions

D Current input within a range from 4 to 20 mA D Input from Option Card

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.

J PID Control

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			1
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.
D	Speed Control:	With a speed sensor, such as a tacho-generator, the Inverter regulates the rotat-
		ing speed of the motor regardless of the load of the motor or synchronizes the
		rotating speed of the motor with that of another motor.
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
		control.
D	Temperature Control: With a temperature sensor, the Inverter performs temperature control by fan
		speed.

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.

J Speed Control By Feedback

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.

D 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

J User Constant Structure and Three Access Levels

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.

		Table 1.3	Access Levels for User Constants
		Level			Contents
		Mode		Classified according to operation
1
				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-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.)

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.

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.
