3.2 WIRING THE MAIN CIRCUIT

WA R NI N G

●Make sure to ground the ground terminal (Ground resistance 220V class：100Ω or less. 440V class：10Ω or less)

Failure to observe this warning can result in an electrical shock or a fire.

CAUTION

●Never connect the AC main circuit power supply to output terminals U,V and W.

The inverter will be damaged and invalidate the guarantee.

(1)Wiring Precautions for Main Circuit Input

(a)Installation of Molded-case Circuit Breaker (MCCB)

Make sure to connect MCCBs of fuses between AC main circuit power supply and TG-300 input

terminals L1, L2 and L3 to protect wiring.

(b)Installation of Ground Fault Interrupter

When connecting a ground fault interrupter to input terminals L1, L2 and L3, select one that is not

affected by high frequency.

(c)Installation of Magnetic Contactor

Inverters can be used without a magnetic contactor (MC) installed at the power supply side. When

the main circuit power supply is shut OFF in the sequence, a magnetic contactor (MC) can be used

instead of a molded-case circuit breaker (MCCB). However, when a magnetic contactor is switched

OFF at the primary side, regenerative braking does not function and the motor coasts to a stop.

● The load can be operated/stopped by opening/closing the magnetic contactor at the primary side.

However, frequent switching may cause the inverter to malfunction.

● When using a braking resistor unit, use a sequencer to break power supply side on overload relay

trip contact. If the inverter malfunctions, the braking resistor unit may be burned out.

(d)Terminal Block Connection Sequence

Input power supply phases can be connected to any terminal regardless of the order of L1, L2 and L3

on the terminal block.

(e)Installation of AC Reactor

When connecting an inverter (220V/440V 15Kw or less) to a large capacity power supply

transformer (600Kva or more), or when switching a phase advancing capacitor, excessive peak

current flows in the input power supply circuit, which may damage the converter section. In such

cases, install a DC reactor (optional) between inverter 1 and 2 terminals or an AC reactor

(optional) on the input side. Installation or a reactor is effective for improvement of power factor on

the power supply side.

10

(f)Installation of Surge Suppressor

For inductive loads (magnetic contactors, magnetic relays, magnetic valves, solenoids, magnetic

brakes, etc.) connected near the inverter, use a surge suppressor simultaneously.

(g)Prohibition of Installation of Phase Advancing Capacitor

If a phase advancing capacitor or surge suppressor is connected in order to improve the power factor,

it may become overheated and damaged by inverter high harmonic components. Also, the inverter

may malfunction because of overcurrent.

(2)Wiring Precautions for Main Circuit Output

(a)Connection of Terminal Block and Load

Connect output terminals U, V and W to motor lead wires U, V and W. Verify that the motor rotates in the forward direction (CCW：counterclockwise when viewed from the motor load side) with the

forward run command. If the motor rotation is incorrect, exchange any two of output terminals U,V

or W.

(b)Strict Prohibition of Connection of Input Power Supply to Output Terminals

Never connect input power supply to output terminals U, V and W.

(c)Strict Prohibition of Short Circuiting or Grounding of Output Circuit

Never touch the output circuit directly or put the output line in contact with the inverter case.

Otherwise, it may cause an electrical shock or grounding. In addition, never short circuit the output

line.

(d)Prohibition of Connection of Phase Advancing Capacitor or LC/RC Noise Fitter

Never connect a phase advancing capacitor or LC/RC noise, filter to the output circuit.

(e) Avoidance of Installation of Magnetic Starter

Do not connect a magnetic starter or magnetic contactor to the output, circuit.

If the load is connected while the inverter is running, the inverter overcurrent

protective circuit operates because of inrush current.

(f) Installation of Thermal Overload Relay

An electronic overload protective function is incorporated into the inverter.

However, connect a thermal overload relay when driving several motors with one inverter or when

using a multi-pole motor. When using a thermal overload relay, set inverter constant H033 to 0.

Additionally, for thermal overload relay, at 50Hz set the same rated current value as that described

on the motor nameplate, or at 60Hz 1.1 times larger than the rated current value described on the

motor nameplate.

11

(g) Wiring Distance between Inverter and Motor

If the total wiring distance between inverter and motor is excessively long and the inverter carrier

frequency (main transistor switching frequency) is high, harmonic leakage current from the cable

will adversely affect the inverter and peripheral devices.

If the wiring distance between inverter and motor is long, reduce the inverter carrier frequency as

described below. Carrier frequency can be set. by constant H050.

Wiring Distance between Inverter and Motor

Wiring Distance between

Up to 50m Up to 100m More than 100m

(3)Grounding

●Ground resistance 220 V class：100Ω or less, 440 V class：10Ω or less

●Never ground TG-300 in common with welding machines, motors, or other large-current electrical

equipment. Run all the ground wires in a conduit separate from wires for large-current electrical

equipment.

●Use the ground wires described in tables below and keep the length as short as possible.

●When using several TG-300 units side by side, ground the units as shown below

for:

●The voltage and frequency characteristics of motor

●The maximum rotation speed of motor

*2 Select high starting torque only in the following conditions. Normally, this selection is not

required.

●The wiring distance is long (150 m and above).

●Voltage drop al startup is large.

●AC reactor is inserted in the input or output of the inverter.

●A motor smaller than the nominal output of the inverter is used.

27

(2)Custom V/f Pattern

6 .6 ADJUST NG MOTOR TORQUE (1) Torque Compensation Gain (H067)

Motor torque requirement changes according to load conditions. Full-range automatic torque boost

adjusts voltage of V/f pattern according to the requirement. The TG-300 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

●Operation

→Increase voltage

f (Frequency)

Normally, no adjustment is necessary for torque compensation gain (H067 factory setting: 1.O).

When the wiring distance between the inverter and the motor is long, or when the motor generates

vibration, change the torque compensation gain.

Increasing torque compensation gain increases motor torque, but an excessive increase may cause

the followings:

●Inverter malfunctions because of motor overexcitation

●Motor overheat or excessive vibration

Increase torque compensation gain gradually while verifying the motor current.

6 .7 MOTOR PROTECTION (1) Motor Overload Detection

The inverter protects against motor overload with a built-in electronic thermal overload relay.

(a) Motor Rated Current (H032)

Set to the rated current value shown on the motor nameplate.

(b) Motor Overload Protection Selection (H033)

Setting Electronic Thermal Characteristics

0 No protection

1 Standard motor (time constant 8 min)(Factory

setting)

2 Standard motor (time constant 5 min)

3 Inverter motor (time constant 8 min)

4 Inverter motor (time constant 5 min)

The electronic thermal overload function monitors motor temperature, based on inverter output

current and time, to protect the motor from overheating.

When electronic thermal overload relay is enabled, an "OL1" 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. In this case,

set constant H033 to 0.

6 .9 ENERGY SAVING CONTROL

To enable energy saving control, set energy saving selection (H095) to 1

Setting Description

0 Energy saving is disabled

1 Energy saving is enabled

Since the constants used in the energy saving control mode have been preset at the factory to the

optimum values prior to shipment, it is not necessary to adjust them under normal operation. If your

motor characteristics differ greatly from those of SHANGCHIN. standard motors, refer to the

following description to change the constants.

(1) Energy Saving Control Mode

(a) Energy Saving Gain K2 (H096)

Use this energy saving gain when running in the energy saving control mode to calculate the voltage

at which motor efficiency will be greatest, and set it as the output voltage reference. This value is

preset at the factory to the SHANGCHIN standard motor value prior to shipment. As the energy

saving gain increases, output voltage increases also.

(b) Energy Saving Voltage Lower Limit (H097 , H098)

Sets the output voltage lower limit. If the voltage reference value calculated in the energy saving

mode is smaller than the specified lower limit, this lower limit value is output as the voltage

reference value. The lower limit value is set in order to prevent stalling at light loads. Set voltage

limits at 6Hz and 60Hz

；a value obtained by linear interpolation should be set to any limit values

other than at 6Hz or 60Hz. Setting is made as a percentage of motor rated voltage.

(2) Energy Saving Tuning

In the energy saving control mode, the optimum voltage is calculated according to load power, and

the voltage is supplied to the load. However, the set constant may vary due to temperature variations

or using other manufacturers' motors, therefore, the optimum voltage may not be supplied in some.

cases. Automatic tuning controls voltage so that highly efficient operation is maintained.

(a) Voltage Limit of Tuning (H100)

Limits the range to control voltage by tuning .Setting is made in a percentage of motor rated voltage.

By setting this value to 0, tuning is disabled.

(b) Step Voltage Of Tuning (H100 , H101)

Sets voltage variation width of one tuning cycle. Setting is made in a percentage of motor rated

voltage. By increasing this value, the rotating speed variation becomes larger. This voltage variation

width is set when starting tuning voltage is 100% and motor rated voltage is 5%. Values obtained by

linear interpolation are set to any voltage values other than these values.

6 .10 MODBUS CONTROL

TG-300 can perform serial transmission by using a programmable controller (PLC) and MODBUS

communication. MODBUS is composed of one master PLC and 1 to 31 (maximum) slave units

( TG-300 ). In signal transmission (serial transmission) between the master and slaves, the master

always starts transmission and the slaves respond to it.

The master performs signal transmission with one slave at one time. Therefore, address numbers are

assigned to each slave in advance and the master specifies a number to perform signal transmission.

The slave which receives the command from the master executes the function and returns the

response to the master.

(1) Communication Specifications

●Interface

●Synchronization

●Transmission parameter

●Data length

●Parity

●Stop bit

：Fixed to 8 bits

：Parity / no-parity, even / odd selectable (constant H108)

：Fixed to 1 bit

●Protocol

●Maximum number of units to be connected

2) Data to be Sent/Received by Communication

(

：RS-485, RS-422 (Communication interface card S-T/P must be mounted.)

：Asynchronous ：●Baud rate ：Selectable from 2400, 4800, 9600 BPS (constant H107

：In accordance with .MODBUS

：31 units (when RS-485 is used)

Data to be sent/received by communication are run commands, frequency reference, fault contents,

inverter status and constant setting/reading.

(a) Operation Mode Selection (H002)

Select the run command and frequency reference input method in constant H002.

To provide a run command and frequency reference by communication, set this constant to settings 4

to 8. Also, without regard to this selection, monitoring of running status, constant setting/reading,

fault reset and multi-function input command from the PLC are enabled. The multi-function input

command becomes OR with the command input from control circuit terminals S2 to S6.

(b) Modbus Frequency Reference Unit (H105)

The frequency reference units from the PLC and in the frequency reference and output frequency

monitors (by communication) are selected.

The output frequency resolution of the TG-300 is 0.1 Hz. Even if the frequency reference unit is

changed to 0.01 Hz in constant Hl05, the value in the hundredth digit of 0.01 Hz of the received

frequency reference is rounded off internally. When 30000/100% in units of 0.1% is selected, the

value is rounded off in the same way.

(

c) Modbus Slave Address (H106)

The slave address number is set. It is necessary to set the address number so that it will not overlap

with the address number of another slave connected on the same transmission line.

Note：

To change the values set in constants Hl06 to Hl08 and enable new settings, it is necessary to turn

OFF the power supply, and then turn it ON again.
