ETD750 Series Universal Vector Inverter SAFETY NOTE
ETD 750 Product Manual 6
2.3 Power On 1 Install the cover before switching on the drive, to
reduce the danger of electric shock and explosion.
2
For drives that have been stored for longer than 2 years, increase its input voltage gradually before supplying full rated input voltage to it, in order to avoid electric shock and explosion.
3 Don't touch the live control terminals with bare hands.
4 Don’t operate the drive with wet hands.
2.4 Maintenance 1 Perform the maintenance job after confirming that
the DC Bus voltage is below 36V.
2 Only trained professionals can change the components, it is prohibited to leave wires or metal parts inside the drive so as to avoid the risk of fire.
3 Parameter settings of the control board that has been changed must be revised, otherwise accidents may occur.
2.5 Others 1 Modification is strictly prohibited without permission.
2 Disposing unwanted drives must as industrial waste, strictly prohibit set on fire.
2.6 About Mechanism Load
1
Driving a common motor at low speed for a long time, the drive’s life will be reduced due to the deteriorating heat dissipation effect, so a special variable frequency motor is needed if long time operation with constant torque is required.
2
The drive can protect the motor from over-temperature. If the ratings of the driven motor are not in compliance with the drive, be sure to adjust the protective threshold to ensure the motor is properly protected.
ETD750 Series Universal Vector Inverter SAFETY NOTE
ETD 750 Product Manual 7
3
When running the motor above 50Hz, there will be increase in vibration and noise. The rate at which the torque is available from the motor is inversely proportional to its increase in running speed. Ensure that the motor can still provide sufficient torque to the load.
4
Braking torque is developed in the machine when the drive is hoisting a load down. The drive will trip when it cannot cope with dissipating the regenerative energy of the load. Therefore, a braking unit with proper parameters setting in the drive is required.
5 The output current may fluctuant when drive reciprocating load, especially running in low frequency, recommend running at more than 20Hz.
6
The drive system may encounter mechanical resonance with the load when operating within certain band of output frequency. Skip frequencies have been set to avoid it.
7 Don’t connect or disconnect the motor when the drive running, otherwise will lead to over current or the main circuit may be damaged.
8 Please don’t close to the motor when you use the failure re-start function.
9 Please check the speed allowance range between the motor and mechanism because AC drives can run to high speed easily.
10 Disconnect the motor cable from AC drive before any test to cables.
11 Confirm safety before changing the motor direction.
12 Insure motor terminals not be connected to main power supply.
13 The motor max speed (frequency) must be set according to the motor and devices which connected to the motor.
14Install the motor correctly and ensure the mechanism load can allow the motor start before the motor running.
15 ETD 750 AC drives must be properly earthed from ground terminal.
ETD750 Series Universal Vector Inverter SAFETY NOTE
ETD 750 Product Manual 8
2.7 About AC Drives
1
Don’t connect any varistor or capacitor to the output terminals of the drive, because the drives’ output voltage waveform is pulse wave, otherwise tripping or damaging of components may occur. As following figure:
2 The drive is not suitable to be used out of the specified range of operation voltage. If needed, please use suitable voltage regulation device.
3 There are transient surge suppressors inside the drive which protects it against lighting strike.
4
When using one drive with more motors, we should pay attention to motor load can’t be a reciprocating load, otherwise it will bring instability, and for each motor must have a separate over-current protection device.
KM1~KMn must be matching with motor M1~Mn rated value, in this case, Ac drives can’t protect a single motor.
5 When the Ac drive connected to the power supply, don’t do any measurement to the internal circuit.
6 Ac drives have large capacitive leakage current.
7
When the ac drive connected to the power supply, even if the motor is not running, motor U, V, W terminals and DC Bridges / braking resistor terminals P + / PR is still charged.

8
Although the control I / O terminals and power supply isolation, even if the inverter does not power on, but the relay outputs and other I / O terminals is still possible with a dangerous voltage.
9 If the inverter is used as a part of the machine, the machine manufacturer must provide the machine's main power switch.
10
When the altitude more than 1000 meters, the inverter need for derating due to the thin air cause the inverter cooling effect deterioration. Following is the inverter rated current and altitude curves.
11
When the ac drive connected to the power supply, the inverter power unit is charged. It will be extremely dangerous and even death if touch this voltage. Control unit and the main voltage isolation.
12 Can only use spare parts supplied or recommended by ETD company.
13 ETD750 inverter can only used in a fixed installation.
14Don’t do any voltage test for any part of ETD 750.This test requires a special test procedure. Neglect of the steps will lead to devastating results.

ETD750 Series Universal Vector Inverter SIMPLE OPERATION
ETD 750 Product Manual 39
7. SIMPLE OPERATION 7.1 Inspection and preparation before running
Be sure to check the following items before start: Check the wiring is right or not. Especially check the output terminals U/T1、V/T2、W/T3 can’t connect to power supply, and ensure the grounding terminal is properly earthed. Confirm terminals or the exposure electrification parts are not short-circuited or short to the ground. Confirm terminals connections, pluggable connectors and bolts not loose. When connect to the power supply, make all the switches in open state and ensure the inverter can’t start and there are no unexpected actions. Check the following items after connect to the power supply:
No failure showed on the operator panel. No foreign body in cooling fan of inverter and wind channel
unobstructed.
Switch on the power supply after the cover board be installed. Can’t remove cover board when the power supply on. Can’t operate switches with wet hands to prevent electric shock accidents.
7.2 Operation Methods There are various operation methods, please refer to description of
“Chapter 6 Usage of operation panel” and “Chapter 8 Function parameters list”. Choose the most appropriate operation method according to application requirements and operation requirements. Operation of commonly used methods such as Table 7-1
7.3 Commissioning Verify that no abnormal situation, the right set up all the function
parameters for the inverter running. Do commissioning after set all the parameters done.
ETD750 Series Universal Vector Inverter SIMPLE OPERATION
ETD 750 Product Manual 40
It is recommended running at lower frequency, no abnormal situation then gradually increase running frequency. Default setting to REM3 (remove control), can set by parameter “003” or switch by STOP key.
Table 7-1,Normally used operation methods:
For start press START key, for stop press STOP key. Check following items when running:
Motor rotation direction is right. Motor rotation is smooth (no howling or vibration)。 Acceleration/deceleration is smooth.
If no abnormalities then you can increase frequency from pulse knob .After the commissioning that can be put into operation.
If the inverter or motor operation exception occurs, should immediately stop running and refer to “Chapter 10 Failure Countermeasure” to verify the reasons for abnormal conditions. After the inverter stop output, terminals R/L1,S/L2,T/L3 still live if not disconnected the main contactor. At this time touch terminals U/T1、V/T2、W/T3 will be shocked. In addition, even if remove the main power supply, because of there is charging voltage on filter capacitor, it will take some time to discharge voltage. After remove main power supply 10 minutes and measure the middle dc circuit voltage by multi-meter, confirm the voltage is lower the safety voltage then can touch the internal circuit of inverter.

MODBUS Communication protocol
Modbus communication protocol is applied to electronic controller on the lingua franca. With this agreement, the controller between the controller via the network (such as Ethernet) and other devices can communicate. It has become a common industry standard. With it, different manufacturers of industrial control equipment can be connected into a network for centralized monitoring. This agreement defines the use of a controller can recognize the message structure, regardless of what network they are communicating through. It describes a controller requesting access to other equipment, if the response to requests from other devices, as well as how to detect the error and recorded. It sets the pattern and content of the message the public domain format. When a modbus network traffic, this agreement and decision of each controller, the device need to know their address, identify the address sent by the news and decided what action to generate. If you need to respond, the controller will generate feedback and use Modbus protocol issue. In other networks, messages containing Modbus protocol into the network used in this frame or packet structure. This conversion has also expanded the network address according to specific section addresses, routing paths and error detection method. ETD750 series of AC motor drives using the Modbus networks communication protocols. The Modbus can use the ASCII (American Standard Code for Information Interchange) or RTU (Remote Terminal Unit) two kinds of data coding. ASCII code is the data to be transmitted into the first and then send the corresponding ASCII code, while the RTU is to send data directly, without undergoing conversion. The following instructions encoded ASCII data format.
