[Latest] Delta VFD-M Series User Manual PDF Download

Thank you for deciding on delta’s high-overall performance vfd-m series. The vfd-m series is manufactured with extraordinary additives and materials and contain the latest microprocessor era available. This manual is to be used for the set up, parameter placing, troubleshooting, and daily upkeep of the ac motor pressure. To guarantee safe operation of the equipment, read the following protection guidelines before connecting electricity to the ac motor power. Maintain this working manual at hand and distribute to all users for reference.

To make certain the safety of operators and equipment, handiest certified personnel acquainted with ac motor drive are to do set up, start-up and protection. Continually read this guide very well earlier than the use of vfd-m series ac motor pressure, mainly the caution, hazard and caution notes. Failure to comply may also bring about private damage and equipment harm. When you have any questions, please contact your supplier.

Please read prior to installation for safety. AC input power must be disconnected before any wiring to the AC motor drive is made. A charge may still remain in the DC-link capacitors with hazardous voltages, even if the power has been turned off. To prevent personal injury, please ensure that power has turned off before opening the AC motor drive and wait ten minutes for the capacitors to discharge to safe voltage levels. Never reassemble internal components or wiring. The AC motor drive may be destroyed beyond repair if incorrect cables are connected to the input/output terminals. Never connect the AC motor drive output terminals U/T1, V/T2, and

W/T3 directly to the AC mains circuit power supply.

Ground the VFD-M using the ground terminal. The grounding method must comply with the laws of the country where the AC motor drive is to be installed. Refer to the Basic Wiring Diagram. VFD-M series is used only to control variable speed of 3-phase induction motors, NOT for 1-phase motors or other purpose. VFD-M series shall NOT be used for life support equipment or any life safety situation.

DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-voltage. There are highly sensitive MOS components on the printed circuit boards. These components are especially sensitive to static electricity. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands. Only qualified persons are allowed to install, wire and maintain AC motor drives.

Some parameters settings can cause the motor to run immediately after applying power. DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight, high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles. Only use AC motor drives within specification. Failure to comply may result in fire, explosion or electric shock. To prevent personal injury, please keep children and unqualified people away from the equipment. When the motor cable between AC motor drive and motor is too long, the layer insulation of the motor may be damaged. Please use a frequency inverter duty motor or add an AC output reactor to prevent damage to the motor. Refer to appendix B Reactor for details. The rated voltage for AC motor drive must be 240V for 230V models (120V for 115V models;

480V for 460V models; 600V for 575V models) and the mains supply current capacity must be 5000A RMS.

The AC motor drive should be kept in the shipping carton or crate before installation. In order to retain the warranty coverage, the AC motor drive should be stored properly when it is not to be used for an extended period of time. Storage conditions are:

1. Store in a clean and dry location free from direct sunlight or corrosive fumes.
2. Store within an ambient temperature range of -20 °C to +60 °C.
3. Store within a relative humidity range of 0% to 90% and non-condensing environment.
4. Store within an air pressure range of 86 kPA to 106kPA.
5. DO NOT place on the ground directly. It should be stored properly. Moreover, if the surrounding environment is humid, you should put exsiccator in the package.
6. DO NOT store in an area with rapid changes in temperature. It may cause condensation and frost.
7. If the AC motor drive is stored for more than 3 months, the temperature should not be higher than 30 °C. Storage longer than one year is not recommended, it could result in the degradation of the electrolytic capacitors.
8. When the AC motor drive is not used for longer time after installation on building sites or places with humidity and dust, it’s best to move the AC motor drive to an environment as stated above.
