1 High- Performance AC DriveMD380MD380 User Manual Preface- 1 -PrefaceThank you for purchasing the MD380 series AC Drive developed by Shenzhen Inovance Technology Co., MD380 series AC Drive is a general-purpose high- Performance current vector control AC Drive . It is an upgrade product based on MD320 and can implement the control of asynchronous motor and permanent magnet synchronous motor (PMSM). It increases the user programmable function, background monitoring software and communication bus function, and supports multi-kind PG cards.

2 It is used to Drive various automation production equipment involving textile, paper-making, wiredrawing, machine tool, packing, food, fan and manual describes the correct use of the MD380 series AC Drive , including selection, parameter setting, commissioning, maintenance & inspection. Read and understand the manual before use and forward the manual to the end The drawings in the manual are sometimes shown without covers or protective guards. Remember to install the covers or protective guards as specified first, and then perform operations in accordance with the instructions. The drawings in the manual are shown for description only and may not match the product you purchased.

3 The instructions are subject to change, without notice, due to product upgrade, specification modification as well as efforts to increase the accuracy and convenience of the manual. Contact our agents or customer service center if you have problems during the MD380 User Manual - 2 -IntroductionCompared with MD320, the MD380 series AC Drive incorporates the following improvements:1) Multiple voltage classesIt provides coverage of single-phase 220 V, three-phase 220 V, three-phase 380 V, three-phase 480 V, three-phase 690 V and three-phase 1,140 ) Control of asynchronous motor and PMSMIt supports vector control of three-phase AC asynchronous motor and three-phase AC ) Diversified control modesIt supports three control modes, namely, sensorless flux vector control (SFVC), closed-loop vector control (CLVC) and V/F ) Multiple communication protocolsIt supports communication via Modbus-RTU, PROFIBUS-DP, CANlink and )

4 Multiple encoder typesIt supports various encoders such as differential encoder, open-collector encoder, resolver and UVW ) All-new SFVC algorithmIt introduces an all-new sensorless flux vector control (SFVC) algorithm that gives better low-speed stability, enhanced low-frequency loading capacity, and supports torque ) User programmable functionThe MD38PC1 programmable card enables you to write programs in ladder diagram. Its programming environment is compatible with that of the H1U series ) Advanced background softwareThe background monitoring software helps to achieve functions of parameter upload & download and a real-time oscilloscope.

5 9) Other new functionsThe newly added functions of the MD380 series AC Drive are described as below:FunctionDescriptionVirtual I/O It can implement various simple logic overheat protectionThe optional MD38IO1 extension card enables AI3 to receive the signal from the motor temperature sensor input (PT100, PT1000) thereby providing motor overheat current limitIt helps to avoid frequent occurrence of overcurrent faults of the AC User Manual Introduction- 3 -FunctionDescriptionMulti-motor switchoverFour motors can be switched over via four groups of motor user parametersIt allows you to save or restore the parameters set by AI/AOThe AI/AO accuracy can reach almost 20 mv via factory correction or on-site correction.

6 Customized parameter displayYou can customize the parameters that need to be displayed. Modified parameter displayYou can view the modified selection at fault occurrenceYou can select the reaction of the AC Drive to a fault occurring, based on the actual need. The reactions are as below: Coast to stop Decelerate to stop Continue to runYou can also select the frequency at which the AC Drive continues to parameters switchoverTwo groups of PID parameters can be switched over via terminals or can be automatically switched over according to feedback loss detectionThe PID feedback loss value can be set to realize PID positive or negative logicYou can set the DI/DO positive or negative response delayYou can set DI/DO response delay dip ride throughIt ensures that the AC Drive continues to run for a short time when an instantaneous power failure or sudden voltage reduction operationThe

7 AC Drive supports timing operation for 6500 minutes at programmable functionThe externally connected programmable card helps you to realize secondary allocationLoad allocation can be implemented between two MD380 series AC drives through point-to-point MD380 User Manual - 4 -Product CheckingUpon unpacking, check: Whether the nameplate model and AC Drive ratings are consistent with your order. The box contains the AC Drive , certificate of conformity, user manual and warranty card.

8 Whether the AC Drive is damaged during transportation. If you find any omission or damage, contact Inovance or your supplier UseFor the users who use this product for the first time, read the manual carefully. If in doubt concerning some functions or performances, contact the technical support personnel of Inovance to ensure correct MarkThe CE mark on the MD380 declares that the AC Drive complies with the European low voltage directive (LVD) and EMC MD380 series AC Drive complies with the following LVD and EMC directives and standards:DirectiveDirective CodeStandardEMC Directive2004/18/ECEN 61800-3EN 55011EN 61000-6-2 LVD Directive2006/95/EECEN 61800-5-1 The MD380 series AC Drive complies with the requirements of standard IEC/EN 61800-3 on the condition of correct installation and use by following the instructions in chapter.
