[. . . ] I527-E1-04 USER'S MANUAL SYSDRIVE 3G3MV Multi-function Compact Inverter Thank you for choosing this SYSDRIVE 3G3MV-series product. Proper use and handling of the product will ensure proper product performance, will lengthen product life, and may prevent possible accidents. Please read this manual thoroughly and handle and operate the product with care. 1. To ensure safe and proper use of the OMRON Inverters, please read this USER'S MANUAL (Cat. [. . . ] Note While this function is used, frequency references can only be used in remote mode with the UP/ DOWN command or inching frequency command. All multi-step speed references are disabled. 6-45 Advanced Operation n100 Setting range UP/DOWN Frequency Memory 0, 1 Register Unit of setting 0164 Hex 1 Chapter 6 Changes during operation Default setting No 0 Set Values Value 0 1 Description The frequency on hold is not retained. The frequency on hold for 5 s or more is retailed. Operation of UP/DOWN Function RUN command (Forward rotation) UP command (S5) DOWN command (S6) Output frequency Upper limit Time Time Time Lower limit Status Frequency detection Time Time Note Status U: UP (acceleration) D: DOWN (deceleration) H: Hold U1: Frequency acceleration restricted by upper limit. D1: Frequency deceleration restricted by lower limit. · The following ON/OFF combinations of UP and DOWN commands are possible. Command S6 (UP command) S7 (DOWN command) Acceleration ON OFF Deceleration OFF ON Hold OFF OFF ON ON Hold · With the UP/DOWN function used, the output frequency has the following restrictions for upper and lower limits. Upper limit: Lower limit: The maximum frequency in n011 or the frequency reference upper limit in n033, whichever is smaller. The minimum output frequency in n016 or frequency reference lower limit in n034, whichever is smaller. 6-46 Advanced Operation Chapter 6 · When the RUN command for forward or reverse rotation is input, the Inverter will start operating at the lower limit regardless of whether the UP/DOWN command is input or not. · When the UP/DOWN function and inching frequency command are both assigned to multi-function inputs, an inching frequency command input will have the highest priority. · If n100 for UP/DOWN frequency storage is set to 1, the output frequency held by the UP/DOWN function for 5 s or more will be stored in the memory. The output frequency will be held by the UP/DOWN function when both UP and DOWN commands are ON or OFF together. 6-10-10 Input Open-phase Detection (n166, n167) · The input open-phase detection function is provided for 5. 5- and 7. 5-kW Inverters only. · This function detects the occurrence of an input power supply open phase. The open phase is detected by means of fluctuations in the main circuit DC voltage, enabling detection of power supply voltage fluctuations and imbalances, decreasing values due to ageing of the main circuit capacitor, and so on, in the same way. · If the fluctuations in the main circuit DC voltage exceed the input open-phase detection level (n166), and persist at this level for longer than the input open-phase detection time (n167), a main-circuit voltage fault (PF) will be detected. n166 Setting range n167 Setting range Input Open-phase Detection Level 0 to 100 Input Open-phase Detection Time 0 to 255 Register Unit of setting Register Unit of setting 01A6 Hex 1% 01A7 Hex 1s Changes during operation Default setting Changes during operation Default setting No 0 No 0 Set Values · For the input open-phase detection level (n166), set the main-circuit DC voltage fluctuation level for detecting an input open phase. Set the level as a percentage, as follows: 200-V-class Inverters: Take 400 V as 100%. 400-V-class Inverters: Take 800 V as 100%. · For the input open-phase detection time (n167), set the time (in seconds) for detecting an input open phase. The following values are recommended for detecting an input open phase: n166 = 7 (%); n167 = 10 (s) Note 2. If either n166 or n167 is set to 0, the input open-phase detection function will be disabled. 6-10-11 Output Open-phase Detection (n168, n169) · The output open-phase detection function is provided for 5. 5-kW and 7. 5-kW Inverters only. · This function detects the occurrence of an output terminal open phase. The detection is performed at the current flowing at each output phase. · If the current in any of the Inverter output phases becomes less than the output open-phase detection level (n168) and persists at this level for longer than the output open-phase detection time (n169), an output open-phase fault (LF) will be detected. 6-47 Advanced Operation n168 Setting range n169 Setting range Output Open-phase Detection Level 0 to 100 Output Open-phase Detection Time 0. 0 to 2. 0 Register Unit of setting Register Unit of setting 01A8 Hex 1% 01A9 Hex 0. 1 s Chapter 6 Changes during operation Default setting Changes during operation Default setting No 0 No 0. 0 Set Values · For the output open-phase detection level (n168), set the current for detecting an output open phase. Make the setting as a percentage, taking the Inverter's rated output current as 100%. · For the output open-phase detection time (n169), set the time in seconds for detecting an output open phase.
