[. . . ] 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. [. . . ] · Set a multi-function output (n057 to n059) to the following so that the fault retry signal will be output. Set value: 14 for fault retries n082 Setting range Number of Fault Retries 0 to 10 Register Unit of setting 0152 Hex 1 Changes during operation Default setting No 0 Set Values · Set the number of fault retries required. · The count of fault retries will be cleared in any of the following cases. The Inverter is normal for 10 minutes continuously after the latest fault retry was made. A fault reset is input. 6-41 Advanced Operation 6-10-6 Frequency Jump Function (n083 to n086) Chapter 6 · The frequency jump function prevents the Inverter from generating frequencies that make the mechanical system resonate. · The frequency jump function can be used effectively to set three dead bands of a frequency reference. n083 Setting range n084 Setting range n085 Setting range n086 Setting range Jump Frequency 1 0. 00 to 400. 0 (Hz) Jump Frequency 2 0. 00 to 400. 0 (Hz) Jump Frequency 3 0. 00 to 400. 0 (Hz) Jump Width 0. 00 to 25. 50 (Hz) Register Unit of setting Register Unit of setting Register Unit of setting Register Unit of setting 0153 Hex 0. 01 Hz 0154 Hex 0. 01 Hz 0155 Hex 0. 01 Hz 0156 Hex 0. 01 Hz Changes during operation Default setting Changes during operation Default setting Changes during operation Default setting Changes during operation Default setting No 0. 00 No 0. 00 No 0. 00 No 0. 00 Set Values · Set n083 through n085 for jump frequencies 1 through 3 to the central values of jumping frequencies. · Values will be set in 0. 01-Hz increments if the frequency is less than 100 Hz and 0. 1-Hz increments if the frequency is 100 Hz or over. n083 y n084 y n085 · The value in n086 must be set for the jump width. · The operation of the Inverter within the dead bands is prohibited. While the Inverter is in acceleration or deceleration control, however, the Inverter does not jump the bands but changes the frequency smoothly. 6-42 Advanced Operation Frequency Jump Function Output frequency Chapter 6 Reference frequency 6-10-7 Accumulated Operating Time (n087, n088) · The accumulated operating time function is provided for 5. 5- and 7. 5-kW Inverters only. · This function calculates and stores in memory the Inverter's accumulated operating time. The accumulated operating time that is saved can be checked (unit: 10h) by the "accumulated operating time" (U-13) of the multi-function monitor (MNTR indicator). · Use this function in determining the maintenance schedule. n087 Setting range Accumulated Operating Time 0, 1 Register Unit of setting 0157 Hex 1 Changes during operation Default setting No 0 Set Values · Select the operation status to be accumulated. Value 0 1 n088 Setting range Description Accumulate the Inverter's power-ON time (the time from when the power is turned ON until it is shut OFF). Accumulate the Inverter's RUN time (the time that the RUN command is being input). Accumulated Operating Time Selection 0 to 6, 550 Register Unit of setting 0158 Hex 10 H Changes during operation Default setting No 0 · Set the initial value for the accumulated operating time with 10 hours set as 1. Note To clear (i. e. , set to 0) the monitor value (U-13) for the accumulated operating time, set n088 to 0. The monitor value cannot be cleared by setting n001 (parameter write-prohibit selection/parameter initialization) to 8 or 9 (initialize). 6-43 Advanced Operation 6-10-8 Frequency Detection · The 3G3MV has the following frequency detection functions. Frequency Detection: Detects that the frequency reference coincides with the output frequency. Chapter 6 Frequency Detection Levels 1 and 2: Detects that the output frequency is the same as or higher or lower than the set value (frequency detection level) in n095. · The multi-function outputs (n057 to n059) must be set for the frequency detection function. H Frequency Detection · The multi-function outputs (n057 to n059) must be set to the following in order to issue an output indicating that the frequency reference and the output frequency agree. Set value: 2 for frequency agree Frequency Detection Operation Output frequency Detection width ±2 Hz Reset width ±4 Hz Frequency reference Time Frequency detection Time H Frequency Detection Levels 1 and 2 · The parameters in n057 to n059 for multi-function output must be set for frequency detection output. Set value: 4 for frequency detection level 1 (Output frequency y n095) Set value: 5 for frequency detection level 2 (Output frequency x n095) · Set the frequency detection level in n095. n095 Setting range Frequency Detection Level 0. 00 to 400. 0 (Hz) Register Unit of setting 015F Hex 0. 01 Hz Changes during operation Default setting No 0. 00 Set Values · Set the frequency to be detected. 6-44 Advanced Operation Chapter 6 · The value will be set in 0. 01-Hz increments if the frequency is less than 100 Hz and 0. 1-Hz increments if the frequency is 100 Hz or over. Frequency Detection Level 1 Output frequency Reset width ­2 Hz n095 (Frequency detection level) Time Frequency detection level 1 Time Frequency Detection Level 2 Output frequency Reset width +2 Hz n095 (Frequency detection level) Time Frequency detection level 2 Time 6-10-9 UP/DOWN Command Frequency Memory (n100) · This function changes the reference frequency by turning the UP and DOWN commands ON and OFF. · In order to use this function, set n056 for multi-function input 7 to 34.
