• The following shows the required conditions to enable the SQ signal.
Pr.414 setting
1, 11
2, 12
—: Not required to enable the SQ signal
 User parameter (data register (D)) auto storage function selection
• Setting Pr.675 = "1" enables the auto storage function for user parameters.
• The user parameter auto storage function is used to store the setting of Pr.1195 PLC function user parameters 46 (D251)
to Pr.1199 PLC function user parameters 50 (D255) automatically in EEPROM at power OFF or inverter reset.
• The auto storage function is disabled while the inverter performs any of the following. Measurement of the main circuit
capacitor's life, offline auto tuning, emergency drive function, measurement of load characteristics, or PID gain tuning
NOTE
• The auto storage function may fail if the EEPROM is accessed by other functions at the same time at power OFF. To
ensure the auto storage, provide a power source for the control circuit separately from that of the main circuit.
 User parameter reading from EEPROM
• User parameters (Pr.1150 to Pr.1199) are read from RAM or EEPROM according to the settings in Pr.342
Communication EEPROM write selection and Pr.414 PLC function operation selection. When Pr.414 = "11 or 12",
RAM data is read regardless of the Pr.342 setting.
