4-2 Function Mode Function code Exception code 4 Functions „ To Save the Change to the Holding Register (enter command) Even if using the command to write into the holding register (06h) or into the consecutive holding registers (10h), no change can be saved in the EEPROM memory element of the Inverter. If the Inverter power shuts off without saving any changes, the holding register returns to the status before the changes were made. To save the holding register changes in the Inverter's EEPROM memory element, the "enter command" must be issued according to the following procedure.
To issue the enter command Write into all memory write (holding register number 0900h) using the writing command into the holding register (06h). In this case, a random value can be written into the holding register (0900h). Notes: •The enter command needs considerable time. Monitor the data writing signal (coil number 001Ah) to check whether the data is being written. •Since the Inverter's EEPROM memory element has a limit on the number of rewrites (approx. 100,000 times), the Inverter life may be shortened if enter commands are frequently used. 4-90 Query Exception response 01h 81h 03h 83h 05h 85h 06h 86h 0Fh 8Fh 10h 90h Code Description 01h Specified an unsupported function.
