Inverter Parameter Read/Write Method

1.8.2Writing the inverter parameters

				Data Access Enable
Device No.	Name	Command Completion		Condition
				(Operation mode)
D9241	Parameter number (RAM)
D9242	Parameter description (RAM)	Y29	X29	Always
D9234	Second parameter changing
	(RAM)
D9243	Parameter number (EEPROM)
D9244	Parameter description			PU, NET operation mode
	(EEPROM)	Y2B	X2B
				(as in Pr.77)
D9235	Second parameter changing
	(EEPROM

Parameter writing is performed when the parameter number is stored to D9241 (D9243) and parameter writing value to D9242 (D9244), and turns ON the Y29 (Y2B). When writing is completed, X29 (X2B) turns ON to notify the completion. (The device number within parentheses is used to write the parameter setting value to EEPROM.) When writing the calibration parameter (Pr. 902 to Pr. 939), set the following value to D9234 (D9235) to write each calibration parameter value.

0:Setting value (Frequency/Toruque)

1:Parameter-set analog value

2:Analog value input from terminal

As soon as the inverter parameter write completion (X29 (RAM) or X2B (EEPROM)) turns on, 0 is set to D9150 on normal completion.

If an error occurs during access to the parameters, e.g. if any value outside the setting range is written or write is performed during inverter operation, the value of parameter No. + H8000 is set to D9150 as soon as the write completion signal (X29 (RAM) or X2B (EEPROM)) turns on, resulting in abnormal completion. If abnormal completion occurs, the parameters are not written. (For example, if an error occurs in the torque boost, H8000 is written to D9150.)

For whether inverter parameter write can be performed or not, refer to Pr.77 Parameter write selection .

POINT

Inverter parameter write must be performed in the PU operation mode or NET operation mode. (Refer to the inverter instruction manual (applied).)
