Inverter Parameter Read/Write Method
4.8.2
Writing the inverter parameters
When data are stored into the corresponding registers of the inverter parameters
(refer to page 110) and the parameter write command is turned from off to on, the data
are written to the parameters that are the targets of all device data. (After that, the
write completion is turned on.)
As soon as the inverter parameter write completion (X29 (RAM) or X2B (E
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
2
X2B (E
PROM)) 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 disable selection" (page 74).
