Inverter Parameter Read/Write Method
1.8 Inverter Parameter Read/Write Method
1.8.1 Reading the inverter parameters
When reading the parameter, the parameter description is stored to D9242(D9244) by
storing the parameter number to D9241(D9243) and turning Y28 (Y2A) on. When
reading is completed, X28 (X2A) turns ON to notify the completion. (The device
number within parentheses is used to read the parameter setting value from
EEPROM.)
When reading the calibration parameter (Pr. 902 to Pr. 939), set the following value to
D9234 (D9235) to read each calibration parameter value.
0: Setting value (Frequency/Toruque)
1: Parameter-set analog value
2: Analog value input from terminal
When access error occurs such as "parameter does not exist", value obtained by adding the
parameter number and 8000H is stored to D9150. (Refer to page 33)
