3-2-3 Parameter Read-prohibit Selection (Prohibiting
Data Written to the EEPROM of the Digital
Operator)
·
To store the parameter set values in the EEPROM of the Digital Operator, set n177 for
parameter read-prohibit selection to 0. A protection error (PrE) will be detected by
attempting to read the parameter set values in the Inverter with rEd set. This protects
the parameter set values in the EEPROM from change. The PrE display is turned OFF
by pressing the Mode Key.

EEPROM)

Note 1. No data can be written to n177 unless the default setting is changed. To write
data to this parameter, set n001 for parameter write-prohibit selection/parame-
ter initialization to 4.
Note 2. The parameter setting has an effect on the Digital Operator. If the Digital Opera-
tor with the data in the EEPROM protected is mounted to another Inverter, n117
will be set to 0 regardless of the n117 setting in the Inverter.
