4.3.4. Memory protection function “prot”
The memory protection function protects the selected memory from being overwritten.
When this function is initiated copying data to the memory is prohibited. Reading the memory data is permitted.
When all the memories are initialized by memory initialization function (clr), the LED indications are as follows:
“in”, “a”, “b”, “c” = “off”, “sup” = “on” This is also the default setting at the time of shipment.
Operating procedure
| Key |
| LED indication |
|
| Key operation and description |
|
|
| “copy” → “comp” | < Selecting a desired function > | ||
|
|
|
| |||
| SFT |
| → “prot” | Select “prot” (memory protection function) with the [SFT] key. | ||
|
|
|
|
| ||
| ENT |
| “prot” → “in” | < Entering the selected function > | ||
|
| After selecting “prot” with the [SFT] key, press the [ENT] key and | ||||
|
|
|
| “in” (selecting inverter memory) appears in the display window. | ||
|
|
|
|
| ||
|
|
|
| < Selecting a memory to protect its data > | ||
|
|
|
| Each time the [SFT] key is pressed, the display changes as follow | ||
|
|
| “in” → “a” → “b” → “c” | “ in” | selecting inverter memory | |
|
|
|
| “ | a” | selecting memory A |
| SFT |
|
| |||
|
| → “sup” → “in” | “ | b” | selecting memory B | |
|
|
|
| “ | c” | selecting memory C |
|
|
|
| “sup” | special parameter selection (*1) | |
|
|
|
| and to “in” again in this order. | ||
|
|
|
| < Entering the memory to protect its data > | ||
|
|
| “in” → “off” | After selecting “in” (selecting inverter memory, by way of example) | ||
| ENT |
|
| with the [SFT] key, press the [ENT] key and the display shows the | ||
|
| “in” → “on” | present memory protection status. (When “on” appears on the | |||
|
|
| ||||
|
|
|
| display, the selected memory is protected. When “off” appears | ||
|
|
|
| on the display, the selected memory is not protected.) | ||
|
|
|
| < Protecting the selected memory > | ||
|
|
| “off” → “on” | Each time the [SFT] key is pressed, the indication in the display | ||
|
|
| changes |
| ||
|
|
|
| “on” | protecting the selected memory (write prohibited) | |
| SFT |
| → “off” | |||
|
| “off” canceling protection of the selected memory (write | ||||
|
|
|
| alternately. | permitted) | |
|
|
|
|
| ||
|
|
|
| < Executing protection of the selected memory > | ||
|
|
|
| After selecting “on” (protecting the selected memory, by way of | ||
| ENT |
| “on” → “prot” | example) with the [SFT] key, press the [ENT] key. Remote Keypad | ||
|
|
|
| starts protecting the selected memory (canceling the protection in | ||
|
|
|
| case of “off”) and the indication in the display window returns to | ||
|
|
|
| “prot”. |
| |
- If the [ESC] key is pressed, Remote Keypad returns to previous status (except when executing).
(*1) The Protecting operation of “sup” is different from that provided for other memories and is shown below.
With the same inverter types (capacity, voltage class)
sup | Standard | Special |
parameters | parameters | |
|
|
|
on | 9 | – |
off | 9 | 9 |
“9”: Protection disabled (write permitted),
With different inverter types (capacity, voltage class)
sup | Standard | Special |
parameters | parameters | |
|
|
|
on | 9 | – |
off (*2) | – | – |
(*2) In this case, copying operation of parameters from one inverter to another inverter of a different capacity or a different voltage class.
