Chapter 12 Inverter Functions
12.17 Operating the Inverter in
Conjunction with the System
12.17.1 Using by Switching between Two
Settings
• How to drive two types of motors with different
settings.
• How to retain the settings for two types of motors
separately.
• How to change the settings all together for a batch
production.
• This function changes the valid parameters by
assigning 024[SET] to the input terminal function
and turning it on. In conjunction with [SET], the
output terminal 012[SETM] is turned on.
• The following is the notation for the parameters that
are changed with the [SET] terminal.
Example of the Common Settings
Parameters
• The [SET] terminal can be switched while the
output of the inverter is blocked. If it is being
switched during the output, it is switched after the
output blockage.
• Even if you want to switch the [SET] terminal for
immediate operation, take more than 1 s for the
switching time.
Example of the First Setting
Example of the Second Setting
Example) SET Function Type Notation Description
Common
The third digit of the parameter is "-":
[Ab-01], [bA-30], [CC-01], etc. The parameter is common to the first and second settings
regardless of the SET function. Always valid.
First setting
The third digit of the parameter is "1":
[AA101], [bC112], [Hb102], etc.
If the
[SET] terminal is off or the [SET] function is not
assigned (off), the first setting is applied. The data for
which the third digit of the parameter is "1" are all valid.
Second
setting The third digit of the parameter is "2":
[AA201], [bC212], [Hb202], etc.
If the
[SET] terminal is on, the second setting is applied.
The data for which the third digit of the parameter is "2" are
all valid.
Item Parameter Data Description

[SET]: Second setting function
OFF: The first setting is valid.
ON: The second setting is valid.
*) If the parameter does not have 024[SET] assigned, the
first setting is valid.
Output terminal
function
[CC-01]~[CC-07] 012 [SETM]: OFF when SET is OFF; ON when SET is ON.
