Conjunction with the System
12.17.1 Using by Switching between Two
Settings
Q
• 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.
A
• 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.

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

• 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.

Description
The parameter is common to the first and second settings
regardless of the SET function. Always valid.
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.
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.
