Function block Description
Function 1
(U04 etc.)
Function 2
(U05 etc.)
6002 Writing function
codes
This function writes the value of input 1 to a function
code (U171 to U175) on the volatile memory (RAM)
when the input 2 becomes “1: True”. When the input 2
becomes “0: False”, this function stops to write to the
function code (U171 to U175) and maintains the
previous value. The value of input 1 is stored to the
non-volatile memory (EEPROM) when the inverter
detects undervoltage.
Because the access arbitration from some steps at a
time is not possible, only one step is allowed to
access to the same function code in the customizable
logic. If the access to the target function code from
different steps at a time is executed, the alarm is
displayed.

6003 Temporary
change of
function code
This function reflects the value of the specified
function code on the volatile memory (RAM) when the
input 2 becomes “0: False”. On the other hand when
the input 2 does not become “0: False”, this function
reflects the value of input 1 in the place of the
The value on the volatile memory (RAM) is cleared
when the inverter is powered off.
And the value is read from the non-volatile memory
and restored when the inverter is powered on.
Set the function code group (function type code) to
the1st function code (U04, etc.).
Set the lower 2 digits of the function code No. to the
2nd function (U05, etc.).
If the specified function code (U04, U05, etc.) is not
applicable one, this function outputs zero value.
Because the access arbitration from some steps at a
time is not possible, only one step is allowed with to
access to the same function code in the customizable
logic.
When the function code is temporarily changed using
6003 during the customize logic operation and if the
PC loader is read or copy to the touch panel is
performed, the temporary changed data, not the
non-volatile memory data, may be copied.
Stop the customize logic before these operations.

6101 PID dancer
output gain
frequency
Circuit to switch either to calculate a frequency
correction where 100% of PID output shall be the
maximum frequency, or to calculate a frequency
correction proportional to the line speed command.
Use the input 1 to switch this circuit. Use the input 2
and gain ratio (1st function code) to set the frequency
correction.
Output: Frequency correction = (PID output) × (Line
speed command) ••• (Input 2 OFF, U04≠0%)
Frequency correction amount = (PID output×Gain
ratio (U04)) × (Maximum output frequency) ••• (Input
2 ON, U04 ≠ 0%) Note that when the gain ratio is set
to 0%, the following applies regardless of the input 2:
