Setting
Description
Set value
Default
Application
Refresh timing
Error counter
overflow detection
value
If the absolute value of the
error counter present value is
greater than the error counter
overflow detection value, the
Error Counter Error Flag
(A26.03) will turn ON.
1 to 32,767
Setting 0 is
the same as
setting
10,000.
0: 10,000
Provides notification of
excessive pulses in the
error counter, e.g., when
manually moving the
motor shaft while position-
ing is stopped.

If the absolute value of the

alarm detection value, the
Error Counter Alarm Flag
(A26.08) will turn ON.
1 to 32,767
Setting 0 is
the same as
setting
10,000.
0: 10,000
Provides notification of
excessive pulses in the
error counter, e.g., when
encoder wiring breaks dur-
ing positioning.

Application
Refresh timing
Error counter
cycle
The calculation cycle of the error
counter can be set. If the cycle is
too short when using a motor with a
slow response, pulses may easily
accumulate in the error counter.
Change the error counter cycle
according to the machine load and
motor response.
Note
The setting is made in incre-
ments of 4 ms. The error
counter cycle will thus be the
set value times 4 ms. For
example, if the set value is
10, the error counter cycle
will be 40 ms.
1 to 255 (in 4-
ms increments)
Setting 0 is the
same as setting
3 (4-ms incre-
ments)
0: 3 (4-ms
incre-
ments)
The error
counter
cycle will
be 12 ms.
Set when using
a motor with a
slow response.

Power Supply
Freq. for One
Motor Revolution
per Sec.
Calculate the power supply fre-
quency for one revolution per second
from the motor specifications. For
example, with a 1,800-r/min (60-Hz)
motor (30 r/s), the power supply fre-
quency for one revolution per second
would be calculated as follows:
60 [Hz]
÷
30 [r/s] = 2 [Hz].
Note
The setting is made in incre-
ments of 0.1 Hz. The fre-
quency will thus be the set
value times 0.1 Hz. For exam-
ple, if the set value is 20, the
frequency will be 2 Hz.
0 to 65,535 Hz
(0.1-Hz incre-
ments)
0 (0.1-Hz
incre-
ments)
This setting is
used when con-
verting the out-
put value to an
inverter fre-
quency com-
mand.
