Error Counter Overflow
Detection Value
Setting
Error counter If the absolute value of the
overflow detection error counter present value is
value greater than the error counter
overflow detection value, the
Error Counter Error Flag
(A26.03) will turn ON.
Error Counter Alarm
Detection Value
Setting
Error counter If the absolute value of the
alarm detection error counter present value is
value greater than the error counter
alarm detection value, the
Error Counter Alarm Flag
(A26.08) will turn ON.

Error Counter Cycle

Setting
Error counter The calculation cycle of the error
cycle 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.
Power Supply Frequency
for One Motor Revolution
per Second
Setting
Power Supply Calculate the power supply fre-
Freq. for One quency for one revolution per second
Motor Revolution from the motor specifications. For
per Sec. 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.
Default
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.
