Multiturn limit setting is a parameter to set the upper limit of multi-turn data from
encoder when absolute encoder is used (P01-12 = ENC-R). When the rotation amount
exceeds the set value, the encoder rotation amount returns to zero. The range of multi-
turn data differs from the factory settings and other settings.

P02-34 Setting value
Other than the factory setting (≠ 65535) When the motor rotates in the reverse direction
from the multi-rotation data 0, the multi-turn data changes to the setting value of P02-
34. When the multi-turn data rotates in the forward direction at the setting value of P02-
34, the multi-turn data changes to zero. For P02-34, set the value of (Multiple desired
rotation-1).
* Changing the multiturn limit is not necessary except for special applications. This
parameter is related to the host controller, so special care should be taken.

When using absolute encoder, the battery voltage drop (3.1 ± 0.1 [V] or less) can be

This parameter sets the filter time constant for abnormal alarm occurrence due to noise
signal or cable mounting condition when using absolute encoder. The larger the value is
selected, the less sensitive the battery alarm is caused by the noisy signal.
