6345 3565
Data unit : 1%
Data range : 0 to 100 (0 to 100%)
Standard setting : 83 (83%)
This data is used to set the detecting range of load detecting signal 1
(LDT1A).
When the motor power reaches the setting data % or more of
maximum power, the bit of load detecting signal 1 (LDT1A) is set to
”1”.

Data unit :
Data range : 0 to 6
Standard setting : 0
Select a proper pattern from the following.
A : When the acceleration/deceleration are slowly performed by
limiting the power on acceleration/deceleration only and operation is
performed at rated power in normal rotation: (Setting data: 1 or 4)
(The function is similar to the soft start/stop.)
B : When the acceleration/deceleration are performed at the maximum
power and the power is limited in normal rotation: (Setting data: 2 or
5)
C : When a machine with different power specifications is produced
using the same motor and amplifier: (Setting data: 3 or 6)
