6.2 Various Functions

ME0384-4A
(2) Control with function enabled
1) The same process as the existing complete stop function will be performed until the
energization amount reaches current limit during positioning stop (parameter).
2) After completion of current energization during stop, the state is maintained until target
position deviation does not occur (zero).
3) In accordance with whether target deviation is present or not, the energization amount will be
manipulated.
• Without target position deviation, energization decreases by a fixed amount
• With target position deviation, energization increases by a fixed amount
The following restrictions are applicable for the manipulation of the energization amount.
· Decrease in energization amount ⇒ When process transition of increase is performed more
than a set number of times, only increase process will be executed.
· Minimum energization amount is defined per actuator basis, and without position deviation, it
allows energization amount to increase to the applicable amount.
· Maximum energization amount is current limit value during positioning stop (parameter), and
allows energization amount to increase to the applicable amount.
(3) Precautions
1) Difference in target position deviation depending on the encoder resolution
For actuator with lead length 24 [mm/r]
■ If the encoder resolution is 800 [pulse/r], it allows the energization amount to decrease until
target position deviation of 24÷800 = 0.0300 [mm] is generated.
■ If the encoder resolution is 8,192 [pulse/r], it allows the energization amount to decrease
until target position deviation of 24÷8,192 = 0.0029... [mm] is generated.
2) Precautions for high-resolution encoder
For an actuator with built-in high resolution encoder, when positioning complete status
continues for an extended period of time, even if this function is enabled, the energization
amount will eventually rise to current limit value during positioning stop (parameter).
