[Parameter mode]
Position error allowance (position mode)
● Function
The [error counter] calculates [error count] subtracting the
[feedback count] from the [position command]. A large
position error may result in an abnormality.
When the position error exceeds the [position error
allowance], an [alarm 60] occurs and the servo power
shuts off.
● Details of display
1st digit: [6: position error allowance]
2nd digit: No indication
3rd to 6th digit: Indicates the current [position error
allowance]. A value from [1] to [1000] can be
set.
● Operations
(1) To change a value, press the [ADJ] key at least 0.1
second.
⇒1st digit [6] flashes. You can change the value.
(2) To make the allowance narrow, press the [DOWN]
key.
To make it wide, press the [UP] key.
(3) To define the new value, press the [SET] key at least 0.1 second.
⇒ Flashing of 1st digit [6] stops and the new value is defined.
(4) To cancel a change in operation, press the [ADJ] key at least 0.1 second.
⇒Flashing of 1st digit [6] stops and the previous value becomes effective.
Zero clamp (speed mode)
● Function
In the speed mode when the [speed command] is [0], the
actuator may rotate slightly by force from the drive
mechanism. The [Zero clamp] function forcefully stops
actuator when the speed command is [0].
● Details of display
1st digit: [7: Zero clamp]
2nd to 5th digit: No indication
6th digit: Indicates current setting of [zero clamp]
function.
[0]: Zero clamp OFF; [1]: Zero clamp ON
● Operations
(1) To change a value, press the [ADJ] key at least 0.1
second.
⇒1st digit [7] flashes. You can change the value.
(2) By the keys of [UP] and [DOWN], set [0] (no function)
or [1] (zero clamp).
(3) To define the new value, press the [SET] key at least 0.1 second.
⇒ Flashing of 1st digit [7] stops and the new value is defined.
(4) To cancel a change in operation, press the [ADJ] key at least 0.1 second.
⇒Flashing of 1st digit [7] stops and the previous value becomes effective.
