[Tune mode]
Acceleration time constant (speed mode)
● Function
[Acceleration time constant] is the time it takes to
accelerate the motor from [0 r/min] to the speed of [A:
speed limit] of [parameter mode].
The acceleration time to speed command voltage is as
follows:
● Details of display
1st digit: [7: Acceleration time constant]
2nd to 3rd digit: No indication
4th to 6th digit: Indicates current [Acceleration time
constant], unit and a value from [0] to [9999]
ms can be set.
● 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) To make [acceleration time constant] low, press the [DOWN] key to set a lower value.
To make it higher, press the [UP] key to set a higher value.
(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.

Deceleration time constant (speed mode)
● Function
[Deceleration time constant] is the time it takes to
decelerate the motor from the speed of [A: speed limit] of
[parameter mode] to [0 r/min]. The deceleration time to
speed command voltage is as follows:
● Details of display
1st digit: [8: Deceleration time constant]
2nd to 3rd digit: No indication
4th to 6th digit: Indicates current [Deceleration time
constant], unit and a value from [0] to [9999]
ms can be set.
