4 Motion Parameters
4-108
( 6 ) Acceleration/Deceleration Settings
The acceleration/deceleration can be set to either the rate of acceleration/deceleration or the time
required to reach the rated speed from 0. The parameters related to acceleration/deceleration settings
are listed in the following table.

Parameters
No. 5
Number of
Decimal Places
Set the number of digits below the decimal point in the input
reference unit. The minimum reference unit is determined by this
parameter and the Command Unit (fixed parameter 4).
Example:
Command Unit = mm, Number of Decimal Places = 3
1 reference unit = 0.001 mm
3
No. 34 Rated Speed
Set the number of rotations when the motor is rotated at the rated
speed (100% speed). Confirm the motor specifications before
setting this parameter.
3000
No. 36
Encoder
Resolution
Set the number of pulses (the value after multiplication) per motor
rotation.
Example:
For a 16-bit encoder, set 2
16 = 65536.
65536
Motion Setting
Parameters
OW††03,
bits 4 to 7 Acceleration/
Deceleration Units
Set the unit for acceleration/deceleration.
0: Reference unit/s 2
1: ms
0
OL††36
Linear
Acceleration Time
Set the rate of acceleration or acceleration time constant
according to the setting of OW††03, bits 4 to 7.
• Acceleration/Deceleration Units is set to 0 (Reference units/s 2 ),
set the rate of acceleration.
Pulse unit: 1 = 1 pulse/s 2
mm unit: 1 = 1 reference unit/s 2
deg unit: 1 = 1 reference unit/s 2
Inch unit: 1 = 1 reference unit/s 2
Example: Number of Decimal Places = 3
mm unit: 1 = 0.001 mm/s
2
deg unit: 1 = 0.001 deg/s 2
Inch unit: 1 = 0.001 inch/s 2
• When Acceleration/Deceleration Units is set to 1 (ms), set the
time constant to go from 0 to the rated speed without relation to
the reference unit.
0
OL††38
Linear
Deceleration Time
Set the rate of deceleration or deceleration time constant
according to the setting of OW††03, bits 4 to 7.
• Acceleration/Deceleration Units is 0 (Reference units/s 2 ), set
the rate of deceleration.
Pulse unit: 1 = 1 pulse/s 2
mm unit: 1 = 1 reference unit/s 2
deg unit: 1 = 1 reference unit/s 2
Inch unit: 1 = 1 reference unit/s 2
• Acceleration/Deceleration Units is 1 (ms), set the time constant
to go from the rated speed to 0 without relation to the reference
unit.
