Acceleration/Deceleration Settings - YASKAWA JEPMC-MP2300-Y Series User Manual

6.5.6 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 settings method used depends on the related parameter
settings.
The parameters related to acceleration/deceleration settings are listed in the following table.

6.5 Example of Setting Motion Parameters for the Machine
Description
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
Set the number of rotations when the motor is rotated at the
rated speed (100% speed). Confirm the motor specifications
before setting this parameter.
Set the number of pulses (the value after multiplication) per
motor rotation.
Example:
16
For a 16-bit encoder, set 2 = 65536.
Set the unit for acceleration/deceleration.
2
0: Reference units/s
1: ms
Set the rate of acceleration or acceleration time constant
according to the setting of OW
• Acceleration/Deceleration Units is set to 0 (Reference
2
units/s ), set the rate of acceleration.
2
Pulse unit: 1 = 1 pulse/s
mm unit: 1 = 1 reference unit/s
deg unit: 1 = 1 reference unit/s
Inch unit: 1 = 1 reference unit/s
Example: Number of Decimal Places = 3
2
mm unit: 1 = 0.001 mm/s
2
deg unit: 1 = 0.001 deg/s
2
Inch unit: 1 = 0.001 inch/s
• 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.
Set the rate of deceleration or deceleration time constant
according to the setting of OW
• Acceleration/Deceleration Units is set to 0 (Reference
2
units/s ),
set the rate of deceleration.
2
Pulse unit: 1 = 1 pulse/s
mm unit: 1 = 1 reference unit/s
deg unit: 1 = 1 reference unit/s
Inch unit: 1 = 1 reference unit/s
• 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.
