Linear Accelera-
tion Rate/Acceler-
ation Time
Constant
This parameter sets the acceleration rate or the
acceleration time constant based on the setting in
bits 4 through 7 in OW
03.
• When the Acceleration/Deceleration Rate Unit
Selection is set to 0 (Reference units/s
2
), this
parameter sets the acceleration rate.
Pulse unit: 1 = 1 pulse/s

mm unit: 1 = 1 reference unit/s
2
Degree unit: 1 = 1 reference unit/s

Example: When the number of digits below the
decimal point is set to 3:
mm unit: 1 = 0.001 mm/s
2
Degree unit: 1 = 0.001 deg/s
2
Inch unit: 1 = 0.001 inches/s
2
μm unit: 1= 0.001 μm/s

• When the Acceleration/Deceleration Rate Unit
Selection is set to 1 (ms), this parameter sets the
time constant from 0 to the rated speed, regard-
less of the reference unit.
