The rate of increase or decrease in speed within a specified time unit is set in the following Servo Parameters.
Each parameter is set in the Servo Drive via the PCU using the PCU's Servo Parameter transfer functions
(WRITE/SAVE SERVO PARAMETER Bits).
When using a trapezoidal curve (linear acceleration/deceleration) with the initial speed set to 0 (pulses/s), the
set values for the origin search acceleration time and origin search deceleration time used in the earlier PCUs
are converted to the following settings.
Pn80A (first-step linear acceleration constant):
The origin search uses a first-step acceleration/deceleration curve, so this parameter setting is not
used.
Pn80B (second-step linear acceleration constant):
The maximum speed, initial speed, and origin search acceleration time in the axis parameters of ear-
lier PCUs are converted to the value determined from the following equation.
Pn80C (acceleration constant switching speed):
The origin search uses a first-step acceleration/deceleration curve, so this parameter is set to 0
(default setting).
Pn80D (first-step linear deceleration constant):
The origin search uses a first-step acceleration/deceleration curve, so this parameter setting is not
used.
Pn80E (second-step linear deceleration constant):
The maximum speed, initial speed, and origin search deceleration time in the axis parameters of ear-
lier PCUs are converted to the value determined from the following equation.
Pn80F (deceleration constant switching speed):
The origin search uses a first-step acceleration/deceleration curve, so this parameter is set to 0
(default setting).
