Changing to CS1W/CJ1W-NC271/471/F71 from CS1W/CJ1W-NC113/133/213/233/413/433
Appendix E
Pn80C (acceleration constant switching speed):
The operation uses a first-step acceleration/deceleration curve, so this parameter is set to 0 (default
setting).
Pn80D (first-step linear deceleration constant):
The operation uses a first-step acceleration/deceleration curve, so this parameter setting is not used.
Pn80E (second-step linear deceleration constant):
The maximum speed and initial speed in the axis parameters and the deceleration time in the Oper-
ating Data Area of earlier PCUs are converted to the value determined from the following equation.
Pn80F (deceleration constant switching speed):
The operation uses a first-step acceleration/deceleration curve, so this parameter is set to 0 (default
setting).
Changing Target Position and Changing Target Speed
The target position and target speed can be changed during axis operation in the same way for both earlier
PCUs and the CS1W/CJ1W-NC271/471/F71 PCU by using the following operation.
Changing target position:Set the new target position in Position Command Value and send an operation
command again. (Strictly speaking, the new target position is to be set in Posi-
tion of the Operating Data Area for earlier PCUs while it is set in Position Com-
mand Value in the Axis Operating Output Memory Area for CS1W/CJ1W-
NC271/471/F71 PCUs.)
Changing target speed: Change Speed Command Value during axis operation to immediately change
the target speed. (Strictly speaking, the new target speed is to be set in Speed
of the Operating Data Area for earlier PCUs while it is set in Speed Command
Value in the Axis Operating Output Memory Area for CS1W/CJ1W-
NC271/471/F71 PCUs.)
When changing the target position with a CS1W/CJ1W-NC271/471/F71 PCU, however, the Receiving Com-
mand Flag must be used to control the ON/OFF timing for the operation command bits.
