30 POSITIONING PARAMETER
30.2 Details of Parameters
■SIGN/CCW
SIGN output in PULSE/SIGN mode or CCW output in CW/CCW mode is selected.
For the CW/CCW mode, this parameter does not need to be set for CCW because the axis number and output device (Y) that
executes outputs are fixed.
Rotation Direction Setting
Setting method: High Speed I/O Parameter, Special Device
Set the relationship between motor rotation direction and increase or decrease of the current address.
■High Speed I/O Parameter
When [0: Current Address Increment with Forward Run Pulse Output] is selected, the current address increases when
forward pulses are output and decreases when reverse pulses are output.
When [1: Current Address Increment with Reverse Run Pulse Output] is selected, the current address increases when
reverse pulses are output and decreases when forward pulses are output.
■Special Device
When rotation direction setting is turned off: The current address increases when forward pulses are output and decreases
when reverse pulses are output.
When rotation direction setting is turned on: the current address increases when reverse pulses are output and decreases
when forward pulses are output.
For the PLSV/DPLSV instruction and table operation instruction (control method: [4: Variable Speed
Operation] or [5: Table Transition Variable Speed Operation]), the direction of increase/decrease in the
address and pulse output direction are determined by the sign of the command speed and rotation direction
setting, as shown below.
For the DSZR/DDSZR instruction, the direction of increase/decrease in the address and the pulse output
direction are determined by the OPR direction and rotation direction setting. (Page 436 OPR direction)
