Pulse Outputs

Section 7-6

Setting the
Speed-change Cycle

The speed change cycle for the ACC(888) and PLS2(887) instructions is
specified by setting the ON/OFF bit status of A628.07 before executing the
ACC(888) or PLS2(887) instruction.

2-ms Cycle

Execute ACC(888) or PLS2(887) with A628.07 OFF.

1-ms Cycle

Execute ACC(888) or PLS2(887) with A628.07 ON.

7-6-12 PLS2(887) Pulse Output Direction Priority Mode

The direction of pulses output by the PLS2(887) instruction can be deter-
mined manually based on a user-set operand (pulse output direction priority
mode) or automatically based on the absolute position (absolute position pri-
ority mode).

Pulse Output Direction
Priority Mode

The user determines the pulse output direction with an operand setting.

Pulses will be output only when the output direction specified in the
PLS2(887) instruction matches the direction determined from the absolute
position.

Absolute Position Priority
Mode

The pulse output direction is determined automatically from the absolute posi-
tion.

The Motion Control Module ignores the pulse output direction specified by the
PLS2(887) operand setting. This mode allows positioning to be based on the
absolute position only, so it is not necessary for the user to specify the direc-
tion.
