Note The following examples are for Fujitsu-compatible connectors. Output bit ad-
dresses and connector pin numbers depend on the models. Refer to the CPM2C
Operation Manual (W356) or the CPM2C-S Operation Manual (W377) for de-
tails.
01000: Pulse output 0 (single-phase output)
01001: Pulse output 1 (single-phase output)
Make the following settings in the PC Setup.

Synchronized pulse control cannot be used simultaneously.
The settings will go into effect when the mode is changed (from PROGRAM to
MONITOR/RUN) or when the power supply is turned ON to the PC.
The following table shows the instruction operations related to pulse outputs
with variable duty ratio.

The following table shows which instructions can be executed during pulse out-
puts without acceleration and deceleration.

Note 1. This instruction can be used only for stopping pulse outputs.
2. This instruction can be used only for changing the duty ratio. The frequency
cannot be changed while pulses are being output. If the frequency needs to
be changed, be sure to stop the pulse output first.
