Operation Purpose Application
Stopping Stop pulse Immediate stop
pulse output output
Stop pulse Immediate stop
output
Independent Mode Positioning
When independent mode operation is started, pulse output will be continued until the specified number
of pulses has been output.
Note • Pulse output will stop immediately if the CPU Unit is changed to PROGRAM mode.
• The number of output pulses must be set each time output is restarted.
• The number of output pulses must be set in advance with PULS(881). Pulses will not be output for
SPED(885) if PULS(881) is not executed first.
• The direction set in the SPED(885) operand will be ignored if the number of pulses is set with PULS(881)
as an absolute value.
Operation Purpose Application
Starting To output with Positioning
pulse output specified without accel-
speed eration or
deceleration
Changing To change Changing the
settings speed in one speed in one
step step during
operation

Note The target posi-
tion (number of
pulses) cannot be
