Continuous Mode Speed Control
When continuous mode operation is started, pulse output will be continued
until it is stopped from the program.
Note Pulse output will stop immediately if the CPU Unit is changed to PROGRAM
mode.

Independent Mode Positioning

When independent mode operation is started, pulse output will be continued
until the specified number of pulses has been output.
1. Pulse output will stop immediately if the CPU Unit is changed to PRO-
GRAM mode.
2. The number of output pulses must be set each time output is restarted.
3. 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.
4. 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.
