9-3-1. Continuous operation using a pulsar input (MOD: 01h)
This mode allows continuous operation using a pulsar input.
When PA/PB signals are input after writing a start command, the LSI will output pulses to the OUT
terminal.
The
feed direction depends on PA/PB signal input method and the value set in PDIR.

The PCL stops operation when the EL signal in the current feed direction is turned ON. But the PCL can
be operated in the opposite direction without writing a restart command.
When stopped by the EL input, no error interrupt ( output) will occur.
To release the operation mode, write an immediate stop command (49h).
9-3-2. Positioning operations using a pulsar input (MOD: 51h)
The PCL positioning is synchronized with the pulsar input by using the PRMV setting as incremental
position data.
When starting an axis, the PCL loads the RMV register value into the positioning counter.
The feed direction is determined by the sign in the PRMV register.
When PA/PB signals are input, the LSI outputs pulses and the positioning counter counts down. When the
value in the positioning counter reaches zero, movement on the axis will stop and another PA/ PB input
will be ignored. Set the PRMV register value to zero and start the positioning operation. The LSI will stop
movement on the axis immediately, without outputting any command pulses.
