3.6.2 Parameter Setting of YASKAWA Σ-Ⅱ Servo Driver
LXXXX
(Hexadecimal
system)
Monitor if the number of sent and received pulse is
correct by setting this parameter. In Weihong
control system, the correct quantity of pulse sent by
control card is detected by pulse inspection in order
to determine whether there is electrical
interference.

Bit 0: Set 0, “CCW” is forward rotation (viewed from
the load end of screw ball); Set 1, the rotation
direction of the motor is reversed.
Bit 1: Set 1, position control mode (calculate pulse
instruction all the time).
Selection servo
off or alarm stop
mode
Bit 0: Set ”0”, stopping the motor by applying
dynamic brake(DB) which will be maintained after
stop;
Set ”1”, stopping the motor by applying dynamic
brake(DB) and then motor can rotate freely after
stop.
Bit 0: Set “5”, select instruction mode as “pulse +
direction”, negative logic.
Bit3: Set “0”, input differential signal into filter.
