7.2. Driver Parameters and Wiring Diagrams
7.2.1. Driver parameters
Driver parameters listed in this chapter can only make a machine tool motion normally, not perfectly. To
get a better machining result, you need to read through the servo driver documentation of the
corresponding brand and change the parameter setting according to the specific machine tool.

Description
Fn010
Set password (to
prevent arbitrarily
modification to
parameters)
0000
Set [0000]:
modification to user parameters [PnXXX] and part
of auxiliary function parameters [FnXXX] permitted;
Set [0001]:
modification to user parameters [PnXXX] and part
of auxiliary function parameters [FnXXX] prohibited.
Un00C
Pulse counter of
input command
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.
Pn000
Direction selection
Control mode
selection
0010
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).
Pn200
Select pulse
instruction mode
0005
Bit 0: Set 5, select the instruction input mode as
pulse + direction, negative logic.
Bit 3: Set 0, input differential signal into filter.
Pn50A
Selection function
8100
Bit 1: Set 0, Servo ON /S-ON, input from 40th pin;
Set 7, Servo ON all the time.
Bit 3: Set 8, positive rotation not used and signal
input (P-OT) prohibited.
Pn50B
Selection function
6548
Bit 0: Set 8, reverse rotation not used and signal
input (N-OT) prohibited.
