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
Surveillance
mode
LXXXX
(Hexadeci-
mal
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‖ rotation 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).

Bit 1: Set 0, Servo ON /S-ON, input from the 40th pin;
Set 7, Servo ON all the time.
Bit 3: Set 8, forward rotation not used and signal input
(P-OT) prohibited.
Pn50B
Selection

Bit 0: Set 8, reverse rotation not used and signal input
(N-OT) prohibited.
Pn50F
Selection
function
0300
Set it when servo motor with brakes.
Bit 2: Set 3, b
rake interlock signal ―/BK‖ is output from
CN1-29, CN1-30 to control 24V relay for brake.
Pn50E
Selection
function
0211
Set it when servo motor with brakes.
To avoid of CN1-29 and CN1-30 being used for other
function and leading to brake ineffective, ―3‖ is not
allowed to appear in the 4 digits.

Pn202 = pulse No. of each encoder circle × 4 ×
mechanical deceleration ratio.
Pn203 = (screw pitch/ pulse equivalent).
