Description
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.
Pn50F
Selection function
0300
Set it when servo motor with brakes.
Bit 2: Set 3, brake 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.
Pn506
Servo off, time
delay of brake
when motor stops
Depended
Set it when motor with brakes
Default setting is “0”, setting unit is 10ms.

Pn202 = pulse No. of each encoder circle × 4 ×
mechanical deceleration ratio.
Pn203 = (lead screw pitch/ pulse equivalent).
Typical value: pitch 5mm, encoder 17-bit, coaxial
connection between motor and screw, pulse equivalent
0.001mm, Pn202＝16384; Pn203＝625.
Pitch 5mm, encoder 17-bit, coaxial connection
between motor and screw, pulse equivalent 0.0005mm,
Pn202＝8192; Pn203＝625.
