Description
Fn010
Parameter input
prohibition setting
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.
Pn000
Function selection
basic switch 0
0010
Bit 0: Set 0, positive rotation at positive rotation
command; Bit 1: Set 1, position control mode (pulse
sequence command)
Pn200
Format selection
switch of position
control command
0005
Bit 0: Set 5, select the instruc
tion mode as “pulse +
direction”, negative logic; Bit3: Set 0, input differential
signal into filter.
Pn50A
Input signal
selection 1
8100
Bit 1: Set 0, Servo ON /S-ON, input from the 40th pin;
Set 7, Servo ON all the time; Bit 3: Set 8, positive
rotation not used and signal input (P-OT) prohibited.
Pn50B
Input signal
selection 2
6548
Bit 0: Set 8, negative rotation not used and signal
input (N-OT) prohibited.
Pn50F
Output signal
selection 2
0300
Set it when servo motor with brakes.
Bit 2: Set 3, brake in
terlock signal “/BK” is output from
CN1-29, CN1-30 to control 24V relay used for brake
Pn50E
Output signal
selection 1
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
Brake instruction-
servo OFF and
time delay
Depended
Set it when motor with brakes
Default setting is “0”, setting unit is ms.
Pn20E
Electronic gear
ratio (numerator)
Need
Calculation
Pn20E = pulse No. of each encoder circle × 4 ×
mechanical deceleration ratio.
Pn210 = (lead screw pitch/ pulse equivalent).
Both numerator and denominator of electronic gear
ratio can be reduced, they are integers within
“1~65536”. Typical value: pitch 5mm, encoder 17-bit,
shaft coupler direct drag, pulse equivalent 0.001mm,
Pn20E
＝
16384; Pn210
＝
625.
Pitch 5mm, encoder 17-bit, shaft coupler direct drag,
pulse equivalent 0.0005mm, Pn20E
＝
8192; Pn210
＝
