Pn40
Command Pulse
Multiplying Setting
4
-
-
-
Set the input pulse multiplication function when
you set 0 or 2: 90° phase difference (phases A
and B) signal inputs in Command Pulse Mode
(Pn42).
● The default setting of the SS2 series is 4:
Multiply the input pulses by 4.
● The G5 series does not have the related
parameter, but it always uses 4-fold input
pulses for judgment.
* To use 2-fold or so ones, use Electronic Gear
functions (Pn008 to Pn010) for adjustment.
Pn41
Command Pulse
Rotation Direction
Switch
0
Pn006
Command Pulse
Rotation Direction
Switching Selection
0
Set the motor rotation direction for command
pulse inputs.
● In both the SS2 and the G5 series, the default
setting is 0: The motor rotates in the direction
specified by the command pulse.
Pn42
Command Pulse
Mode
1
Pn007
Command Pulse
Mode Selection
1
Set the input form of input command pulses.
● In both the SS2 and the G5 series, the default
setting is 1: Reverse pulse/forward pulse.
Pn43

Pn44
Encoder Dividing
Rate Setting
2,500
pulses/
rotation
Pn011
Encoder Dividing
Numerator
2,500
pulses/
rotation
Set the number of encoder pulses per motor
rotation to be output from the Servo Drive.
● In both the SS2 and the G5 series, the default
setting is 2,500 pulses/rotation.
Pn45
Encoder Output
Direction Switch
0
Pn012
Encoder Output
Direction Switching
Selection
0
Set the logic of the encoder pulses to be output
from the Servo Drive.
● In both the SS2 and the G5 series, the default
setting is 0: Positive logic (Phase A advance in
forward operation).
Pn46
Electronic Gear
Ratio Numerator 1
10,000
Pn008
Electronic Gear
Integer Setting
10,000
Set the electronic gear function.
● The default setting of the SS2 series is
Pn46/Pn47 = 10,000, Pn4A = 0, Pn4B = 2,500,
meaning 2,500 input pulses for one motor
rotation.
● The G5 series has two setting methods.
• Using Electronic Gear Integer Setting
(Pn008)
Use Electronic Gear Integer Setting
(Pn008) to set the number of input pulses for
one motor rotation. The default setting is
10,000, meaning 10,000 input pulses for one
motor rotation.
* If you set 2,500, it will become the same as
the default setting of the SS2.
• Using Electronic Gear Ratio Numerator 1/2
(Pn009/Pn500) and Electronic Gear Ratio
Denominator (Pn010)
When you set 0 to Electronic Gear Integer
Setting (Pn008), the settings of Pn009,
Pn500, and Pn010 will be enabled.
* If 0 is set to Electronic Gear Ratio
Numerator 1/2 (Pn009/Pn500), the
resolution of the motor in use will be set
automatically to the electronic gear
numerator.
* The G5 series does not have the
Electronic Gear Ratio Numerator
Exponent parameter.

Filter Time Constant
0.0
ms
Set the first-order lag filter time constant in the
command pulse input section.
● In both the SS2 and the G5 series, the default
setting is 0.0 ms.
● Be careful in setting because the setting unit is
different.
