7.2. Using Gain Adjustment Values for SS2 Series as Those for G5 Series
It is possible to modify the gain adjustment values for SS2 series that had been used, so as to use them as those for G5
series.
The following table shows the four basic parameters related to gain adjustment.
According to
SS2 to G5 settings
, modify the gain adjustment values for SS2 series into those for G5 series.
* The G5 series has higher control performance, so it provides higher-speed and higher-precision operation as compared with
the SS2 series.
If possible, you are recommended to use the auto tuning function to set them again, after replacement with the G5 series.

Pn10
Position Loop Gain

Pn100 Position Loop Gain
48.0/32.
0 s

*1
Set the proportional gain of position
control.
In setting, pay attention to the units, 1
s
-1
for the SS2 series and 0.1 s
-1
for the
G5 series.
Pn11
Speed Loop Gain
60 Hz
Pn101 Speed Loop Gain
27.0/18.
0 Hz*1
Set the proportional gain of speed
control.
In setting, pay attention to the units, 1
Hz for the SS2 series and 0.1 Hz for
the G5 series.
Pn12
Speed Loop
Integration Time
Constant
20 ms
Pn102
Speed Loop Integral
Time Constant
21.0/31.
0 ms*1
Set the integration time constant of
speed control.
In setting, pay attention to the units, 1
ms for the SS2 series and 0.1 ms for
the G5 series.
Pn14
Torque Command
Filter Time Constant
1.00 ms
Pn104
Torque Command
Filter Time Constant
0.84/1.2
6 ms*1
Set the torque command filter time
constant of torque control. Set the
value as it is, because the unit remains
unchanged.
*1. For the numerical notation sv/SV, sv represents the setting for less than 1 kW drives of 100 V or 200 V type, and SV
represents the setting for other drives.
