5.8. AB Encoders
The FSP Amplifier supports both square wave (A quad B) and serial (Yaskawa’s
standard) encoder types. Yaskawa serial encoders are automatically detected by
the FSP Amplifier and require no additional settings (please refer to chapter 5.7
for detailed information). In applications where standard A quad B encoders are
used, certain parameters related to the motor and characteristics must be set
manually. The following parameters should be set according to the specific
encoder manually. Please note that these parameters become active only after
restarting the driver.
Note: There are some parameters related to the motor electro-mechanical
characteristics that cannot be set by the user. Contact the manufacturer in order to
get a setup file containing these parameters.
First set the AB encoder by Pn190.2 to 1, 2, or 3, depending on your motor.
Pn190.2 Setting Results
0 Yaskawa Serial Encoder
1 AB Encoder, Software commutation
2 AB Encoder, Commutation sensors positive (U,V,W)
3 AB Encoder, Commutation sensors negative (/U, /V, /W)
Set Pn190.0 according to the following table:
Pn190.0 Setting Results
0 Yaskawa AB model SGM
1 Yaskawa AB model SGMP
2 Other motor brand with A quad B encoder
Absolute/Incremental encoder. Set the following parameter to choose between an
absolute encoder and an incremental encoder.
Pn190.1 Setting Results
0 Incremental Encoder
1 Yaskawa absolute A quad B encoder
To use the absolute encoder properly a battery will be needed to power the
encoder memory to keep its position.
C-pulse – Set the following parameter to choose between motor with and without
C-pulse.
Pn190.3 Setting Results
0 C-pulse used
1 C-pulse not used
