XtraDrive User Manual Chapter 5 : Parameter Settings and Functions

5.8. AB Encoders
The XtraDrive supports both square wave (A quad B) and serial (Yaskawa’s
standard) encoder types. Yaskawa serial encoders are automatically detected
by the XtraDrive 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.
Pn190.2 Setting Results
0 Yaskawa Serial Encoder
1 AB Encoder
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 you will need a battery that will 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
Set the resolution of A quad B encoder in Pn192, Pn193. Note that the value
in Pn192 should be set as the physical (optical) resolution, excluding the x4
multiplication done by the driver internally.
