Secondary Encoder
Some application requires an external encoder (secondary encoder).
To be able to use secondary encoder device - Differential A/B encoder only - user have to connect is to C3 interface in the CDHD:
Activate
To activate secondary encoder function it's necessary to set drive GEARMODE to 3 (and SAVE this setting) using ServoStudio
 | NOTE |
| The external position is monitored by the drive in all operation modes - position, velocity and torque |
When secondary encoder is active, one can read it's position through EtherCAT object 0x20B6 sub-index 0.
By mapping this object to PDO (using softMC Configurator) encoder position can be monitored using <axis>.pext command.
Example
In this example we assume that axis 1 has external encoder connected to it's CDHD drive
This simple example print each second axis position according to the secondary encoder:
program continue
while 1
call axisExternalPos
sleep 1000
end program
public sub axisExternalPos
print "a1 external position is: " + str$(a1.pext)
end sub
