Communication via group 90 and group 92
The other possibility is to connect via group 90 and group 92. Again, the 3
rd
data word from overriding control
to drive should be the torque reference and the 3
rd
data word from the drive to the overriding control should be
the actual motor torque. Therefore, following settings have to be made (values see table below):
− PZD3 OUT (51.05) = 3 and
− PZD3 IN (51.06) = 6.
After changing parameters in group 51 please do not forget to reset the RPBA-01 adapter by means of FBA
PAR REFRESH (51.27) = RESET. Now the corresponding parameters in group 90 and group 92 are enabled.
Following settings have to be made now:
− DsetXVal3 (90.03) = 2501 [TorqRefA (25.01)] and
− DsetXplus1Val3 (92.03) = 107 [MotTorqFilt (1.07)].
