04 T16 scale Defines the reference multiplier/actual 
value divisor for the adapter module. The 
parameter is effective only when the 
Transparent 16 profile is selected AND the 
drive is using the native communication 
profile (eg, DCU or FBA) and a 16-bit 
transparent Reference 1/Actual value 1.
With an ACS355 drive, the speed reference
from the PLC is multiplied by the value of 
this parameter plus one. For example, if the
parameter has a value of 99 and a 
reference of 1000 given by the master, the 
reference will be multiplied by 99 + 1 = 100 
and forwarded to the drive as 100000. 
According to the DCU profile, this value is 
interpreted as a reference of 100 rpm in the 
drive.
With ACSM1, ACS850, ACQ810 and 
ACS880, setting this parameter to 65535 
provides the approximation of 1 = 1 rpm.

05 X1 MDI/MDIX Defines the cable type connected to the 
port.
The auto MDI/MDIX detection feature is 
enabled by default. For each port, you can 
disable auto MDI/MDIX and designate the 
port as MDI port or designate the port as 
MDIX port. 
Connect MDI port to MDIX port via straight-
through twisted pair cabling. Both MDI-to-
MDI and MDIX-to-MDIX connections use 
crossover twisted pair cabling.
0 = Auto
0 = Auto Auto detect.
1 = MDI Designates the port as MDI port.
2 = MDIX Designates the port as MDIX port.
