6.3.1 ODVA I/O Assembly instances for AC/DC Drive
The Vacon 100 drive supports the Output Assembly Instances 20, 21 and 23, and the Input
Assembly Instances 70, 71 and 73.
6.3.1.1 Output Assembly Instance 20
The contents of the assembly are defined as follows:
• Bits 7-3 and bit 1 in the first octet of the assembly are reserved, and always have the value 0.
• Bit 2 in the first octet of the assembly is “Fault Reset”, which is mapped to the “FaultRst”
attribute (Attribute ID = 12
d) in the Control Supervisor Object (Class number 29h). See
Instance Attribute “FaultRst”.
• Bit 0 in the first octet of the assembly is “Run Fwd”, which is mapped to the “Run1” attribute
(Attribute ID = 3
d) in the Control Supervisor Object (Class number 29h). See Instance Attri-
bute “Run1”.
• The second octet of the assembly is reserved and always has the value 0.
• The third octet of the assembly is the low-octet of “Speed Reference”, while the fourth octet
is the high-octet of “Speed Reference”. The combined 16-bit reference of these fields is
mapped to the “SpeedRef” attribute (Attribute ID = 8
d) in the AC/DC Drive Object (Class num-
ber 2A
h). See Instance Attribute “SpeedRef”.
