5-8 Programmable analog output function (PAO)

5-8-1 Types of analog outputs

As a standard, there are two programmable analog outputs (10 bits) in the VAT2000, with terminal board
numbers FM-COM, and AM-COM. Two more analog outputs are available by the optional PCB
U2KV23TR0 (Trace Back option).
Each output can be programmed with the internal functions shown in Fig. 5-8. As default, FM is assigned
as "output frequency" and AM is assigned as "Motor output current".

5-8-2 Setting the analog output

The following internal data or functions can be output to FM, AM terminals by parameters C13-0 and C13-
1 as shown in Fig. 5-8.
The extended analog outputs AO1 and AO2, can be addressed with the internal data by parameters C39-
0 and C39-1.
If needed, the gain of analog outputs can be adjusted by parameters C14-0, C14-1.
