Table 1 Setting up communication
After the communication initialization parameters have been set, the drive control
parameters must be checked and adjusted where necessary.
In an Optical ModuleBus connection, channel 0 address (parameter 70.01) is
calculated from the value of the POSITION terminal in the appropriate database
element (for the AC 80, DRISTD) as follows:
1. Multiply the hundreds of the value of POSITION by 16.
2. Add the tens and ones of the value of POSITION to the result.
For example, if the POSITION terminal of the DRISTD database element has the
value of 110 (the tenth drive on the Optical ModuleBus ring), parameter 70.01 must
be set to 16 × 1 + 10 = 26.
