3. Implementation of the communication option cards
3. 8. Communication via Modbus Plus network
3. 8. 1. Reminder of the possible connection methods: Same as existing
3. 8. 2. Configuring the drive address on the Modbus Plus network
On the Altivar 38’s Modbus Plus option card, the drive address is coded using switches 1 to 6 (LSB to MSB).
Therefore, simply transfer the switch configuration of a Modbus Plus option card for Altivar 38 to the switches of a Modbus Plus option card
for Altivar 61.
The address corresponds to the binary number given by position 0 or 1 of the 6 switches increased by 1.
E.g., address 6 = 5 (+1)
3. 8. 3. Configuring the drive in "ATV38 Interchangeability" mode
In order to use the Altivar 38 Peer Cop and Global Data variables rather than those of the Altivar 61, you need to set the right-hand switch
to the ON position and restart the drive.
• Switch 0 (OFF): Altivar 61 mode
• Switch 1 (ON): 8 serie mode
1 = GND
2 = Tx
3 = Rx
