13.5.6.3.7 OB 1 - Create instance of the V1000 initialization
The FB 881 - VMC_InitV1000_RTU initializes the corresponding inverter drive with the
user data. Before an inverter drive can be controlled, it must be initialized.
1. Add a Call FB881, DB881 to OB 1.
ð
The block call is created and a dialog opens to specify the instance data block
‘VMC_InitV1000_RTU _881’ .
2. Confirm the query of the instance data block with [OK].
3. Specify the following parameters:
Call FB881, DB881

All parameters must be interconnected with the corresponding variables or operands. The
following input parameters must be pre-assigned:
n Hardware
Here specify the hardware you use to control your inverter drives:
– 1: System SLIO CP040 whose logical address is to be specified via Laddr.
– 2: SPEED7 CPU
n Laddr
– Logical address for the System SLIO CP040 (Hardware = 1). Otherwise, this
parameter is ignored.
n UnitId
– Modbus address of the V1000.
