AC30 series Variable Speed Inverter
Inverter Configuration
Enabling
To enable the PROFINET IO device set the parameter 3132 PROFINET Enable to TRUE . Note the PROFINET IO device will only operate when
the inverter is the Operational state.
The current state of the PROFINET IO device is given by the parameter 3143 PROFINET State .
Station Name
A station name must be assigned to the PROFINET device. This is set using a PROFINET configuration program. Typically this is done from
within the PC program used to program the PROFINET PLC. The station name is stored in non-volatile memory within the inverter.
The station name should consist of only alpha-numeric, period (.) and hyphen (-) characters. The diagnostic parameter 3136 PROFINET Station
Name shows the first 21 characters of the station name.
Update Time
The cyclic I/O update time is set by the PLC. Update times allowed are calculated by multiples (8, 16, …, 512) of the send clock (1ms). Thus the
lowest update time is
8ms . However due to constraints in the inverter the update time is further restricted by the switching frequency, as given in
the table below.
Note: If an update time that exceeds the restrictions is attempted then a connection by the PLC will be rejected by the inverter and the
parameter 3144 PROFINET Diagnostic will be in the CONNECTION REJECTED state.
It is recommended to increase the update time for larger mapped cyclic I/O data.
