Table A-7 Control word set-up
Parameter Value Meaning
P75.22 75.08 Control word 1 = P75.08 = PPO PZD1.
P75.27 0 PPO PZD6 word not used.
Having configured the parameters to transfer data to a Fieldbus
control reference the user has the option of declaring a ‘fallback’
value for that control reference. This will be dealt with later.
Once the Fieldbus control reference has been configured it is
necessary to configure the start and stop control bits source to
come from Fieldbus control reference 1. Each of the drive control
bits has a parameter that sets up where the source of that control
bit is. Referring to Table A-8, for the start bit this parameter is
P33.01 for the stop bit this parameter is P33.00. These parameters
need to be configured to source their values from the Fieldbus
control reference. Fieldbus control reference 1 contains values
5.100 to 5.115 which are Fieldbus control reference 1 bits 0 to 15,
values 5.200 to 5.215 are Fieldbus control reference 2 bits 0 to 15.
Table A-8 Control flag source set-up
Parameter Value Meaning
P33.00 5.100 Stop control flag source - 5.100 Fieldbus
control word 1, bit 0
P33.01 5.101 Start control flag source - 5.101 Fieldbus
control word 1, bit 1
P34.16 1 Pass Start/Stop control to the control flags
A.8 Status Word
Any drive status word can be sent to the Fieldbus, either a pre-
defined one from Menu 11 or a user-configured one from Menu 41.
This example, shown in Table A-9, will send the first 16 Status
Flags in P11.30, (as TX STS WRD 1 SOURCE).
