12.2.2 Opon 2: Change over to the network setpoint during operaon
There are several opons for change-over to the network setpoint.
Example 1: Independent of the network used, a change-over from the standard setpoint
source to the network setpoint is to be possible via a digital trigger (e. g. digital input).
1.Set a standard setpoint source dierent than Network" [5]" in 0x2860:001 (P201.01).
2.Set the desired digital trigger (e. g. digital input) in 0x2631:017 (P400.17) via which the
change-over to the network setpoint is to take place.
The current setpoint source is shown in 0x282B:002 (P125.02).
The setpoint change-over by means of the network control words is only possi-
ble if the controller is acvated via the network 0x2631:037 (P400.37).
The following table describes the change-over to the network setpoint via the dierent net-
work control words:
Network control word Change-over to network setpoint
NetWordIN1 data word
0x4008:001 (P590.01)
Assign the funconAcvate network setpoint [17]" to the bit that is to be used for acvang the network
setpoint.
•
The funcons that are to be triggered via bits 0 ... 15 of the NetWordIN1 data word are dened in 0x400E:
001 (P505.01) ... 0x400E:016 (P505.16).
Bit x Selecon:
0 Standard setpoint source selected in 0x2860:001 (P201.01).
1 Network setpoint
AC drive control word
0x400B:001 (P592.01)
The network setpoint is acvated via bit 6 of the AC Drive control word:
Bit 6 Selecon:
0 Standard setpoint source selected in 0x2860:001 (P201.01).
1 Network setpoint
In order that the acvaon via bit 6 works, "Acvate network control" bit 5 must be TRUE. (Standard)!
If control is to be iniated via bit 6 without "Acvate network control" bit 5, the selecon "Network setpoint
acve [116]" must be set in 0x2631:017 (P400.17).
LECOM control word
0x400B:002 (P592.02)
The setpoint is selected via bit 0 and bit 1 of the LECOM control word:
Bit 1 Bit 0 Selecon:
0 0 Standard setpoint source selected in 0x2860:001 (P201.01).
0 1 Frequency setpoint preset 1 0x2911:001 (P450.01)
1 0 Frequency setpoint preset 2 0x2911:002 (P450.02)
1 1 Frequency setpoint preset 3 0x2911:003 (P450.03)
CiA 402 Controlword
0x6040
In case of control via the device prole CiA 402:
•
In the operang mode "CiA: Velocity mode [2]", the setpoint speed dened via the "Target velocity"
0x6042 (P781.00) parameter is used.
•
A change-over to an alternave setpoint source via the CiA 402 Controlword is not possible.
