9.5.12 Short setup
In the following, the steps required for controlling the inverter via Modbus are described.
Parameterisaon required
1.
Acvate network control: 0x2631:037 (P400.37) = "TRUE [1]"
2.
Set network as standard setpoint source: 0x2860:001 (P201.01) = "Network [5]"
3.
Set Modbus node address.
•
Each network node must be provided with a unique node address.
•
Details: 4Node address seng ^ 227
4.
Set Modbus baud rate.
•
Default seng: Automac detecon.
•
If the automac baud rate detecon funcon is acvated, the rst 5 ... 10 messages
are lost aer switch-on.
•
Details: 4Baud rate
seng ^ 227
5.
Set Modbus data format.
•
Default seng: Automac detecon.
•
If the automac data format detecon funcon is acvated, the rst 5 ... 10 messages
are lost aer switch-on.
•
Details: 4Data format seng ^ 228
6.
Save parameter sengs: 0x2022:003 (P700.03) = "on / start [1]".
7.
Switch the inverter o and then on again in order that the changed communicaon set-
tings can get eecve.
In the default seng, the digital input DI1 is assigned with the "Run" funcon. If
the network control is acvated, this funcon serves as "start enable" for start
commands via network. Hence, the digital input DI1 must be set to HIGH level in
order that the motor can be started via network. 4Start / stop motor ^ 350
Starng/stopping the drive via Modbus
For starng/stopping the drive, Modbus register 42101 can be used.
•
Modbus register 42101 is permanently assigned to the AC Drive control word 0x400B:001
(P592.01).
•
In the frame, the leading 4 is omied in the addressing process. The numbering of the reg-
isters starts with 1; addressing, however starts with 0. Therefore the address 2100
(0x0834) is used in the frame when register 42101 is wrien.
Bits set in the AC drive control word:
•
Bit 0 ≡ Run forward (CW)
•
Bit 5 ≡ Acvate network control
•
Bit 6 ≡ Acvate network setpoint
Example of an inverter with the node address 1:

Register address AC Drive control word
0x01 0x06 0x08 0x34 0x00 0x61 0x0B 0x8C
If digital input DI1 ("Start enable") is set to HIGH level, the drive should start and the inverter
should respond with the same frame as conrmaon:
