9.8.8 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 IP address of the inverter (slave), see secon Data mapping. ^ 360
4.
Save parameter sengs: 0x2022:003 (P700.03) = "on / start [1]".
5.
In order that the changed communicaon sengs become eecve, there is the opon to
•
switch the inverter o and on again or
•
restart the communicaon, see 0x23B0 (P508.00).
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 ^ 531
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
•
Funcon code 6, i. e. wring into a single register.
Example of an inverter with the node address 1:
Request frame by the master
Slave address Funcon code Register address AC Drive control word
Data: 0b1100001 ≡ 0x0061
Checksum (CRC)
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:
Response message from the inverter
Slave address Funcon code Register address AC Drive control word
Data: 0b1100001 ≡ 0x0061
Checksum (CRC)
0x01 0x06 0x08 0x34 0x00 0x61 0x0B 0x8C
Write the speed of the drive via Modbus
The drive speed can be changed via the Modbus register 42102, see Data mapping.
Example of an inverter with the node address 1:
Request frame by the master
Slave address Funcon code Data Checksum (CRC)
Register address Network setpoint frequency (0.01)
0x01 0x06 0x08 0x35 0x04 0xD2 0x19 0x39
Response message from the inverter
Slave address Funcon code Data Checksum (CRC)
Register address Network setpoint frequency (0.01)
0x01 0x06 0x08 0x35 0x04 0xD2 0x19 0x39
The drive now rotates with a frequency of 12.34 Hz.
