Sinamics V20 + Mach3 + Modbus

[yuemse]

Hi

I couldn't get Modbus communication with the V20. I've made the parameter settings. I get a "receive timeout" error in Mach3 Modbus test.
In the examples, I first do 47e Hex (1150 des) to address 40100. I'm sending the speed information to address 40101. I'm sending 47e hex (1151 des) to 40100.

V20 Parameters
CN0011
p0700 = 5
p1000 = 5
p2023 = 2
p2010 = 6
p2021 = 1
p2022 = 1000
p2014 = 0

Comport
Bits per second = 9600
Data bits = 8
Parity = Even
Stop bits = 1
Flow control = None

You may already got it, if not:

Try with 99 (instead of 40100) for STW and 100 (instead of 40101) for HSW.

Hi yuemse,

Did you manage to get it working?

I'm currently trying to do the same, I was wondering if you're able to share how you got it working?

Kind Regards.
