3 Basics
Basics regarding SINAMICS V90 PN version
SINAMICS V90 PN supports the following telegrams:
- Standard telegram 1
- Standard telegram 2
- Standard telegram 3
- Standard telegram 5
- Siemens telegram 102
- Siemens telegram 105
Siemens telegram 105 is the default for SINAMICS V90 PN. However, since it is for IRT application (which S7-1200 1214C does not support), Standard telegram 1 must be used in this basic application.
Basic parameter configuration regarding SINAMICS V90 PN
Configure PROFINET settings via SINAMICS V-ASSISTANT
The following parameters can be configured using the SINAMICS V-ASSISTANT from the PROFINET settings menu:
In this menu, you can configure:
- Communication telegram: This tab allows checking the PZD (Process Data) structure and values.
- Network: Configuration of network parameters like station name, IP address, subnet mask, and default gateway.
Note: Configurations must be saved and activated, followed by a drive restart.
PROFINET relevant parameters
| Par. No. | Description | Set value |
|---|---|---|
| P922 | Telegram selection | 1 |
| P8921 | PN IP address. There are four indexes. Each index maps to a segment of the IP address. (Note: after successful configuration, values change to 0 automatically.) | Example IP address: 192.168.0.2 P8921[0]=192 P8921[1]=168 P8921[2]=0 P8921[3]=2 |
| P8923 | PN Subnet Mask of Station. There are four indexes. Each index maps to a segment of the subnet mask. (Note: after successful configuration, values change to 0 automatically.) | Example Subnet mask: 255.255.255.0 P8923[0]=255 P8923[1]=255 P8923[2]=255 P8923[3]=0 |
| P8925 | PN interface configuration (Note: after successful configuration, values change to 0 automatically.) | 2 Note: after setting P8921 and P8923, P8925 should be set to 2 for activating PN communication. |
| r8931 | PN IP address of station active | |
| r8932 | PN default gateway of station active | |
| r8933 | PN MAC address of station |
Configure ramp-function generator via SINAMICS V-ASSISTANT
The ramp-function generator configuration is done via the SINAMICS V-ASSISTANT's Parameterize menu. You can activate or deactivate it via the "Set parameter setpoint" tab.
Note: A drive restart is required after activating or deactivating the ramp-function generator.
The application uses the basic ramp-function generator. The generator controls speed over time, featuring acceleration (ramp-up time p1120) and deceleration (ramp-down time p1121). The extended version also includes initial and final rounding-off times to smooth the transitions.
Ramp-function generator relevant parameters
| Par. No. | Description | Set value |
|---|---|---|
| P1115 | Ramp-function generator selection | 0 |
| P1120 | Ramp-up time | 10 s |
| P1121 | Ramp-down time | 10 s |
| P1130 | Initial rounding-off time | 0 s |
| P1131 | Final rounding-off time | 0 s |
