21.1 | 1 | You will need a frequency converter (hereinafter referred to as the FC) with support for Modbus RTU control, such as Toshiba VF-S11, to control the spindle via Modbus via the PLCM-B1-G2 expansion board. |
| |
1.1 | 2 | |
| |
21.1 | 3 | Modbus spindle control setting procedure: |
| |
1.1 | 4 | |
| |
21.1 | 5 | 1. Set FC to the control mode using the Modbus RTU protocol (RS-485) and remember the COM port settings in FC (count of bits per second, data bits, parity and stop bits). |
| |
1.1 | 6 | |
| |
21.1 | 7 | Example for Toshiba VF-S11. |

| |
21.1 | 16 | 2. Connect FC to the PLCM-B1-G2 expansion board via RS-485 interface. |
| |
1.1 | 17 | |
| 18 | (% style="margin-left: 30.0px;" %) | ||
| |
21.1 | 19 | 3. Purchase the "[[MODBUS protocol support>>url:http://pumotix.ru/#soft||shape="rect"]]" option or activate a trial period for this option in the menu "Configuration" → "License Manager" → "Common". |
| |
1.1 | 20 | |
| 21 | (% style="margin-left: 30.0px;" %) | ||
| |
21.1 | 22 | 4. Enable and configure Modbus in the menu "Configuration" → "Modbus Setup". |
| |
1.1 | 23 | |
| |
21.1 | 24 | Create new Modbus-master. Number of COM port is PLCM. The rest of the settings should be exactly the same as in the FC (in the screenshot, an example of a standard configuration of the COM port of Toshiba VF-S11). |

| |
1.1 | 27 | |
| |
21.1 | 28 | You need to add registers to control the FC and read statuses from FC. For example you need to configure registers named **SpindleMode**, **SpindleRPM** and **SpindleStatus**. |
| |
1.1 | 29 | |
| |
21.1 | 30 | We recommend using exactly these names, since in the future, registers will be accessed from background operations by their names. |

| |
12.1 | 42 | {{warning}} |
| |
21.1 | 43 | These values can be indicated in HEX (hexadecimal) in the instructions for the frequency converter. For example, 0x1001, 0x1002. |

| |
21.1 | 47 | 5. Create new background operation (macro) through [[the macro manager>>doc:Руководство пользователя.Описание M-кодов.Управление макросами и фоновыми операциями.WebHome]]. |
| |
1.1 | 48 | |
| |
21.1 | 49 | The main task of the background macro is to monitor the current state and spindle speed and send the values to the frequency converter via Modbus. |
| |
1.1 | 50 | |
| |
21.1 | 51 | An example of background operation **modbus_spindle.bm** for ModBus spindle control via FC Toshiba VF-S11 posted in attachment. This file must be added to background operations list. |
| |
1.1 | 52 | |

| |
1.1 | 54 | |
| |
12.1 | 55 | {{warning}} |
| |
21.1 | 56 | Access to Modbus registers from macros is done by the name of the Modbus register case sensitive! For example **SpindleRPM** and **SpindleRpm** are different registers. |
| |

| |
21.1 | 60 | 6. Enable the background operation. Make sure that the operation has started and is working properly. This will be indicated by the green indicator to the right of the operation name. |

| |
1.1 | 63 | |
| |
21.1 | 64 | The spindle should now turn on and off if everything is configured correctly. The spindle speed accordingly must also change at the FC when it changing in PUMOTIX. |
