SMV2BRK
SMV2BRK is a product name for for SimpleMotion V2 break out board. The purpose of SMV2BRK is to:
- Terminate the RS485 bus (be the last device on the bus with proper termination impedance)
- Break out the enable and STO signals for easy wiring through wire terminals
Before using SMV2BRK, be sure to understand SimpleMotion V2 port.
Properties
| Pin | Name | Function |
|---|---|---|
| 1 | GND | Ground for 24V power supply. Will be same tied with ground of drive logic supply voltage and SimpleMotion V2 USB adapter (PC ground). |
| 2 | V_IN | 24VDC supply to SMV2BRK. Use same 24V supply that is used to feed drive 24V logic voltage. |
| 3 | ENA | Enable signal input. Drives disabled when open circuit or pulled to GND, enabled when connected to 24VDC. |
| 4 | V_OUT | 24V output, connected to V_IN through on-board fuse. Used to feed voltage to switches. |
| 5 | STO1- | STO number 1 negative input. When STO in inactive (motor able to produce toreque), tie GND to this pin. To activate STO1, leave STO1-, STO1+ or both floating. |
| 6 | STO1+ | STO number 1 positive input. When STO in inactive (motor able to produce toreque), tie V_OUT to this pin. To activate STO1, leave STO1-, STO1+ or both floating. |
| 7 | V_OUT | 24V output, connected to V_IN through on-board fuse. Used to feed voltage to switches. |
| 8 | STO2 | STO number 2 input. STO2 is referenced to GND and to inactivate STO2, connect V_OUT to STO2. To activate STO2, leave floating. |
| 9 | V_OUT | 24V output, connected to V_IN through on-board fuse. Used to feed voltage to switches. |
Usage
SMV2BRK is intented to be wired to E-stop button of the motion control system. The following diagram illustrates the preferred wiring:
For testing purposes, or if no STO or Enable need to be controlled, SMV2BRK may be wired by short pieces of wire which always keep STO disabled and Enable active:
