This article explains the internal circuity behind J5 connector of Argon servo drive.
Exceeding ratings may affect drive operation and cause instability or even damage the drive. |

Pin electrical categories
Supply
Supply pins output a regulated 5V voltage to external circuits. GND pin is tied to J3 connector V- terminal.
- Electrical properties
- Output voltage 4.9-5.2 V
- Maximum load 500 mA
- Maximum injected current -10 mA
Never connect multiple supply outputs parallel. Supply output may be connected only current consuming circuity to prevent current injection to the supply port. |
High speed digital input
HSIN is differential digital input capable of receiving digital signals up to 4 MHz.
- Electrical properties
- Maximum voltage to +/- pins referenced to GND: -0.5 to 6V. Nominal 3.3 or 5.0V.
- Maximum injected current +/- 10 mA
- When negative input (-) is left floating, it floats around 2.5V
- Input state reads 1 when voltage at positive pin is greater than voltage of negative pin, otherwise it reads 0
- Wiring when driving using differential source
- Positive (+) inputs: to positive outputs of source
- Negative (-) inputs: to negative outputs of source
- GND must be connected to source ground
- Wiring when driving using single ended source (TTL, CMOS or open collector)
- Positive (+) inputs: to outputs of source
- Negative (-) inputs: leave floating
- GND must be connected to source ground
