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

The HSIN circuity inside the drive. Left side end represents J5 pins and right side continues to drive internal circuity.

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 on positive pin is greater than voltage on 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
