==Testing regenerative drive transistor==
 
Use this method to test regenerative drive transistor (which burn if regenerative resistor resistance is too low, or it has a wiring short circuit):
 
#Measure resistance between BR and VN terminals when drive is off and all connectors have been unplugged. If resistance is below 10 kΩ, the regenerative drive transistor damaged.
 
 
{{info|This failure will also probably cause the fault where drive HV DC supply voltage does not rise when powered-on. For more details, see [[Argon supply voltage troubleshooting]].}}

[[File:Argonj2schema.PNG|thumb|Schematic diagram consisting RS485 receiver and few other components connected to Argon's J2 port]]SimpleMotion V2 port (J2 on argon) is protected by clamping diode (type NXP PESD5V0S4UD) that is identified as D19 in the adapter and Argon drive. That diode typically burns if 24VDC is miswired in the port or if faulty Ethernet/RJ45 cable is being used. Same diode exists also in the [[SimpleMotion V2 USB adapter]] and may be damaged as well. Sometimes fault propagates longer and kills also RS485 driver chip (Texas Instruments SN65176BDR) which is identified as IC4 on Argon and IC1 on SM V2 USB Adapter.

{{tip|As D19 is a protection device, drive works without it as well, so it is possible to repair the drive just by removing D19. However without the diode, rest of the electronics inside drive are vulnerable to the same error that caused D19 to burn. Operating without D19 will always terminate warranty.}}
