Undefined VFD_RS485_RTS_PIN

[Rakishaa]

Hope you are well .

I have the issue connecting xpro V5 with vfd hy02d223b . Have separated RS cable from rest of the cables to avoid interference . Spindle can be controlled manually but not via RS485 port. Would be grateful for any kind of advice. Many thanks .

Settings on VFD: pd1=2 pd2=2 pd5=400 pd163=1 pd164=1 pd165=3

Share some pictures of your wiring? The wiring on the HY manual is backwards for the RS+ and RS- , follow the ones here.

What lights are blinking under the PWM - RS485 switch? Red is xPRO talking, Green is VFD talking

The undefined RTS is ok, this controller uses an auto-RTS control.

Rakishaa,

The first things first... let's do a few things:

• Update your firmware to CNC_xPRO_V5_XYYZ_NO.bin
• Once updated, set the spindle type (spindle type will have been set to "none" after update) - in the command window send the following: $Spindle/Type=HUANYANG (or in some cases $Spindle/Type=H2A), after which you should see a confirmation of the spindle type change in the command window
• Ensure RS485 wiring is less than 1 meter in length, twisted, and connected properly (resistors are optional)
• Verify the PWM-RS485 switch₍₁₎ is set to RS485
• Verify both the red and green LED's below the PWM-RS485 switch are flashing periodically
• Verify your VFD is configured properly using the procedure in the Huanyang-VFD-manual PLEASE REFER TO THE MANUAL SPECIFIC TO YOUR MODEL VFD; not all VFD's are the same despite the name on it

Set the following register values via the VFD touchpad (should be the same on most VFD's - VERIFY ON YOUR SPECIFIC MODEL VFD):	Register	Value	Description
PD000	0	unlock parameters
PD001	2	Command source is RS485
PD002	2	Speed source is RS485
PD163	1	Communications address 1
PD164	1	9600 b/s
PD165	3	8 Bit No Parity - RTU
PD000	1	lock parameters

Also check the following settings (these will setting will vary based on the values indicated on the motor's nameplate and your mains voltage 110VAC vs 220VAC)

Register	Description
PD004	Base frequency as listed on spindle (typically 400)
PD005	Maximum frequency Hz (typical value for spindles is 400)
PD011	Min speed (recommended air-cooled=120 water=100)
PD014	Acceleration time (test to optimize)
PD015	Deceleration time (test to optimize)
PD023	Reverse run enabled (set to 1)
PD141	Spindle max rated voltage (typically 220)
PD142	Max rated motor current (0.8kw=3.7, 1.5kw=7.0, 2.2kw=??)
PD143	Motor poles (typically 2 or 4)
PD144	Rated motor revolution at 50Hz (typically 3000 @ 50Hz and 24000 @ 400Hz)

• If you're still believe your having issues and trying to narrow down ground loop or issues otherwise (partial messages received etc..), load the following RS485 debug firmware: CNC_xPRO_V5_XYYZ_NO_485_debug.bin
  • The RS485 Debug bin file is for debugging VFD RS-485 communication issues and requires USB connection and CNCJS or USB serial sender program
  • this firmware assumes/requires a NO (normally open) e-stop (unplug estop button after debug firmware is loaded)
  • Once connected to the X-Pro using CNCJS will echo commands sent to and from the VFD via RS-485
  • The terminal window will display messages from the X-Pro as Tx:....... and messages recieved from the VFD as Rx:........

In some rare cases where VFD noise is particularly severe (typically only encountered with VFD's on 220V mains); you may need to install an RS485 isolator - see https://github.com/Spark-Concepts/xPro-V5/issues/164#issuecomment-1219037733

I followed the above step with the RS 485 amplifier and still had intermittent issues controlling the spindle. Until I put the Spindle controller in an metal electrical box and grounded the exterior of the box. The box has a slot opening in the bottom I left open for air flow. Everything works now for the first time. The box is listed below.

Herewith my setup with the twisted wire and the RS485 isolation module (see attached photos). Also attached are screenshots of the errors when I try and run the spindle with the M3 command. The spindle does not start from the current setup. Please advise what to do next.
