Thanks Johnny,
I've emailed you now at the address you posted above.. let me know if you don't receive it.

Hi Johnny
My drive is marked L5-750, and Leadshine support confirm from the serial number that it does have analogue input/support. However because it was sold by an online (Aliexpress) trader rather than a registered Leadshine agent, they wont support it beyond this confirmation. I will contact the seller, but I don't have much hope they will help as they're primarily a vendor of second hand drives (though this one was new).

The symptom I am seeing is that the motor does not run when /SON is activated and an analogue control voltage applied.

To troubleshoot the fault, I have disconnected CN1 from the machine, and wired it in a simple test config as per the Trial Run config from the manual, and configured all the relevant drive parameters:

After lots of mucking around I finally put an oscilloscope onto the drive output to see was it was outputing. The waveforms I am seeing at the servo drive motor outputs look unusual (to me). They are:

1. With aux and main power to the drive, and /SON not activated, there is ~ 100V pk-pk waveforms present at the outputs (I assumed in this state there would be no output from the drive).

2. With aux and main power to the drive, and /SON activated, but analogue speed control turned down to zero, there is ~ >300V pk-pk waveforms present at the outputs. This could make sense in terms of applying holding torque to the motor, I'm just again surprised at the magnitude of the voltage.. I'd have thought holding torque would be a lot less than driving torque, so the output voltage would be commensurately lower, but I've not looked at drive output before, so am not really sure what 'good' should look like.

Adjusting the analogue speed control makes little difference to the waveforms (which matches the fact the motor doesn't move when the voltage changes).

After a few seconds, the drive errors with Error 100 (out of position), presumably because the encoder feedback is that the motor is not rotating.

The motor is a non-Leadshine 750W servo, with encoder fitted. The motor/encoder has worked successfully in a previous setup, ie:

- the motor rotates correctly (ie tested using a different servo drive)

- when I disconnect Power Terminal 2 from the drive and meter the U, V W motor connections, the motor phases measure correctly (about 5 ohms each, and all roughly the same)

- the encoder is wired correctly, as the servo drive reports no encoder errors, and when the E5-750 drive was initially connected to the CSMIO/A controller (ie encoder -> E5 -> CSMIO), when I manually rotated the servo motor, the CSMIO showed the encoder position changing correctly.

I've just ordered an RS232 cable to fit the drive, so hopefully when that arrives I can see what the Leadshine Protuner software thinks is happening, though again I'm not sure if it'll be much use.

Lots of head scratching going on..!

I know this is an old thread, but I am having exactly the same problem/symptoms with a Leadshine EL5-750 Servo drive that I'm fitting as a 4th axis to my old Morbidelli 504 CNC with a CSMIO/A controller.
Can you tell me how you identified your servo drive was an Economy model? The label on my drive just says EL5-750, and the LED panel will display the analogue input voltage it's reading, so I've been assuming it's capable of analogue input.

Many thanks,

Hi Mark

I had a similar problem recently with my CSMIO/A which suspect was caused by the 24V input voltage. My machine (Morbidelli Author 504) used a three phase half wave rectifier to produce "24V", ie it wasn't regulated, so would peak to well over 24V, possibly to close to the 30V max.

I wound up sending the controller back to CS-Labs in Poland for repair, which they turned around quickly and at no cost. Meanwhile I installed a 24V DC switchmode supply in the machine to provide true regulated 24V DC.

When the controller came back it worked first time.

Hope that helps.


General Mach Discussion / Setting up manual tool change
« on: August 20, 2015, 03:20:58 AM »
I'm in the midst of upgrading an old Morbidelli Author 504 P2P woodworking router to Mach3.

I've replaced the TRIA7500 controller with a CSMI/O IP/A with pendant and a few extra modbus I/O modules so I can (eventually) use all the drill spindles etc.

I have motion + homing working OK and am working on manual tool change. Before I pulled out the old controller I did (once) manage to get it to eject a tool and accept a new one, so I believe the mechanicals should be working OK (I say "believe" as the machine has obviously done a fair bit of work in it's time and some of the mechanical bits have needed a good service.

I have manuals and circuit diagrams for the machine, but they're not clear about what the various inputs and outputs to the electrospindles do, and in particular, what sequence is necessary to eject a tool. I've created a macro that allows me to cycle through the Outputs and toggle them individually, but I haven't hit on a combination that will eject the tool. To complicate matters, it's clear Morbidelli have implemented some rudimentary logic within the pneumatics as there are several pneumatic logical OR devices amongst the plumbing.

Is there any kind of standard or common usage amongst electrospindle I/O logic? My spindles are marked 11HP SCM "RTNINVER", which I suspect is a rebrand of a more common manufacturer but I can't find any more detail.

The I/O to/from the spindles (according to google translation of the Morbidelli circuit diagrams) is:
Outputs (to solenoids, air to spindle):
- spindle 60mm descent
- spindle 90mm descent
- unlock tool
- clamp extraction
- collet open

Inputs to controller (ie sensors + buttons):
- tool release button
- spindle locked sensor
- spindle rod sensor
- spindle clamp high sensor
- spindle clamp low sensor
- temp sensor sensor

Any help/advice appreciated!
