VXM Step Motor Controller

VXM Controller

Velmex offers several VXM Stepper Motor Controllers to govern the performance of the motors available for Velmex products. They make precise positioning of the slides, stages and tables simpler and more effective.



Velmex VXM™ Controllers Control Motion On Multiple Axis

Velmex VXM Controller Systems are components that drive motorized Velmex products including UniSlides®, BiSlides®, XSlides™ and Velmex Rotary Tables. The VXM's advance design delivers high, consistent performance and insures they are very efficient, reliable and easy to program.

Velmex pioneered the development of a microprocessor-based indexer/driver controlling one, up to four axes in a single system. This 2-phase, unipolar stepper motor controller has the capability to drive and control precise movements, multi-axis and velocity. Velmex's VXM Controller System is capable of controlling to 4 motors, 1 motor at a time. Also two motors can be controlled simultaneously for coordinated motion.

Velmex VXM Systems can be used with a PC, Tablet, Laptop or PLC or can run standalone. Velmex also offers a simple, variable speed and teachable two-move version of the popular VXM™ series of step motor controller systems.

 


Velmex VXM™ Controller Features

The VXM Controller uses a half-step switching sequence to drive the motor. It has a programmed look-up that maximizes the motor torque. It constantly is optimizing the efficiency of the motor and therefore, doesn't lose torque. This delivers higher resolution and lowers the noise and susceptibility to motor resonance.

XSlide Features


Velmex VXM Systems enable the step motor to operate more efficiently by utilizing pulse width modulation current control, with an automatic motor power-down for lower power consumption. The system's microprocessor is in total control of the voltage level on each phase of the motor drive which eliminates the noise interference.

VXM™ Troubleshooting
Click to Open

Troubleshooting

First - always read the Users Manual.Reconfiguration Label for VXM Controller

Whenever you have an issue with the VXM Controller controlling the motor(s), check to be sure the system is configured correctly. The VXM needs to be set-up to recognize the specific motor and axis it is controlling. Install and run COSMOS™ Configurator Software to program the VXM to properly operate the connected motors.

If the VXM does not appear to be controlling the motors properly, run diagnostics. First run the Serial Port Diagnostics. This will indicate whether or not you are communicating with the VXM Controller. If you are not communicating with the Controller, the system may not be configured correctly or you may have an issue with the communications port. Check both.

If the Serial Port Diagnostics runs correctly, but you still have issues, then run the COSMOS Systems Diagnostics. This can help you and Velmex Support, should you contact us, determine what the issue is and how to resolve it.

Issues with Equipment
Symptom Possible Cause
Power (Green LED) light does not come on. Power supply not connected or AC cord not attached. Power switch not on. Circuit breaker tripped (white center protruding from breaker.)
Controller not communicating with computer. If when running diagnostics, the USB cable LEDs do not flash, you could have: a bad connection/cable, wrong USB driver, wrong component/cable. If you have a Velmex RS232 to USB cable, the LEDs will flash when any command, including the diagnostics is sent.
Motor makes noise but is not moving (Stalled). VXM not configured for Motor, speed too high, broken wiring, or jammed mechanism/motor.
Motor is not making any noise and is not moving (no power to motor). Limit switches not connected or set for wrong type switches.
Circuit breaker trips when power applied to VXM. Voltage >28 volts or polarity reversed.
Circuit breaker trips while running motor for a short time. Wrong motor selected. Shorted wiring.
Circuit breaker trips while running motor for a long time Wrong motor setting. Shorted wiring. Controller overheating from lack of ventilation or ambient temperature too high.
Controller is too hot to touch. (It is normal for Controller and Motor do get very warm when running continuously.) Wrong motor setting. Lack of ventilation or ambient temperature too high. NOTE: Motor should always be mounted for heat conduction.
Motor runs erratically (at lowest speeds goes either direction, and has low torque at mid speeds). Broken wire to motor or broken connector pin.
Motor always goes opposite direction. Directions were inverted with the "setDM" command. Refer to the "getDM" and "setDM" command.
VXM resets itself and sends "EB" to the host. A motor 3 or 4 command was sent to the VXM when there is not a second VXM connected to the VXM bus.
VXM continuously resets itself (flashes power light slowly) and sends "EB"s to the host. A master VXM attempts communication with a slave that is off.
Power (Green LED) light flashes rapidly and continuously on power-up Run, Stop, or a Jog input is pulled low. The VXM does not allow button Jog inputs to be activated at power up. (release button/input to recover.)
On-Line light flashing continuously (yellow LED). RS-232 overrun error, host sent commands while VXM was busy sending requested data (power off/on to recover.)
Power and On-Line light flash rapidly and VXM sends "EM" to the host. Program memory is full (send "K" to recover.)
Power and On-Line light flash rapidly and VXM sends "EL" to the host. More than 10 nested Loop commands encountered per run (send "K" to recover.)
Power and On-Line light flash rapidly and VXM sends "EJ" to the host. More than 4 nested "JMx"s encountered per run (send "K" to recover.)
Power and On-Line light flash rapidly and VXM sends "EC" to the host. When "U9x" missing or motor not the same when continuous indexing (send "K" to recover.)

VXM™ FAQs
Click to Open

Is it possible to control more than one axis with the VXM Controller?

Yes, VXM configurations can control up to 4 motors, 1 motor at a time. The VXM-4 System can handle 4 motors and consists of 2 linked VXM Boxes. Two motors can also be controlled simultaneously with the VXM1-1. Click on the "Specifications Tab" above for more details and specifications.

Is it necessary to connect the VXM Controller to a computer?

In order to program the VXM Controller for your specific application, it should be connected to a PC, Laptop, Tablet or PLC. Once downloaded with a program, it can operate without the computer connection. However, the VXM-1J Control has a simple jog and auto-reverse functioning and does not require a computer to program.

Will Velmex motorized stages work with other motors and controllers?

Yes, if you have your own motors and controllers, you can use them with Velmex motor-ready products. The VXM Controller, however, has been specifically designed to optimize stepper motor control. Its a very dependable and low cost solution for high precision positioning requirements. Velmex motorized stages, motors and the VXM Motor Controller come as a complete system, ready to plug in. Click on the "Specifications Tab" above for more details and specifications.

I have my motor and the VXM connected, why won't the motor move? Reconfiguration Label for VXM Controller

Has the VXM driver and the motor been configured? The VXM needs to be set-up to recognize the specific motor and axis it is controlling. If after installation and configuration, the VXM does not appear to be controlling the motors properly, follow the troubleshooting steps in the VXM Users Manual and run the System Diagnostics.

Does the stepper motor and/or VXM Controller give any indication it is not running properly?

Depending on the situation, the system may sound different than it does under normal operation. See "Troubleshooting above" for sound bytes to help troubleshoot motor and controller operation.

What is the default speed of the VXM controller?

The default speed of the VXM Controller is 2,000 steps per second.

I want to use an Arduino controller. Will it work?

It is not recommended. An Arduino cannot generate enough torque to allow the motor to operate within the normal speed ranges.
