Hello everyone, I'm a beginner in programming and I'm facing difficulties in controlling a stepper motor using studio 5000 software. I have properly connected the stepper driver with a 4-20ma IFM converter. While I can make the motor turn by setting up a pulse generator with two TON timers, the motion is quite erratic. I'm curious if there is a specific instruction that I'm unaware of that can help the motor move smoothly and consistently, or if I'm approaching this incorrectly. Any assistance would be greatly appreciated. Thank you!
Welcome to the forum! Can you please provide the make and model of the stepper motor you are using? Stepper motors operate by utilizing multiple magnets to rotate the rotor. In my experience using a stepper motor, I established a communication link to instruct the motor on the number of steps to move, direction, and possibly the speed. If you are able to control the stepper motor using timers, you are essentially pulsing the stepper one step at a time. I am unsure if it is possible to interface with a 4-20 mA signal, but please feel free to correct me if I am mistaken. - James
To optimize the performance of a stepper motor, it requires rapid pulses for smooth operation. Stepper motors typically have 4 wires and would likely not function properly without a dedicated stepper driver. Make sure you're dealing with a stepper motor and not a DC motor controlled by PWM. While I'm not familiar with Studio software, Mitsubishi FX Series PLCs offer specific outputs (particularly the first 4) with unique functions that can generate PWM signals ranging from 0-2kHz or higher. It's rare to find a PWM signal below 200Hz, which may result in slightly uneven movements.
Could you kindly provide the part number for your IFM module? This information will help us assist you more effectively.
User alan_505 requested the part number of my IFM module. I am currently utilizing an IFM AL1122 I/O link in conjunction with a DP1213 analog signal converter for my setup.
James Mcquade warmly greeted forum members by asking for the make and model of the stepper motor in question. He admitted that he might not have all the correct information and welcomed any corrections. A stepper motor operates by utilizing multiple magnets to rotate the rotor. In his past experience with a stepper motor, he utilized a communication link to control the number of steps, direction, and possibly the speed. When employing timers to turn the stepper motor, it pulses the motor one step at a time. The possibility of using a 4-20 mA interface is unknown to him. In his specific case, he is utilizing a Kamoer pump model #KK300-ST in conjunction with a Stepperonline driver part #DM542T.
Hey there, it sounds like you've got a good handle on the basics! If you're seeing erratic motion in your motor, the issue might be related to the speed at which you're sending pulses, or even a problem with the timer settings. Studio 5000 does indeed have a function block - 'AXIS_CIP_SYNC_SERVO' that might help you out in getting the smooth, consistent motor movement you're looking for. It allows precise control over speed, acceleration, and deceleration. I would encourage you to take a look into its documentation and also don't forget to check if your motor and drive are indeed compatible with this function. Good luck!
Hey there, it sounds like you're on the right track, but facing a common hurdle for beginners in programming motor control - don't worry, we've all been there! One possible issue contributing to the erratic motion could be that the stepping rate your pulse generator is supplying on the TON timers doesn't match the capabilities of the motor. In Studio 5000, you might want to consider using the PTO (pulse train output) instruction for controlling the stepper motor. This provides a more stable and controlled pulse width which can ensure smoother motor operation. Ensure your hardware supports PTO. If you have any more questions, feel free to ask. Keep experimenting, you'll get there!
Hey there, kudos to you for diving into the world of programming. To make the motor move smoothly, I'd suggest you ensure the pulses sent to the stepper motor are evenly spaced. If the pulses aren't uniform, the motor will seem to 'jerk' or move erratically as you've described. Also, consider looking into the SSC instruction (Synchronous Serial Communication) which might help streamline communication between your devices. Of course, this is just a suggestion and different setups might require different solutions. Keep exploring and learning, you're doing great!
Hi there! It sounds like you're doing a great job experimenting with the basics. The erratic motion of your stepper motor might be due to the timing settings of your TON timers. Instead of utilizing two TON timers for pulse generation, I'd recommend using the PTO (Pulse Train Output) instruction if your ControlLogix supports it. The PTO instruction is designed to control the speed, acceleration, and position of pulse-controlled axes like your stepper motor. That should help you achieve smoother and more consistent movement. Remember to carefully configure your PTO; wrong settings might lead to unexpected behavior. Keep practicing and don't get discouraged!
