Alarm No. 20 on the amplifier means “Encoder error”. Swap-tronics is the easiest solution to learn if it’s the cable or the encoder itself. Encoder cables are availble for replacement. And so are J2S motors. Repair is also an option. www.motadistribution.com
Q. What type of grease is used in Oriental Motor GN/GU Type gearheads? A. Parallel gearheads: Molybdenum grease Right angle gearheads: Molybdenum grease (parallel shaft section); Urea grease (hollow shaft section)
Machine Design Article by Mindy Lin Cheng 8/22/2007: It’s hard to stay up to date when you are floating in a sea of technical jargon. However, it’s imperative that engineers know the terminology associated with the areas in which they work. And that’s especially true if their assignments take them outside their engineering discipline. For […]
First, separate the gearbox from the motor. On the first stage of teeth, make a notch on one of the teeth. Not a big one or it’ll make noise when it’s put back together. Then turn the shaft of the motor until the notch makes a full revolution. The number of times that you have […]
When e-stop is wrong, and you receive alarm. Check connection: Pin 2 of CN1 of EMP. And ensure Pin2 connect to 25, 25 to -DC24v, and 7 to +DC24v. www.motadistribution.com
The detent torque value of a VEXTA stepper is about 3% of the Holding Torque value but Oriental Motor does not specify the value. It is just a rule of thumb.
When all of your hyperterminal settings are correct, and you’re using the Oriental Motor communication cable, but you still can’t communicate through your PC’s COM port, you should check to ensure that your I/O has power. This is true for Alpha Step Plus Stepper Motor/Driver packages and the EMP_Series_programmable controller. Do not use 5VDC and […]
There is a difference of winding between ACmotors and Synchronous Motors. Motor resistance resistance of main winding of auxikiary winding 3IK15GN-A 53.5Ω 77Ω 3IK15GN-AW 59.6Ω 58.8Ω 3IK15GN-AUL 70.3Ω 71Ω 3SK10GN-A 57.6Ω 306.8Ω 3SK10GN-AUL […]
Sometimes it’s necessary to mount a stepper motor in a different orientation, or the opposite direction is needed at the motor, but there is no access to the driver control – given the same pulse and direction signals. Using 6 lead wire unipolar driver, how do I change the wires around to accomplish this? A: The A-phase lead-wires are normally Black, […] […]
