The spindle position accuracy must be lower than on minute(Degree-Minute-Second) .If the position deviate from this limit the tolerances of workpiece will not acceptable.
Thank you.
Hello
I have a problem with industrial control.
When I want rotate a circular part (Like CNC lathe spindle) to an accurate position, , the spindle deviate at final position because of inertia moment so that I can not adjust the accurate position.
For solving this problem, I used gearbox...
Yes,Okay
I understand that Assembler is better for programming PIC micro.
How can i learn assembly for PICs ?
Please intruduce me weblink or PDF to learn that.
Thanks.
Hello
There are several languages for Programing PIC micros(e.g. PICBasic,Assembly,C).
Please discuss about PIC programing languages and beneifits.
I think Assembly language is the powerful way but PIC Basic is simplest way.
Thanks.
Proteus Software
Hi
I want use PIC microcontroler to driver industrial motors.
I want simulate my circuit before i make it ,So i want use PROTEUS software.But i do not know how i can use PIC microcontrolers in PROTEUS software.
Thank.
dc-dc converter pwm frequency
OK, understand that the control driver contain herein parts:
1) Microcontroler that makes PWM pulses
2) Current amplifier of Micro pulses that triggers the DC motor driver(MOSFET)
3) Driver that controls the DC motor RPM with switching method.
My question is...
best cnc motion control
I think in CNC & Robotic ,To determine the position of Arm/Support we can use Resolvers .
Resolvers have low cost ,very economic and good precision.
Thanks.
I want control a high power DC motor.
Refer to discussions in this useful forum ,I understand that PWM method is the best way.I construct PWM pulses ,but i have two problem with it:
1) With microcontrollers(PIC) I construct PWM pulses with 5Volt amplitude ,But i need 250Volt amplitude to setup...
I want use TRIACs ,because TRIACs are used for high power control.
Can I use Power transistors for high power control (e.g. 220Volts & 10Amps)?
In the PWM method Freq of pulses is 100-1000 Hz .
Can I use the Power Transistore for construct PWM pulses, In this range of frequencies ?
Thank You
220 dc motor
I want control a industrial 220Volt DC motor with microcontroler such as PIC16F877
with PWM(Pulse Width Modulation) method.
I programed the microcontroler to construct pulses with 2-99 percent
duty cycle ,but i do not know , how trigger the high power DC motor with...
Yes I know that
But I want use this type of controller in a package with other equipment.
Your Advice is usefull when I want control just one AC motor.
I use the PIC family microcontrollers to control the low power DC motors.
In this case ,I use the Magnetic-Relay to join the microcontroller low power pulse to the DC motors electric power.Now i want to use the AC powerfull motors.
Pls guide me to use the Triac & Optocoupler & other parts to...
