hi,
Can you post ALL of the PIC program so that we can see the method that you are using.?

If its in 'C language' someone else will help out, I write in assembler.

this is my test program ,cos i want to make sure this motor can run 1st

Symbol pulse1 = PORTC.0 'pulse for m1
Symbol dir1 = PORTC.1 'direction for m1
Symbol pulse2 = PORTC.2
Symbol dir2 = PORTC.3 'direction for m2 vexta

TRISC = %11110000

loop:

dir2 = 1
High PORTC.2 'pulse M2
WaitUs 250
Low PORTC.2 'pulse M2
WaitUs 500

Goto loop

End

hi,
A quick look at the 'program' would suggest to me that it does not meet the requirements of the motor.!

Do you have a copy of the manufacturers software/program.?

i am using PIC uC PIC16F877 to control this motor ,software i am using PIC Simulator IDE (basic based)but according to the manual i need to power up the pulse pins and also the directional pin is it? i mean pin 1 and pin 3 i need to connect to 5VDC and pin 2 and 4 to pulse input pin (PORTC.2) and (PORTC.3) one output pulse signal and another one direction signal.

You must meet the requirements of the motor as shown in the extract attached.

Do you have the controller and the motor.?
The controller expects to be driven from a MCU.

ya i am driving the controller with PIC uC, it seem my motor are now working,as i though the controller is internally power up.after study the extract which you posted it need to connect to VDC because b 4 this i straight away connect the uC input to the corresponding pin without any power go in to the corresponding pin :-)
