hello,

i am using step motor in my project, i have implemented some delay to achieve max speed. the motor is rotating but not at my required speed. i reduced the delay further but
the motor does not rotate, i believe that the threshold is reaching. i would like to increase
the speed further without altering the hardware. i am using L297 and L298 driver IC.
the motor type is bipolar two pole step motor (18°/step).

i have seen the step motor with same configuration and same hardware rotating at greater speeds. so i feel it is the software that i have to modify.

please suggest me some delay routines which enhances the speed.

below is the delay i am using,

SDELAY:

MOV R2,#0x40
MOV R3,#0x05
loop3:nop
DJNZ R2,loop3
DJNZ R3,loop3
RET
