how to calculate RPM for 5phase stepper motor

[skalaxy]

i need to run PF569-AC stepper motor using INS50-120 driver, bother r from mycom.

the motor spec is torque 16.6(kgcm)
rotor interia 560(gcm2)
basic step angle 0.72'
Phase current 1.4A

can anybody help me how to calculate RPM of this motor?
coz i want to run the motor by giving pulse from labview software.

Speed of the stepping motor depend on the step pulse frquency PPS - pulse per second.

RPM = (revolution/360 degrees) * (StepAngle degrees/step) * (F step/second) * (60 second / minute)

StepAngle is the .72' / step number that you supplied.

F is the step frequency in pulses per second.

If the driver you are using is a half step driver, divide the .72 by two before using it.
