How to add spring passes using G71 threading cycle

I'm new to the Okuma control (OSP-P300L-R Control). The machine is a Genos L250E. I am using a G71 to cut an internal thread:

G71 X.750 Z-1.39 H.05 D.008 U.002 B60 F1. J20 M73 M33 A0

The tool makes only one pass at the final diameter. How do I add spring (zero) passes?

Thanks!
