With jog 1 or jog 2 (c1055 OR c1056 =1): Freeze of ramp-function generator is locked (r0898.5 = 1-signal).
With simultaneous jog 1 and 2 (c1055 = c1056 = 1): ramp-function generator is frozen and the last setpoint remains effective (r0898.5 = 0-signal).
With activated Technology controller (c2200 > 0, p2251 = 0) the ramp-function generator is bypassed (r2349.5).
