7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
When DELTA is calculated, it must be taken into account that the torque setpoint limitation
m may change in cyclic operation. This limitation acts on the maximum speed difference
set,limit
n .
max
n = ––––––––––––––––––––––– x –––––––––––––––––––
max
Since the speed setpoint is specified by the NC, there is an operating time between the 611D
speed controller and the NC which is taken into account in the DELTA calculation through
machine data "Op. time factor IPO/NREG cyc. f. RFG" (MD 1665).
DELTA = n
