If you are using motors of the same power rating, you can use p2372 to define whether the
motors are to be activated/deactivated following the setting specified in p2371 (p2372 = 0) or
based on the operating hours (p2372 = 1, 2 ,3. Details see parameter list).
Parameters to set and activate the cascade control:
p0730 = r2379.0
p0731 = r2379.1
p0732 = r2379.2
p2200 = 1
p2251 = 0
