Operating Instructions, 01/2011, FW 4.4, A5E02430659B AD
To avoid frequent activation/deactivation of the uncontrolled motors, a time can be specified
in p2377 which must have elapsed before a further motor can be activated/deactivated. After
the time set in p2377 has elapsed, a further motor will be activated immediately if the PID
deviation is greater than the value set in p2376. If, after p2377 has elapsed, the PID
deviation is smaller than p2376 but greater than p2373, the timer p2374 is started before the
uncontrolled motor is activated.
The motors are deactivated in the same way.
