S in “Speed setpoint” mode
Enter a gearbox step–down ratio
(P3, e. g. for 1 : 4.5 ––> P3 = 4.5)
Traversing distance per revolu-
tion at the gearbox output (P2)
Determine the ramp–up time (P9)
Determine the override velocity (P24) and
acceleration (P25)
The speed controller is preset in the factory
and this setting should be adequate for
most applications. We recommend that the
factory presetting for P54 (P gain
n-controller standstill) is not increased.
END
The control loop parameters must be
adapted to optimize the system
(refer to Fig. 3-10).
Analog measuring outputs can be used to
support the optimization procedure
(refer to Chapter 6.3).
