SINAMICS S120 Fail-Safe Drives
Description
For drive_1 set the following:
Bit0: Control Unit DI1
Bit1: TM54F F-DI1
Bit2: 0
Bit3: Control Unit DI3
Fixed value 1 : 20 rpm
Fixed value 3 : 800 rpm
Fixed value 9 : 1000 rpm
Fixed value 11 : 1000 rpm
Explanation: If the "SLS_door1"
signal is active (in the dia-
gram: "High"), the safety door
is closed and the high speed
setpoint is entered. For a low
signal, a changeover is made
from a high speed (setpoint) to
a low speed (setpoint).
By pressing –S8, when the drive
is operational, independent of the
state of the safety door, a fixed
speed of n=1000 rpm is entered
(speed setpoint). The drive can
only operate for a 1 signal at bit 0.
The reason for this is that DI1 of
the Control Unit is also intercon-
nected with ON/OFF1.
Set the OFF3 ramp-down time
and the standard ramp-down time
under the point Setpoint Channel
/ Ramp-function generator.
