Description
value
Reference speed
Here, the same value must be specified
as in parameter P2000 of SINAMICS
G.
Reference current
Here, the same value must be specified
as in parameter P2002 of SINAMICS
G.
Reference torque
Here, the same value must be specified
as in parameter P2003 of SINAMICS
G.
SINAMICS G ready for switching on
SINAMICS G ready for operation
i.e. switched on (STW bit 0 is 1),
however, operation is not enabled
(STW bit 3 is 0)
SINAMICS G is switched on and
enabled
Motor follows the setpoint value.
The SINAMICS G outputs a fault.
OFF 2 is not set
OFF 3 is not set
On-inhibit active.
To cancel it, ON_OFF1 must be set to
FALSE, all enables from 1 be set and
possibly pending errors be
acknowledged.
The SINAMICS G outputs a warning.
Setpoint actual value deviation within
tolerance range.
The automation system shall control
the SINAMICS G.
Speed => maximum speed
Comparison value for I,M or P
exceeded
Signal for opening the motor holding
break
No motor over temperature
Rotational direction of the motor.
Output is TRUE, if the motor rotates
forward.
No thermal overload of the power
section
Current speed in U/min.
Negative values mean that the motor
rotates backwards.
Current motor current in A
