27 HB 13.0001-EN 3.0
ƒ Travel data set not executable:
Here it is displayed that an error has occurred while carrying out the current travel data set.
In case of the Profibus operation, this mostly occurs when a travel data set with the
controller type ”Speed” in the operating mode ”Positioning” is started. If a travel data set
is started from the user program, the motor is automatically switched to the correct
operating mode without further measures by the user being required.
ƒ
Definition of software limit switch:
Due to incorrectly set system parameters, a fault message is output here. The fault occurs
if during a reference run to a software limit switch the limit switch in question cannot be
reached in a linear system due to incorrectly set system parameters. Thus, for ”Direction,
positive/left” in the ”System” menu, the position value for the left software limit switch
has to be higher than that for the right one, and vice versa.
ƒ Drive inhibited:
The drive shaft either is mechanically blocked, for instance by a gearbox damage, or the
torque set in the current travel data set is too low.
ƒ Internal error:
This error message at present is not yet assigned.
ƒ
Position encoder:
For determining the actual position by means of the resolver, an error has occurred. The
cause of fault can be due to an open circuit between the inverter and resolver or to a
defective resolver.
