"x" means any value.
Bit 7, Warning, can be set at any time. It indicates a device-internal warning message. The evalua-
tion of the present warning is carried out by reading out the warning status with Parameter
Warnings
270.
Bit 10 "Reference value reached" is set when the specified reference value is reached. In the spe-
cial case of power failure regulation, the bit is also set when the power failure regulation reaches the
frequency 0 Hz. For "Reference value reached" there is a hysteresis (tolerance range) which can be
set via parameter
Reference Value Reached: Hysteresis
549.
Bit 11 "Limit value reached" indicates that an internal limit is active. This may be the current limit,
the torque limit or the overvoltage control. All functions result in the reference value being left or not
reached.
Bit 15 "Warning 2" signals a critical operating state which will result in a fault switch-off of the fre-
quency inverter within a short time. This bit is set if there is a delayed warning relating to the motor
temperature, heat sink/inside temperature, Ixt monitoring or mains phase failure.
Frequency Inverter Control
10.2 Control via Statemachine
In the operation mode "Control via Statemachine" (
Local/Remote
412 = 1) the frequency inverter is
controlled via the Control Word of the Statemachine.
Transition 4 to state "Operation enabled" is only possible if the Controller Release via STOA and STOB
and one of the digital inputs for Start Right or Start Left is set.
Object
0x6040/0 Control Word
is used for the frequency inverter if Parameter
Local/Remote
412 is
set to "1 – Control via Statemachine".
