Control
Bit 06, start possible/start not possible
If [1] PROFIdrive has been selected in
parameter 8-10 Control Word Profile, bit 06 is 1 after a
switch-off acknowledgement, after activation of OFF2 or
OFF3, and after switching on the mains voltage. To reset
Start not possible, set bit 00 of the control word to 0, and
bits 01, 02, and 10 to 1.
Bit 07, no warning/warning
Bit 07=0 means that there are no warnings.
Bit 07=1 means that a warning has occurred.
Bit 08, speed≠reference/speed=reference
When bit 08=0, the current speed of the motor deviates
from the set speed reference value. The deviation may
occur, for example, when the speed is being changed
during start/stop through ramp up/down.
When bit 08=1, the current speed of the motor
corresponds to the set speed reference value.
Bit 09, local operation/bus control
Bit 09=0 indicates that the frequency converter has been
stopped with [Stop] on the LCP, or that [0] Linked to hand
or [2] Local has been selected in parameter 3-13 Reference
Site.
When bit 09=1, the frequency converter can be controlled
through the serial interface.
Bit 10, out of frequency limit/frequency limit OK
When bit 10=0, the output frequency is outside the limits
set in parameter 4-52 Warning Speed Low and
parameter 4-53 Warning Speed High.
When bit 10=1, the output frequency is within the
indicated limits.
Bit 11, no operation/operation
When bit 11=0, the motor does not turn.
When bit 11=1, the frequency converter has a start signal,
or the output frequency is higher than 0 Hz.
Bit 12, drive OK/stopped, auto start
When bit 12=0, there is no temporary overload of the
inverter.
When bit 12=1, the frequency converter has stopped due
to overload. However, the frequency converter has not
switched off (tripped) and starts again after the overload
has ended.
Bit 13, voltage OK/voltage exceeded
When bit 13=0, the voltage limits of the frequency
converter are not exceeded.
When bit 13=1, the direct voltage in the DC link of the
frequency converter is too low or too high.
Bit 14, torque OK/torque exceeded
When bit 14=0, the motor torque is below the limit
selected in parameter 4-16 Torque Limit Motor Mode and
parameter 4-17 Torque Limit Generator Mode.
When bit 14=1, the limit selected in parameter 4-16 Torque
Limit Motor Mode or parameter 4-17 Torque Limit Generator
Mode is exceeded.

Programming Guide
Bit 15, timer OK/timer exceeded
When bit 15=0, the timers for the motor thermal
protection and thermal frequency converter protection
have not exceeded 100%.
When bit 15=1, a timer has exceeded 100%.
