Bit 03, No error/Trip
When bit 03 = "0", no error condition of the frequency
converter exists.
When bit 03 = "1", the frequency converter has tripped
and requires a reset signal before it can start.
Bit 04, ON 2/OFF 2
When bit 01 of the Control word is "0", then bit 04 = "0".
When bit 01 of the Control word is "1", then bit 04 = "1".
Bit 05, ON 3/OFF 3
When bit 02 of the Control word is "0", then bit 05 = "0".
When bit 02 of the Control word is "1", then bit 05 = "1".
Bit 06, Start possible/Start not possible
If PROFIdrive has been selected in 8-10 Control Word Profile,
bit 06 will be "1" after a switch-off acknowledgement, after
activation of OFF2 or OFF3, and after switching on the
mains voltage. Start not possible will be reset, with bit 00
of the Control word being set to "0" and bit 01, 02 and 10
being set 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. This may occur, for
11 11
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 by means of the stop button on the LCP, or
that [Linked to hand] or [Local] has been selected in
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 4-52 Warning Speed Low and 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.
