Description
0 = Ignores the current process data. This is linked to the submodule where the CTW is present. If
signals are to be covered, the CTW/STW profile (for example, the iC Speed Profile) must be part of
the signals list.
Uses the previously processed data when the data valid bit was true (no control by PLC).
Reserved for future use.
These bits are reserved for application-specific advanced control. For more information, refer to
the application guide.
Description
1 = The device controls are ready and react to process data.
0 = The device controls are not ready do not react to process data.
1 = The frequency converter is ready for operation.
0 = The frequency converter is not ready for operation. This does not involve faults and
warnings as they are indicated in their respective bits elsewhere.
1 = There are no active coast signals, and the motor can start when a start signal is given.
0 = The frequency converter has an active coast signal and has released the motor.
1 = A fault has occurred, and an acknowledge signal is required to re-establish operation.
0 = There are no faults.

1 = A warning has occurred.
0 = There are no warnings.
1 = The present motor speed matches the present speed reference within a given toler-
ance. The tolerance is product specific.
0 = The motor runs, but the present speed is different from the present speed reference,
for example while the speed ramps up or down during start or stop.
1 = The device is controlled and reacting to I/O and process data.
0 = The device does not react on commands from fieldbus, for 1 of the following reasons:
• CTW Bit 10 = 0.
• HMI is in local mode.
• MyDrive® Insight has taken control.
• Control places do not include fieldbus.
