Description
1 = The device controls are ready and react to process data.
0 = The device controls are not ready and do not react to process data.
1 = The frequency converter is ready for operation.
0 = The frequency converter is not ready for operation. This status 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-es-
tablish operation.
0 = There are no faults.

1 = A warning is active.
0 = There are no warnings.
1 = The current motor speed matches the current speed reference within
a given tolerance. The tolerance is product specific.
0 = The motor runs, but the current speed is different from the current
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 the 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.
