Bit 7: Fault acknowledge
This bit is used to acknowledge faults in the drive. When a rising edge (0 -> 1) is seen in this bit by
the option board, it requests the drive to acknowledge present faults. The functionality of this bit is
rising-edge sensitive only.
Bit 10: Control by PLC
This bit is used by the master to indicate that it is in control of the slave and that the commands sent
via fieldbus are valid.
During operation, this bit must be 1. If the drive is not operating and this bit is 0, the drive cannot be
started.
If the drive is operating, and this bit becomes 0, the option board freezes the process data provided
to the drive, and sets its state to FAULT. The drive reaction to this fieldbus fault depends on the drive
parameterization.

PROFIdrive Status Word 1 (ZSW1)
The table below lists the assignments of the status word 1.
Table 67. Overview of the assignments of bits of the status word 1
Bit 0: Readiness to switch on
This bit indicates whether the drive is ready to switch on the power electronics. When the bit has the
value 0, the drive is not ready to switch on the power electronics. When the bit has the value 1, the
drive is ready to switch on the power electronics.
Bit 1: Readiness to operate
This bit indicates whether the drive is ready to begin operation. When the bit has the value 0, the
power electronics is switched off and the drive is unable to begin operation. When the bit has the
value 1, the power electronics is switched on and the drive can begin operation if requested by the
master.
