Status word 1 (ZSW1)
Table 110. Application status word PROFIdrive
Bit Value Significance Comments
0 1 Ready To Switch On Power supply is switched on, electronics initialized, main contact, if available, has dropped out,
pulses are inhibited.
0 Not Ready To Switch On
1 1 Ready To Operate Refer to control word 1, bit 0.
0 Not Ready To Operate
2 1 Operation Enabled Drive follows set point. This means, that the electronic and pulses are enabled (Refer to control
word 1, bit 3), the closed loop control is active and controls the motor and the output of the set point
channel is the input for the closed loop control.
0 Operation Disabled Either the pulses are disabled or the drive doesn’t follow the output value of the set point channel.
3 1 Fault Present Unacknowledged faults or currently not acknowledgeable faults (fault messages) are present (in the
fault buffer). The fault reaction is fault-specific and device-specific. The acknowledging of a fault may
only be successful, if the fault cause has disappeared or has been removed before. If the fault has
isolated the voltage, the drive goes into the “Switching On Inhibited” condition, otherwise the drive
returns to operation. The related fault numbers are in the fault buffer.
0 No Fault
4 1 Coast Stop Not Activated
(No OFF 2)
0 Coast Stop Activated (OFF 2) “Coast Stop (OFF 2)” command is present.
