This read-only property queries the drive status. The drive status is returned every SERCOS communication cycle and comprises 32 bits. Following are the most important bit descriptions.
Bit 29- Data invalid:
0: motion bus data is valid
1: motion bus data is not valid - corrupted or missing
Bit 15 - Drive high power. 1 - high power on
Bit 14 - Drive status - 1 enabled, 0 disabled
Bit 13 - Drive Shutdown - Error in C1D
Bit 12 - Change bit for C2D (SERCOS only)
Bit 11 - Change bit for C3D (SERCOS only)
Bits 10, 9, 8 Actual operation mode (SERCOS only)
0 0 0 Primary operation mode (defined by S-0-0032)
0 0 1 Secondary operation mode 1 (defined by IDN 33)
0 1 0 Secondary operation mode 2 (defined by IDN 34)
0 1 1 Secondary operation mode 3 (defined by IDN 35)
Bit 7 - Real-time status bit 2 (SERCOS only)
Bit 6 - Real-time status bit 1 (SERCOS only)
Bit 5 - Procedure command change bit (SERCOS only)
Bit 4 - Parameterization levels (PL1, PL2) (SERCOS only)
0 - PL1 and PL2 not active .
1- PL1 or PL2 active
Bit 3 - Status command value processing .
0 - Drive ignores the command values (e.g., during Halt drive, drive controlled functions, programmed delay times)
1 - Drive follows the command values
Bit 2 - Error in service channel (SERCOS only)
Bit 1 - Busy (SERCOS only)
0 Step finished, ready for new step
1 Step in progress, new step not allowed
Bit 0 - AHS . 0/1 Service transport handshake of the drive (SERCOS only)

Scope
Configuration, Task or Terminal
Limitations
Read only.
SERCOS: Valid only in SERCOS communication phase 4.
EtherCAT: Valid only in OP mode.
Bits 0,1,2,4,5,6,7,8,9,10,11,12 are applicable only to SERCOS
EtherCAT/CANopen:
Bit 13: reflects state of bit #4 of status word (object 0x6041 subindex 0) and only if that object is mapped to PDO.
Examples
?a1.dstat
If (a1.dstat band 2^14) Then ‘Check whether the drive is enabled
