Function
8 bytes are available for data communication with the drive controller.
Byte Notes Address
1, 2 Bytes 1 and 2 form the control word for the controller.
The signals for functions such as IMP, CINH etc. can be written from SB DCTRL to the SB CAN1_OUT by
using the status word from SB DCTRL. To do this, connect the variables
DCTRL_wStat and
CAN1_wDctrlStat .
Several bits in SB DCTRL are freely assignable. They are configured through the variables
DCTRL_bStatB0_b , DCTRL_bStatB1_b , DCTRL_bStatB2_b , DCTRL_bStatB3_b , DCTRL_bStatB4_b ,
DCTRL_bStatB5_b , DCTRL_bStatB14_b and DCTRL_bStatB15_b
%QB31.0 and %QB31.1
3, 4 You can freely link bytes 3 and 4 with variables of the corresponding data type, as a 16-bit data word
(quasi-analog signal).
%QB31.2 and %QB31.3
5, 6
It is possible, using different variables, to write simultaneously to bytes 5-6 or bytes 7-8. Avoid this

Example: If you write to bytes 7-8, using the variables CAN1_nOutW3_a and CAN1_dnOutD1_p then bytes 7-8 will be rewritten every time a
variable is processed. The data in bytes 7-8 are thus not unambiguous.
