Macro variables for debugging
SERC_SYNCVAL Synchronization time T3 in µs
SERC_NOSYNC
Synchronization deviation in µs
SERC_SYNCHUB Stroke used for the PWM
SERC_VVOR
Pilot speed control value IDNP 3055
SERC_IVOR
Pilot speed control value IDNP 3056
SERC_SOLLFREI
Internal release of the target values from the interpolator. Determin-
ed by functions such as homing or "wake & shake" and of course
also by the control bits.
SERC_SOLL-
WERT
Target value of the control system via sercos
®
(formerly
DPRNEW30)
S_SETH
Target value of the linear interpolation. However, this value is only
applied when OPMODE is 6 and SERC_SOLLFREI is 1.
S_SETL
Target value of the position controller
HARDENA
Hardware enable
SOFTENABLE
Software enable
EN_P_I
Global enable of the output stage, consisting of software and hard-
ware enable.
OPMODE
Operating mode 6 = sercos position control
PFB
Actual position value of motor encoder
PFB0
Actual position value of external encoder
PRD
Commutation angle
S_FEHL
Internal tracking error
TRJSTAT
Collective bit variable for the trajectory status
SERC_ATSTAT
AT status word
SERC_MDTCNTL MDT control word
STATCODE

®
bus
TICK0
Counter 62.5µs
TICK
Millisecond counter
TICK250
