Siemens SINUMERIK 828D

Display data Meaning
Feedforward control mode Indicates whether and if so, which mode of the dynamic feedforward
control for the axis is active:
● Inactive
● Velocity
The velocity-dependent speed feedforward control is active.
● Torque
The
acceleration-dependent torque feedforward control is active (in
combination with the speed feedforward control)

"Referenced" state Status display for reference point approach (axis):
● Active MS need not be referenced
● Active MS referenced
● Active MS must be referenced
The display depends on the settings in the machine data:
●
MD34110 $MA_REFP_CYCLE_NR
● MD20700 $MC_REFP_NC_START_LOCK
The display corresponds to the NC/PLC interface signal:
DB31, ... DBX60.4 and 60.5 (referenced/synchronized 1 or 2)

QEC state Indicates whether and if so, which method of the quadrant error com‐
pensation (QEC) is active for the axis:
● Inactive
● Neural QEC learning active
● Conventional QEC active
●
Conventional QEC w. adapt. comp. value act.
(conventional QEC with adaptation of the compensation value
active)
● Neural QEC active
● Neural QEC w. ad. meas. time val. act.
(neural QEC active with adaptation of the measuring time active)
● Neural QEC w. ad. dec. time comp. val. act.
● (neural QEC with adaptation of decay time of compensation value
active)
● Neural QEC w. ad. meas. time + dec. time comp. val. act.
(neural QEC active with adaptation of measuring time and decay
time of compensation value active)
