HEIDENHAIN iTNC 530 HSCI - Meanings of the Signals under Status; Position Controller

1314 HEIDENHAIN Technical Manual iTNC 530 HSCI
Meanings of the
signals under
"status / position
controller"
Signal Meaning Colors
Position control loop
closed
Corresponds to PLC word W1024/W1100
for a specific axis. Information about
whether the position control loop is
closed or open.
 Gray: No information about
the signal available
 Green: Position control loop
closed

Red: Position control loop open
Position-controlled The signal indicates whether the axis is
operated with position feedback control
or speed feedback control.
 Gray: No information about
the signal available
 Green: Axis is operated with
position feedback control
 Red: Axis is operated with
speed feedback control
Nominal position value
filter
The signal indicates whether the nominal
position value filters are active.
 Gray: No information about
the signal available
 Green: Nominal position
value filter is active
 Red: Nominal position value
filter is not active
Position controller
limit
The signal indicates whether "eliminate
following error" is active.
 Gray: No information about
the signal available
 Green: Output limit is active

Red: Output limit is not active
CC monitoring active The signal indicates whether following-
error monitoring is active (can be
deactivated by PLC, W1042/W1136).
 Gray: No information about
the signal available
 Green: Following-error
monitoring is active
 Red: Following-error
monitoring is not active
Touch probe is active The signal indicates whether probing is
active.
 Gray: No information about
the signal available
 Green: Probing is active
 Red: Probing is not active
Reference pulse active The signal indicates whether the MC
expects a reference pulse (host
command).
 Gray: No information about
the signal available
 Green: Expectation of
reference pulse is active

Red: Expectation of
reference pulse is not active
Velocity feedforward
control
The signal indicates whether the position
controller is working with feedforward
control or with following error.
Acceleration feedforward control can be
switched on/off cyclically by the MC.
Corresponds to parameter MP1392 or
MP1391.0 in the MP file, depending on
the current mode of operation.
 Gray: No information about
the signal available
 Green: Operation with
feedforward control
 Red: Operation with
following error
