Record control byte 1
PNU PNU: 401 Index: 1 ... 64
Max index: 64 Class: Array Data type: bitarray
Values Default: 0000 0000 0000 0000 0000 0000 0000 0000

The record control byte 1 (RCB1) controls the most important settings for the positioning task.
It corresponds to the CDIR in direct mode, see section 2.2.4).
Bit Name Description
0 (ABS) Absolute/Relative = 0: Setpoint value is absolute
= 1: Setpoint value is relative
1)
1 (COM1) Control mode 1= 0: Position control
= 1: Pressure/Force control
2 (COM2) Control mode 2 Only with position control (COM1=0):
= 0: Unassigned profile
= 1: Auto−profile
3 Reserved, must be 0
4 (VLIM) Velocity limit For force control:
value deactivated = 0: Velocity limit value active
= 1: Velocity limit value deactivated
5 (XLIM) Stroke limit value With force control:
deactivated = 0: Stroke monitoring active
= 1: Stroke monitoring deactivated
6 (FAST) Fast stop = 0: Exact stop
= 1: Fast stop
7...32 Reserved, must be = 0.
1)
The setpoint value is relative to the last setpoint value (with MC and record sequencing with condi
tion MC") or to the actual value (if MC is not present). Force tasks following position tasks refer to
force 0.
o The parameter value cannot be changed.
o Writing permissible only in commissioning/parametrising mode with disabled controller.
o This parameter can be written by FCT without higher−order controller.
o After writing, controller recalculation is carried out.
