Signal status, signal description
1 Jogging 2 ON
If operation is enabled and positioning is not active ––> the
drive traverses closed–loop speed controlled with jogging
setpoint 2.
––> Refer to Chapter 5.4.1
0 Jogging 2 OFF
1 Not used or permanent 1 signal
From SW 3.0: If P701 = 1 ––> process data (PZD) are ac-
cepted
0 –
From SW 3.0:
If P701 = 1 ––> drive state is kept constant (last valid pro-
cess data with STW.10 = 1)
1 Referencing is executed
Prerequisite: Operation enabled
0 Normal operation
1 Automatic single block operation
Disables programmed path controlled operation.
Each block has to be re–started.
0 Automatic
Programmed path controlled operation is effective.
1 External block change
The active block is interrupted and the subsequent block is
selected. This is realized, dependent on the program, with
approximate positioning or precise stop.
When the block change is recognized, the position actual
value of the axis is written into P55 (signal position).
0 No external block change
1 Read–in enable
The following program block is enabled for execution.
0 No read–in enable
1 Open holding brake
The integrated holding brake can be controlled using this
signal.
The signal corresponds to P56.4 (open holding brake).
Note:
If the holding brake is controlled using an input terminal with
function number 26 (open holding brake), then this signal
has no effect.
––> Refer to Chapter 5.5.13
0 Brake sequence control effective
