4.4.3 Control of motion
4.4.3.1 Selection of motion block via digital signals (motion
block change-over)
If the motion blocks are selected via digital signals, motion blocks 1 to 32 can be
selected via the motion block change-over function.
The motion block selection via digital inputs is active if parameter
Operation Mode
1221 is set to one of the following modes:
− 101 - Sequence Mode w/o Restart, 1st Motion Block via Digital Inputs
− 111 - Sequence Mode with Restart, 1st Motion Block via Digital Inputs
− 201 - Single Motion, Motion Block Sel. via Digital Inputs
− 301 - Teach-In, Motion Block Sel. via Digital Inputs
In operation modes 101, 111 and 201, the motion starts with the motion block se-
lected via the digital inputs when a signal is present on the input for
Start Position-
ing
1222.
In operation mode 301, the current position is saved as the
Target Position / Dis-
tance
1202 in the motion block selected via the digital inputs when a signal is pre-
sent on input for
Teach-In-Signal 1239.
