6.2 Positioning mode (P0700 = 3, from SW 2.1)
The following functions are available in the ”positioning” mode:
Referencing or adjusting
– Referencing for incremental positioning measuring systems
– Adjusting absolute position measuring systems
– Set reference point
Programming and selecting traversing blocks
The max. 64 traversing blocks per drive can be freely programmed
and are saved in the parameters.
– How many blocks can be individually selected via terminals?
Drive A + optional TERMINAL module: all 64 blocks
Drive B: Block 0 or 1 can be selected (1 input terminal)
– How many blocks can be individually selected via PROFI-
BUS–DP?
Drives A and B: all 64 blocks
A block contains the following information:
– Block number
– Item
– Velocity
– Acceleration override
– Deceleration override
– Command
– Command parameters
– Mode: Block change enable – positioning mode – IDs
When programming a traversing block, the block enable condition is
specified. This means that when starting a block, precisely one
block can be executed (for a block enable condition END) or auto-
matic, even for several blocks (if the block enable condition CON-
TINUE FLYING, CONTINUE WITH STOP, CONTINUE EXTER-
NAL).
The blocks are executed according to the consecutive block number
up to the block with the block enable condition END.
Position–related switching signals (cams)
Signals are generated and output as a function of the actual position
actual value and parameter setting.
Jogging
This operating mode allows speed–controlled traversing in the ”posi-
tioning” mode. From SW 4.1, the drive can be jogged in the closed–
loop position controlled mode (incremental) (refer to Chapter 6.2.9).
Monitoring functions
Dynamic following error monitoring, positioning monitoring, standstill
monitoring, hardware/software limit switches
