Setup: Position-controlled traversing of the axes at the touch of a button
Incremental feed: Position-controlled traversing of permanently selectable paths
MDI (Manual Data Input)/MDI on-the-fly: Position-controlled positioning to any positions that can be entered
Automatic follow-on block/single block: Position-controlled traversing of complex positioning profiles; continuous/step by step, forwards/backwards.
Special functions
e.g.,
Longitudinal measuring
Start and stop positioning runs via the fast input of the FM 354
Jerk limitation
Set actual value on-the-fly
Mode of operation
The user must perform the following steps in preparation:
Coordination of mechanical system and electronics: Easily achieved by entering machine data using the parameterization software (configuring package is included in the scope of supply of the FM).
Specify traversing path;
For simple point-to-point positioning: Specify end position and traversing speed via the S7 CPU.
For more complex tasks: Traversing programs, created with parameterization screen forms to DIN 66025 on a programming device or in teach-in mode.
The FM 354 handles the actual positioning of the axis. The drive is controlled via the analog drive interface (-10 to +10 V). Encoders (SSI or incremental) report the current axis position. The FM 354 changes the output voltage in accordance with the encoder signals.
