• 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.
