Positioning functionality

• Setup:
  Move the axis into position at the touch of a button (jog mode)
• Incremental feed:
  Move axes along paths already filed in a table (for example, at initial startup).
• MDI (Manual Data Input)/MDI on-the-fly:
  Positioning to any positions at any speed.
• Automatic follow-on block/single block:
  Traversing of complex positioning profiles; continuously/successive, forward/backward.

Special functions

• Longitudinal measuring
• Start and stop positioning runs via the fast input of the FM 453
• Jerk limitation
• Set actual value on-the-fly,

Mode of operation

The following preparatory steps must be carried out:

• Coordination of mechanical system and electronics:
  User-friendly input of machine data with the configuring software (in the scope of supply of the configuring package)
• Specify traversing paths:
  • For simple point-to-point positioning:
    Specify end position and traversing speed via the S7 CPU.
  • Complex traversing profiles:
    Traversing programs created with parameter screen forms acc. to DIN 66025 on the programming device or in teach-in mode

The parameterization data is stored retentively on the FM 453:

• Machine data
• Tool compensation data
• Traverse programs
• Incremental dimensions

The FM 453 handles the actual positioning of the axes. The drive interface controls the motors:

• Servo motor: -10 V to +10 V.
• Stepper motor: Pulse/direction

Encoders (SSI or incremental) report the current axis position. The stepper motor can also be operated without encoders.
