FM 453 positioning module Siemens

Область применения

The FM 453 is an intelligent, three-channel module designed for a wide range of positioning tasks using servo and/or stepper motors.

It can be used for simple point-to-point positioning tasks as well as for complex traverse profiles with the most stringent demands for dynamic response, accuracy, and velocity.

It is the ideal solution for positioning tasks in machines with high clock rates and for multi-axis machines

The FM 453 is designed for up to 3 independent servo and/or stepper motors and can be used with infeed, positioning, setup, and transport axes (linear and rotary axes) in:

• Machine tools, printing, paper, textile and packaging machines
• Handling, feeding and installation equipment

Обзор

• Positioning module for servo and/or stepper motors in machines with high clock-pulse rates
• Can be used for simple point-to-point positioning and for complex traversing profiles
• Up to 3 independent motors can be controlled

Note:

We offer position measuring systems and preassembled connecting cables for counting and positioning functions under SIMODRIVE Sensor or Motion Connect 500.

Дизайн

A positioning controller with the FM 453 features the following essential components:

• FM 453:
  • For positioning up to 3 servo and/or stepper motors
• SIMODRIVE 611A/SIMOSTEP:
  • For the power activation of the servo/stepper motors
• S7-400 CPU:
  • For sequence control
  • For starting and stopping positioning actions
• Programming device:
  • For programming the STEP 7 program
  • For parameterizing the FM 453 with STEP 7 via parameterization screen forms
  • For testing and startup
• Operator panel:
  • For operator control and monitoring of the machine
  • For error diagnostics

Функции

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.
