SIMATIC S7-300
Function modules
1FL3 stepper motors
■ Overview
■ Technical specifications
4
Stepper motors are functionally simple servomotors.
In terms of performance and economy, these motors are the
ideal supplement to the position controlled motors 1FT and 1FK.
The applications in automation systems are varied, and are not
restricted to machine tools.
The SIMOSTEP stepper motor can be operated via the
FM STEPDRIVE power section. This converts the stepping and
direction signals of the upstream controller into exact angular
movements by appropriate current feeding to the motor
windings.
SIMOSTEP 1FL3 with holding brake (optional)
The holding brake normally fixes the position after the motor
current has been switched off. In emergencies, such as after
power failure or EMERGENCY STOP, it stops the drive and thus
helps to maintain safety. Fixing is mainly required in case of
torque load resulting from weight forces, e.g. Z axes in robotics
(vertical axis).
