Figure 5: Drive with holding brake of the L-412
The drive comprises the following subassembly or subassemblies:
Motor
The motor generates the force required to move the fixed load.
The motor of the L-412.xx9211E1 has a commutation encoder. For information on coding,
refer to
"Commutation Encoder" (p. 36) .
In the case of the L-412.xx9211E1, overheating is prevented using temperature
sensors (p. 34) .
Drive screw
The drive screw converts the rotary motion of the drive to linear motion of the motion
platform.
Rotary encoder
The rotary encoder measures the motor shaft's angle of rotation. This signal can be used by
suitable electronics for commutating the motor .
4.3.3 Holding Brake
For L-412.xx9211E1B models:
The holding brake blocks the drivetrain at rest.
The holding brake is designed for holding only and is not suitable for continuous braking
during operation.
The holding brake blocks in a zero voltage state.
4.3.4 Drag Chain
The drag chain (also: energy chain or energy supply chain) guides and protects the
L-412.xx9211E1's flexible cables and lines.
4.3.5 Purge Air System
The purge air system protects the drive and guides of the L-412.xx9211E1 against
