2.13 External brake
A mechanical spring-loaded brake fitted to the motor (disc or spring-applied
brake) brakes the rotation of the motor shaft if the brake coil’s supply voltage
is switched off. If quick brake engagement times are required, DC air soleno-
ids are used. In this case, the brake is supplied with AC power through a
functional rectifier built into the motor.
RAMO5 and RASP5 Rapid Link 5 modules feature a fast, internal electronic
switch for powering and actuating the external motor brake. It is connected
using pin 4 and pin 6 of the motor feeder socket. The highest permissible
continuous holding current is 0.6 A. For releasing the brake, up to 6 A are
available for up to 120 ms.
The brake is actuated
•
Automatically with the Start command in Auto and Manual modes in
RAMO5,
•
With RASP5 via the frequency converter.
