2.16 MECHANICAL BRAKING
The FASTACT series motors have an optional electromagnetic brake with pressure springs
to be supplied with 24 V
dc
nominal voltage (24 to 26 V
dc
) at the motor terminal.
CAUTION: the brake must be used only for standing (with motor at standstill). The use of this
brake for dynamic braking seriously damages the brake and reduces the braking torque.
