Emotron AB 01-3694-01r2 Functional Description 91
Fig. 77 shows the relation between the four Brake functions.
• Brake Release Time [33C]
• Start Speed [33D]
• Brake Engage Time [33E]
• Brake Wait Time [33F]
The correct time setting depends on the maximum load and
the properties of the mechanical brake. During the brake
release time it is possible to apply extra holding torque by
setting a start speed reference with the function start speed
[33D].
Fig. 77 Brake Output functions
Release Speed [33D]
The release speed only operates with the brake function:
brake release [33C]. The release speed is the initial speed ref-
erence during the brake release time.

Brake Engage Time [33E]
The brake engage time is the time it takes to engage a
mechanical brake.
