Functional Description
CG Drives & Automation, 01-5326-01r5
The Brake Release Time sets the time the AC drive delays
before ramping up to whatever final reference value is
selected. During this time a predefined speed can be
generated to hold the load where after the mechanical brake
finally releases. This speed can be selected at Release Speed,
[33D]. Immediate after the brake release time expiration the
brake lift signal is set. The user can set a digital output or
relay to the function Brake. This output or relay can control
the mechanical brake.
Communication information
Fig. 103 shows the relation between the four Brake
functions.
•
Brake Release Time [33C]
•
Release 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 release speed reference with the function release
speed [33D].

NOTE: Although this function is designed to operate a mechanical brake via the digital outputs or relays (set to brake
function) controlling a mechanical brake, it can also be used without a mechanical brake and hold the load in a fixed
position.
