4.8 Mechanical Brake

For hoisting applications, it is necessary to be able to
control an electro-magnetic brake. For controlling the
brake, a relay output (relay1 or relay2) or a programmed
digital output (terminal 27 or 29) is required. Normally, this
output must be closed for as long as the frequency
converter is unable to ’hold’ the motor, for example,
because of excess load. For applications with an electro-
magnetic brake, select

[32] mechanical brake control

in one

of the following parameters:

5-40 Function Relay

(Array parameter),

5-30 Terminal 27 Digital Output

, or

5-31 Terminal 29 Digital Output

When

[32] mechanical brake control

is selected, the

mechanical brake relay stays closed during start until the
output current is above a preset level. Select the preset
level in

2-20 Release Brake Current

. During stop, the

mechanical brake closes when the speed is below the level
selected in

2-21 Activate Brake Speed [RPM]

. When the

frequency converter is brought into an alarm condition
(that is, an over-voltage situation), or during safe stop, the
mechanical brake immediately cuts in.

Illustration 4.22 Mechanical Brake Control for Hoisting Applications

In hoisting/lowering applications, it must be possible to
control an electromechanical brake.

Step-by-step Description

•

To control the mechanical brake, use any relay
output, digital output (terminal 27 or 29) or solid-
state brake voltage output (terminals 122 - 123).
Use a suitable contactor when required.

•

Ensure that the output is switched off as long as
the frequency converter is unable to drive the
motor. For example, due to the load being too
heavy, or when the motor is not yet mounted.

•

Select

[32] mechanical brake control

in parameter

group5-4* (or in parameter group 5-3*) before
connecting the mechanical brake.

•

The brake is released when the motor current
exceeds the preset value in

2-20 Release Brake

Current

.

•

The brake is engaged when the output frequency
is lower than a preset limit. Set the limit in

2-21 Activate Brake Speed [RPM]

or

2-22 Activate

Brake Speed [Hz]

and only if the frequency

converter carries out a stop command.
