7 Braking operation

The 9400 HighLine controller as single-axis controller (single drive) is provided with an integrated

brake transistor.

• The required brake resistor must be connected externally (see Mounting Instructions/Hardware

Manual).

• The rated values for the internal brake transistor are given in the Hardware Manual in the

chapter "Rated data".

 Stop!

If the brake resistor actually connected is smaller than the brake transistor

parameterised, the brake chopper can be destroyed!

The brake resistor can be thermally overloaded. Carry out protective measures suitable

for the installation, e.g.:

• Parameterisation of an error response in C00574

and evaluation of the parameterised

error message within the application or within the machine control. I2t utilisation

• External interconnection using the thermal contact on the brake resistor (e.g. supply

interruption via the mains contactor and activation of the mechanical brakes).

 Note!

The brake chopper control is also guaranteed if, for example, the application stands still

or the 24-V supply is not connected and the controller is only fed by the DC bus.
