No.
632 Braking time
To avoid current surges, which can possibly lead to a fault switch-off of the frequen-
cy inverter, a direct current may only be impressed into the motor after the motor
has been demagnetized. As the demagnetization time depends on the motor used, it
can be set with the parameter
The selected demagnetizing time should be approximately three times the

No.
633 Demagnetizing time
The selected stopping behavior is supplemented by a current controller to control the
direct current brake. The PI controller checks the current impression of the set

WARNING
Comply with standard EN 60204 and VDE provision 0100 part 227 and provision
0113, in particular Sections 5.4, protection against automatic restart after main line
voltage failure and voltage recovery, and Section 5.5, undervoltage protection.
Appropriate measures must be taken to exclude any risk for staff, machines and pro-
duction goods.
In addition to that, all specific regulations relevant to the application as well all na-
tional directives are to be complied with.
The Auto Start function is suitable for applications which permit a start at mains volt-
age by their function. By activation of the auto-start function via parameter

according to the regulations. When the motor is switched on, it is accelerated accord-
ing to the parameterization and the reference value signal.
