Æ’ After a signal, the motor is braked by injecting a DC current.
Æ’ Braking in generator mode must be used for controlled brake ramps.
Æ’ The hold time (C0107) has no influence. The motor remains braked
until MCTRL−GSB is set to LOW.
 Note!
Manual DC injection braking has priority over quick stop.
Special features of vector control with feedback
ƒ If the DC braking current (C0036) £ than the motor magnetising current,
the motor magnetising current is injected.
Æ’ If the DC braking current (C0036) > than the motor magnetising current,
the DC braking current is injected.
Setting
Selection Code Description
DC braking current C0036 DC braking current with which the motor is braked
 Stop!
An excessive DC braking current and braking time can thermally
overload the motor. Special care must be taken when using
self−ventilated motors.
Activation
The input MCTRL−GSB in the function block MCTRL is triggered with HIGH
level.
ƒ MCTRL−GSB = HIGH: Function is activated
ƒ MCTRL−GSB = LOW: Function is not activated
