Fig. 8.2−21 Signal sequence with DC injection braking
0 Actual speed value of the motor (e. g. MCTRL−NACT)
1 Controller output current (e. g. MCTRL−IACT)
2 Pulse inhibit (e. g. DCTRL−IMP)
3 Activating DC injection braking (MCTRL−GSB)
4 DC injection braking is active (MCTRL−GSB−OUT)
MCTRL−GSB−OUT = HIGH: Function is active
MCTRL−GSB−OUT = LOW: Function is not active
 The motor rotates with the preset speed. The current adjusts itself as a
function of the load 5.
‚ DC injection braking is activated with MCTRL−GSB = HIGH. Pulse inhibit c
is set. The motor coasts.
ƒ The pulse inhibit is deactivated and the DC braking current set in C0036 is
injected
„ DC injection braking is deactivated with MCTRL−GSB = LOW
The motor is accelerated to speed setpoint at the set acceleration ramp and
is kept there.
