Motor braking has these parameters:
Parameter Description Setting range Default value
07.01 Stand still brake strength Sets the braking strength, choose suitable
value for application.
10 – 100% 50%
07.02 Motor brake time Sets the motor brake time. 1.0 – 100.0 s 1.0 s
07.03 Dynamic brake strength Sets the Dynamic braking strength. 10-100% 40%
07.04 DC brake strength Sets the DC braking strength. 10-100% 40%
07.05 DC brake switch speed
threshold
The approximate speed when the switch from
dynamic brake to DC brake occurs.
10-100% 28%
07.06 DC brake switch delay time Sets the time that the speed has be below
the threshold before the switch to DC brake
occurs. Configure this parameter only if the
switch occurs too soon or too late.
0.1 – 100.0 s 3.0 s
02.02 Stop mode Sets the desired stop mode: No ramp =
Immediately cuts power to the motor, Voltage
stop ramp = Decreases voltage linearly,
Torque stop ramp = Decreases torque in a
pre-defined pattern, Dynamic brake = Applies
brake to the motor
No ramp/Voltage stop ramp/
Torque stop ramp/Dynamic
brake
No ramp
28.51 Firing angle sweep Enables dynamic optimization of dynamic
brake
Off, On On
28.52 Auxiliary condition Enables additional thyristor trig occasions of
