Description
Sets the braking strength, choose suitable
value for application.
Sets the motor brake time.
Sets the Dynamic braking strength.
Sets the DC braking strength.
The approximate speed when the switch from
dynamic brake to DC brake occurs.
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.
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
Enables dynamic optimization of dynamic
brake
Enables additional thyristor trig occasions of
dynamic brake
Flux threshold for thyristor trig of dynamic
brake
Flux threshold for speed estimation of
dynamic brake
