Stopping the deceleration ramp function generator
The deceleration ramp function generator is stopped for a short time if the voltage threshold for braking operation is exceeded.
Details
When this braking method is selected, the maximum permissible time for the deceleration override has to be set in 0x2541:005 (P706.05).
–
If the DC-bus voltage does not fall below the voltage threshold for braking operation shown in 0x2541:002 (P706.02) within this time, the motor is decelerated further.
–
The time is only reset if the voltage threshold shown in 0x2541:002 (P706.02) is not reached.
Precondition
The "inverter motor brake" braking method only works in operating mode 0x6060 (P301.00) = "MS: Velocity mode [-2]”.
