Run command
Frequency
Current
Contracting brake
1)
Upon the receipt of run command, the drive will accelerate to the contracting brake
release frequency set by P40.06.
2)
When frequency attains the value as set by P40.06, digital output terminal "contracting
brake control" outputs OFF to control the contracting brake release.
3)
Perform constant-speed running at contracting brake release frequency. During this
period, the drive keeps the output current no higher than the current as set by P40.07.
4)
When the running time at contracting brake release frequency attains set value of
P40.08, the drive will accelerate to set frequency.
5)
Upon the receipt of stop command, the drive decelerate to contracting brake actuation
frequency set by P40.09 and maintains constant-speed running at this frequency.
6)
When the running frequency attains the set value of P40.09, waiting a period of time set
by P40.10, then digital output terminal "contracting brake control" will output ON signal
to control contracting brake actuation.
7)
When the time of output ON signal "contracting brake control" attains the set value of
P40.11, the drive will block the output and stop.
Contracting brake release
P40.06
When frequency attains this value, digital output terminal "contracting brake control" outputs
OFF signal to control the release of contracting brake. This value can be set the same value as
rated slip frequency of motor. Under V/f control, it could be set to a relatively large one.
Contracting brake release
P40.07
Current is limited to this value before the drive starts its acceleration from contracting brake
release frequency, in other words, before contracting brake mechanism is not completely
released.
