①
If the inverter is enabled and no error is acve, the motor can be started with the "Run" funcon in forward rotang direcon.
The power secon is switched on and the motor is magnesed rst.
②
The holding brake is released. For this purpose, the output trigger "Release holding brake [115]" is set to TRUE. This trigger must be
assigned to a digital output or, in the simplest case, to the relay which then switches the brake supply.
③
Aer the release me 0x2820:003 (P712.03) has elapsed, the motor is accelerated to the setpoint.
The brake status "Brake released [1]" is displayed in 0x2820:015 (P712.15).
④
If the direcon of rotaon reverses, the holding brake remains released (even if the closing threshold delay is running.)
⑤
If the setpoint selecon and the internal setpoint for the motor control fall below the brake closing threshold set in 0x2820:007 (P712.07),
the output frequency is ramped down to "0 Hz".
At the same me the closing threshold delay set in 0x2820:012 (P712.12) starts to run
⑥
If the values fall below the closing threshold longer than the closing threshold delay, the holding brake is closed again.
⑦
Aer the closing me 0x2820:002 (P712.02) has elapsed, the brake status "Acve [0]" is displayed in 0x2820:015 (P712.15).
⑧
If "Run" is set to FALSE, the motor is stopped with the stop method set in 0x2838:003 (P203.03). In the example: Stop with standard ramp.
In this case, closing threshold and closing threshold delay are not eecve anymore.
