FunctionTrigger
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 brake holding load set in 0x2820:008 (P712.08) is build up via the ramp set in 0x2820:013 (P712.13).
③
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.
④
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).
⑤
In case the direcon of rotaon reverses, the holding brake remains released.
⑥
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.
⑦
Then the holding brake is closed again.
⑧
Aer the closing me 0x2820:002 (P712.02) has elapsed, the brake status "Acve [0]" is displayed in 0x2820:015 (P712.15).
The brake holding load is reduced again via the ramp.
