General mode of operation
The following diagram demonstrates the general functioning of the automatic operation:
① If the inverter is enabled and no error is active, the motor can be started with the
"Run" function in forward rotating direction.
The power section is switched on and the motor is magnetised first.
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 After the release time 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 "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.
⑤ Then the holding brake is closed again.
⑥ After the closing time 0x2820:002 (P712.02) has elapsed, the brake status "Active
[0]" is displayed in 0x2820:015 (P712.15).
If the power section is disabled, the holding brake is closed. Reasons for this
can be an error, a fault, or the activation of the "Safe torque off (STO)" safety
function.
