Category
OFF functions
Function
This function allows the drive to be stopped using the function quick stop (OFF3) along a
deceleration ramp to be parameterized by the user. The energy feed to the converter is then
interrupted (armature circuit and field circuit) via the main contactor or via the circuit-breaker,
bypassing the microprocessor controller of the drive using a safety relay. It must be ensured
that this type of switch off does not represent any danger.
3TK2827 and 3TK2830 safety relays are used with a 24 V DC supply voltage.
