ABB 70EA05A-E HESG447419R1 Normal DC board

Description

Beside On / Off and Start / Stop the drive is equipped with two additional stop functions Off2 and

Off3 according to Profibus standard.

Off3 is scalable via 21.03 Emergency stop mode to perform a stop according to category 1. Connect

this function to the E-stop push button (off3) without any time delay. In case of 21.03 Emergency stop

mode = Ramp stop the timer relay (K15) must be set longer than 23.23 Emergency stop time. For

21.03 Emergency stop mode = Coast stop the drive opens the mains contactor immediately.

Off2 switches the DC current off as fast as possible and prepares the drive to open the mains

contactor or drop the mains supply. For a normal DC motor load the time to force the DC current to

zero is below 20 ms. This function should be connected to all signals and safety functions opening

the mains contactor. This function is important for 4-Q drives. Do not open mains contactor during

regenerative current. The correct sequence is:

1. Switch off regenerative current.
2. Then open the mains contactor.
