Operation

ACS800-07 units with line contactor

The category 0 emergency stop, i.e. immediate removal of power, operates as
follows.
The DSSB board receives an emergency stop command, i.e.
The ±24 VDC power supply circuit
for the diode supply module main
contactor control on the DSSB
board is deactivated.
The line contactor opens.
Diode supply unit trips on a fault.
Fault LED OTHER FAULT,
EMERGENCY STOP on the DSSB
board keeps lit.
RMIO = motor control and I/O board (control board for the inverter unit)
A21
DSSB = Diode Supply System Board (control board for the rectifier unit)
Category 0 emergency stop for ACS800-07/17/37 (+Q951, n×R8i)
The user presses the emergency stop push-button.
0 V to input X8:1–X8:2.
Fault LED OTHER
STOP on the DSSB
board illuminates.
= safety relay
FAULT,
EMERGENCY
Digital output RO5 on the DSSB
board is deactivated deactivating
