Description of I/O’s functionality
I/O Param Funktion
DI1 COAST. Closed-circuit principle, must be closed for operation.
COAST is the fastest way to stop the current controller. The current controller will decrease the
armature current to zero as fast as possible. This command will stop the drive so that the motor is
left running and friction together with the load will decrease the speed to zero.
DI2 not used
DI3 External fault signal. Triggers a fault response and trips the drive
DI4 2.01 External alarm signal. Triggers a warning in DCS400
DI5 Emergency stop. Closed-circuit principle, must be closed for operation.
In case of Emergencey stop the drive will be changed to speed control and stopped the drive in
according to parameter Eme Stop Mode (2.04)
DI6 Reset. Faultacknowledgement, reset faults signaled by the drive
DI7 Drive ON / OFF. DI7=0=OFF , DI7=1=ON
DI8 Drive START / STOP. DI8=0=STOP , DI8=1=START.
In case of STOP command the drive will be changed to speed control and stopped the drive in
according to parameter Stop Mode (2.03).
DO1 6.11 Ready for Run. Converter switched ON, but not yet STARTed
DO2 6.12 Running. Drive is STARTed (Current controller enabled)
DO3 6.13 Zero-speed signal. Motor at standstill
DO4 6.14 Group fault signal. Common signal for all faults or alarms
DO5 6.15 Main contactor on. Controlled by ON command (DI7)
