Command Description

COMMAND 2, 6, 8 (standstill)

Control word: bit 0 = 0

Command to change from different device status to the READY TO

START status.

COMMAND 3 (switch on) Command to change to the SWITCHED ON device status.

COMMAND 4 (enable operation) Command to change to the OPERATION ENABLED device status. The

controller inhibit is deactivated.

COMMAND 5 (inhibit operation) Command to change to the SWITCHED ON device status. Controller

inhibit is activated.

COMMAND 7, 9, 10, 12 (voltage inhibit)

Control word: bit 1 = 0

Controller inhibit is activated.

COMMAND 7, 10, 11 (quick stop)

Control word: bit 2 = 0

Command to change to the SWITCH−ON INHIBIT device status. If the

drive was enabled, a controlled deceleration (quick stop deceleration

ramp) is executed.

COMMAND 13 (fault/TRIP) The controller has detected a fault. Some faults require a controlled

deceleration (device−dependent). When it is completed, the device

status changes to FAULT.

COMMAND 14 (reset fault/TRIP)

Control word: Bit 7 = 0  1

In the case of the 821X, 8200 vector device series, this command resets

a fault. The controller changes to the SWITCH−ON INHIBIT device status

when a fault has been eliminated.
