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