7.4.1.3 Enable operation
From all states
Power section inhibited (pulse inhibit)
Power section enabled
This command serves to enable the operation
and stop an active quick stop again.
• A changeover to the "Operation enabled
"
device status takes place.
• The output stages of the servo inverter are
activated.
Bit pattern for the "Enable operation" command in the Controlword (0x6040 or 0x6840 for axis B):
Bits 15 - 8 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
Fault reset Control bits depending on the operating mode Enable

Note!
The signalling of the "Operation enabled" device status in the CiA402 status word can be
delayed in the following cases:
• If in case of the synchronous motor servo control the "pole position identification
option has been activated before the start in 0x2C63
(or 0x3463 for axis B) and is just
running (few milliseconds).
• If the brake is in the "control via device state machine" mode and the brake opening
time (0x2820
or 0x3020 for axis B) has not elapsed yet.
• If an asynchronous motor is used which has not been magnetised yet.
Check the setting of the rated motor current (0x6075
or 0x6875 for axis B) and the
maximum device current (0x6073
or 0x6873 for axis B).
Only when the "Operation enabled
" device status is signalled in the CiA402 status word,
the points mentioned before are concluded and the i700 servo inverter is ready for the
acceptance of setpoints of the Controller.
