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 controller become

active.

Bit pattern for the "Enable operation" command in the Controlword (

0x6040

or

0x6840

for axis B):

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.
