4.1.5

Enable/Inhibit controller

The

C00002/16

= "1: On / start" device command enables the controller, provided that no other

source of a controller inhibit is active.
The

C00002/16

= "0: Off / ready" device command inhibits the controller again, i.e. the power out-

put stages in the controller are inhibited and the speed/current controllers of the motor control are

reset.

• The motor becomes torqueless and coasts down.
• When the controller is inhibited, the status output bCInhActive of the

LS_DriveInterface

system

block is set to TRUE.

• When the controller inhibit request is reset, the drive synchronises to the actual speed. For this

purpose,

• If the flying restart circuit is activated in

C00990

, the flying restart function parameterised in

C00991

is used for the synchronisation to the rotary or standing drive.

tion

( 148)

• In the case of an operation with feedback, the actual speed is read out by the encoder system.

Tip!

• The controller can also be enabled or inhibited via the

and

toolbar icons.

C00158

provides a bit coded representation of all active sources/triggers of a controller

inhibit.

4.1.6

Activate/deactivate quick stop

The

C00002/17

= "1: On / start" device command activates the quick stop function, i.e. the motor

control is separated from the setpoint selection, and within the deceleration time parameterised

in

C00105

the motor is brought to a standstill (n

act

= 0).

• The motor is kept at a standstill during closed-loop operation.
• A pulse inhibit (CINH) is set if the auto-DCB function has been activated via

C00019

.

The

C00002/17

= "0: Off / ready" device command deactivates the quick stop again, provided that

no other source of a quick stop is active.

Tip!

C00159

displays a bit code of active sources/causes for the quick stop.
