4.1.5
Enable/Inhibit controller
The
= "1: On / start" device command enables the controller, provided that no other
source of a controller inhibit is active.
The
= "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
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
, the flying restart function parameterised in
is used for the synchronisation to the rotary or standing drive.
• 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.
•
provides a bit coded representation of all active sources/triggers of a controller
inhibit.
4.1.6
Activate/deactivate quick stop
The
= "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
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
.
The
= "0: Off / ready" device command deactivates the quick stop again, provided that
no other source of a quick stop is active.
Tip!
displays a bit code of active sources/causes for the quick stop.
