19-06 Error behaviour
Option:
Function:
[0]
*
Electronic brake
This parameter determines the behaviour of the drive after an
error is detected.
If “0” is selected the drive will ramp down to standstill with the
shortest possible ramp (P3281). After achieving standstill it will
activate the electronic brake according to the setting of COAST
DELAY. If the drive is coasted at any point during ramp down
(e.g. due to an OVER CURRENT trip) the drive will immediately
activate the brake and coast the drive.
[1]
Mechanical brake
If “1” is selected the drive will immediately activate the brake
and coast the drive.
The brake is always activated after an error situation (or quick stop) regardless of
the AUTO BRAKE CTRL setting.
19-07 Error reset
Option:
Function:
[0]
*
No reset
The parameter automatically resets to “0” when the error is
successfully cleared.
[1]
Reset error
By setting this parameter to “1” it is possible to clear the error
flag (provided that the reason for the error is not still present).
19-08 Power-recovery
Option:
Function:
[0]
disabled
When the power recovery function is disabled (0), it is not pos-
sible to drive the application by any means (neither jogging nor
positioning) as long as the application is outside the HW or SW
limits. The only way to recover from this situation is to move the
application by hand.
[1]
*
enabled
When the power recovery function is activated (1) however it is
possible to make a “partial reset“ of the limit error (ERROR STA-
TUS = 2/3/4/5) whereby it will be possible to use the jogging
function to drive the application out of the HW or SW limit area.
It is not possible to drive the application otherwise by means of
homing, positioning or jogging (in the wrong direction), as long
as the application is still within the HW or SW limit area. The
“error occurred” output will remain high to indicate that these
restrictions are in effect. As soon as the application is moved
outside the HW or SW limit area the error is automatically
cleared and the “error occurred” signal goes low to indicate that
normal operation is now restored.
