NOTE

The response when a position limit is reached (
P 2235 - MPRO_
402_SoftwarePosLimit
) will depend on the error response that
has been configured (

"Error r
eactions
" on page

).


If the DC link voltage value falls below the value set in
P 747[0] - MON_PF_
OnLimit
, error "ERR-34 Power failure detected" will be signalled and the
configured error response will be triggered (
see Section
"Error re
actions
" on
page 26
6
).

By configuring a quick stop (as an error response with a sufficiently steep
deceleration ramp), the DC link voltage can be maintained above the
undervoltage threshold (
see Section
"Power failure bridging" on page 28).
This reaction lasts until the drive has been braked to a lower speed.
