Function
Type of power down:
0: Disabled The Power Down function is disabled.
1: Yes In case of mains loss after a ti
me longer than the time set in
C226 starting from the mains loss detection, the deceleration ramp set in C227
is
performed.
2: YesV
In case of mains loss, deceleration is automatically regulated by
a PI regulator (see C231 and C232), so that vo
ltage level in DC link is kept
constant at the reference value set in C230.
IFD control: because no torque demand regulation is available, the deceleration
ramp gradient is adjusted depending on the gradient value set in C227.
3: Alarm In case of power failure, the A064 Mains Loss alarm trips
after
the time set in C226.
NOTE
If a drive is DC-powered by a Regenerative Penta (or an equivalent drive
stabilizing DC
bus voltage), Power Down cannot occur (C008 = xT Regen, where x can be 2, 4, 5, or 6 ).
