P064 Filtering Time over AIN2 Input
P064
Range
0 ÷ +65000
0 ÷ +65000ms
Default
5
5 ms
Level
ADVANCED
Address
664
Function
This parameter selects the value of the filter time constant of the first command
applied to AIN2 input signal when the signal saturation and conversion is over.
P065 Minimum Reference and START Disabling Threshold
P065
Range
0 ÷ +32000
0 ÷ +32000 rpm
Default
0
0rpm
Level
ADVANCED
Address
665
Function
If this parameter is other than zero, the current speed reference computed when
processing of all active source references is over,
it is saturated as an absolute
value of this parameter’s value.
Saturation implies an absolute value, i.e. this parameter determines a “prohibit
range” of the reference approx. zero.
Example:
P065 = 100 rpm and current speed reference is 500 rpm; if reference drops below
100 rpm, for example down to +50rpm, the value of the active reference is saturated
to 100 rpm until reference exceeds 100 rpm again or is lower than -100 rpm; in that
case, the preset value will be assigned to the reference.
If also parameter P066 is other than zero, the drive disabling function is enabled
:
if the absolute value of the current speed reference is kept in the “prohibit range”
for
a time longer than the time set in P066
, reference is set to zero and the motor speed
decreases following the active ramp up to zero rpm; when the motor speed is equal
to zero, the drive will automatically deactivate.
With ENABLE-A and ENABLE-B inputs closed, the
drive will automatically
reactivate if the reference exceeds the value set in parameter P065
as an absolute
value.
NOTE
Parameter P065 is active in Master mode only, i.e. when the reference is a direct speed
reference not sent from PID with C294 PID Action = 1:[Reference]).
NOTE
Parameter P065 is active only when the Speed searching and Power Down functions are
disabled: C245=0 and C225=0.
P066 START Disable delay at P065 Threshold
P066
Range
0 ÷ 250
0 ÷ 250 sec
Default
0
0: Disabled
Level
ADVANCED
Address
666
Function
If this parameter is other than zero and if also parameter P065 is other than zero, the
drive disabling function is enabled
: if the absolute value of the current speed
reference is kept in the “prohibit range” for a time longer than the time set in P066
,
reference is set to zero and the motor speed decreases following the active ramp up
to zero rpm; when the motor speed is equal to zero, the drive will automatically
deactivate.
