02.29 : Jog deceleration rate
Adjustment range : 0.1 to 3200.0 s *
Factory setting : 0.2 s
Format: 16 bits
Sets the time for deceleration from 1000 rpm * to 0.
02.29 =
t(s) x 1000 rpm
(N2 - N1) rpm
*
02.30 to 02.49 : Not used
02.50
: Speed reference locked at motor speed
Adjustment range : No (0) or Yes (1)
Factory setting : Yes (1)
Format: 8 bits
In applications with high inertia, the actual speed does not
necessarily manage to follow the ramp reference. In this case,
on a stop command or change of reference, an idle time, linked
to the difference between the reference and the actual speed,
can occur. By enabling 02.50 , the speed and ramp are locked,
so that the idle time disappears.
02.51 : Ramp hold condition
Adjustment range : Always (0) or Speed > 01.07 (1)
Factory setting : Always (0)
Format: 8 bits
Always (0):
When 02.03 = Yes (1), the ramp is always held.
Speed > 01.07 (1):
When 02.03 = Yes (1), the ramp is freed between 0 and V min
( 01.07 ), above this speed the ramp is locked.
02.52 : Special ramp validation
Adjustment range : Disabled (0)
2 acceleration ramps (1)
2 deceleration ramps (2)
2 acceleration deceleration ramps (3)
Factory setting : Disabled (0)
Format: 8 bits
Disabled (0):
Double ramps not enabled.
2 acceleration ramps (1):
Double ramps on acceleration. From 0 to the speed defined in
02.53 , the acceleration ramp used is that defined by 02.11 to
02.19 . From 02.53 , the acceleration ramp used is defined in
02.54 .
2 deceleration ramps (2):
Double ramps on deceleration. The drive decelerates to the
speed defined in 02.53 with the deceleration ramp defined by
02.55 , then decelerates to 0 with the ramp defined by 02.21
to 02.28 .
2 Acceleration deceleration ramps (3):
Double ramps on acceleration and deceleration. The drive
accelerates or decelerates to the speed defined in 02.53 , and
the acceleration and deceleration ramps used are those
defined by 02.11 to 02.19 and 02.21 to 02.29 respectively.
From 02.53 , the acceleration and deceleration ramps used
are defined by 02.54 and 02.55 respectively.
02.53 : Speed threshold for accel./decel.
Adjustment range : ± 01.06
Factory setting : 400.00 rpm
Format: 32 bits
See explanation in 02.52 .
02.54 : High speed acceleration ramp
Adjustment range : 0.1 to 3200.0 s
*
Factory setting : 20.0 s
Format: 16 bits
See explanation in 02.52 and 02.56 .
02.55
: High speed deceleration ramp
Adjustment range : 0.1 to 3200.0 s *
Factory setting : 20.0 s
Format: 16 bits
See explanation in 02.52 and 02.56 .
* Note:
The reference speed can be changed from 1000 to 100
min
-1
using parameter 02.56 . This makes it possible to multiply
the acceleration and deceleration times by 10.
