This parameter sets the lowest frequency that the drive will decelerate to when in torque
limit. If the load is large enough to drive the inverter below this threshold, the drive will trip
on overcurrent. The rate of deceleration is set by
46-DECTL
. Programmable from 0.00 to
400.00 Hz. Factory set for 10.00 Hz. To disable Torque Limit, set this to a Data Code great-
er than
32-FMAX
.
◊ Value range: 0.00–400.0 Hz Default: 10.00 Hz
Selects the Acceleration and Deceleration ramps that control the motor and also enables
the coast-to-stop function.
◊ Value range: 0–7 Default: 0
Sets the length of time to accelerate from 0 Hz to
32-FMAX
. To be programmed in steps
from 0.05 seconds to 99,95 seconds and, in excess of this amount, in steps of 0.1 second.
Extremely short acceleration times may result in nuisance fault trips (see
41-RSEL
, page
39).
◊ Value range: 0.10–600.0 s Default: 3.00 s
Sets the length of time to decelerate from
32-FMAX
to 0 Hz. To be programmed in steps
from 0.05 seconds to 99,95 seconds and, in excess of this amount, in steps of 0.1 second.
Extremely short deceleration times may result in nuisance fault trips (see
41-RSEL
, page
39). Higher braking performance can be achieved with an additional external braking chop-
per (option BC6000).
◊ Value range: 0.10–600.0 s Default: 3.00 s

43-DEC1
active in Forward,
44-ACC2

45-DEC2
active in Reverse.

42-ACC1

43-DEC1
active when the output frequency is less than preset fre-
quency
37-F6

45-DEC2
active when output frequency is equal to or
greater than
37-F6
.
3 When
21-MODE
is set to 2, 3, or 6, PS3 is re-defined as the Alternate Ramp
Time (ART) selector, unless the PI Controller is utilized. When this terminal is ac-
tive,
44-ACC2
and
45-DEC2
are active. Note that PS3 cannot be used as a pre-
set speed selector when
41-RSEL
is set to 3 or when the PI Controller is enabled
and PS3 is used as an ON/OFF switch. (See Table 3.3 on page 28; also see
21-
MODE
on page 36.)

5 Same as 1, except coast-to-stop is selected when stopping.
6 Same as 2, except coast-to-stop is selected when stopping.
7 Same as 3, except coast-to-stop is selected when stopping.
