Alternate Acceleration Ramp. Same adjustment range as of
42-ACC1
(see
41-RSEL
, page
39).
◊ Value range: 0.10–600.0 s Default: 1.00 s
Alternate Deceleration Ramp. Same adjustment range as of
43-DEC1
(see
41-RSEL
, page
39).
◊ Value range: 0.10–600.0 s Default: 1.00 s
This parameter sets the deceleration rate when the drive is operating in torque limit mode.
Programmable from 0.10 to 30.00 seconds. It also serves as the acceleration rate when the
drive is in torque limit due to a regenerative condition (see also
39-FTL
, page 39.
◊ Value range: 0.10–30.00 s Default: 1.00 s
This is the time in seconds that DC current will be applied to the motor windings with the
following conditions:
Data Code = 0.00 s:
DC braking disabled in all modes.
Data Code = 0.05–4.95 s (Timed DC braking):
1. In terminal strip Stop/Start, when both FWD and REV terminals are active.
2. In FWD or REV run mode and the speed reference is reduced to less than 0.1 Hz.
3. A Stop command is given and the output frequency decelerates to less than 0.1 Hz.
Data Code = 5.00 s (Continuous DC braking):
1. In terminal strip Start/Stop, as long as both FWD and REV terminals are held active.
2. In FWD or REV run mode and the speed reference is reduced to less than 0.1 Hz.
3. There is no DC braking after a normal decelerate to stop.
◊ Value range: 0.00–5.00 s Default: 0.20 s
This controls the amount of DC voltage applied to the motor windings by
47-DCBRK
. Pro-
grammable from 0.00 to 15.00% of the setting of
52-BOOST
.
If DC Braking is used as a holding brake, excessive motor heating may result.
◊ Value range: 0.00–15.00% Default: 2/3 of
52-BOOST
(%)
Three V/Hz characteristics (constant torque, pump and fan curves) and two starting torque
boost features may be selected.
44-ACC2 – Acceleration Time 2 [s] 2P
45-DEC2 – Deceleration Time 2 [s] 2P
46-DECTL – Deceleration Time in Torque Limit [s] 2P
47-DCBRK – DC Brake Time [s] 2P
48-DCVLT – DC Brake Voltage [%] 2P

DESCRIPTION
0 Linear V/Hz, with Auto-Boost, used with constant torque applications. With Auto-
Boost, the optimum boost will be selected depending on load and motor condi-
tions, parameter
52-BOOST
sets the maximum boost applied.
