176 Parameters
21.21
DC hold frequency
Defines the DC hold frequency, which is used instead of
parameter
21.09
DC hold speed
when the operating mode
in use is
Scalar frequency mode
. See parameters
19.01
Actual operation mode
,
21.08
DC current control
, and
section
DC hold
on page
77
.
5.00 Hz
0.00…1000.00 Hz
DC hold frequency.
1 = 1 Hz
21.22
Start delay
Defines the start delay. After the conditions for start have
been fulfilled, the drive waits until the delay has elapsed
and then starts the motor. During the delay, warning
AFE9
Start delay
is shown.
Start delay can be used with all start modes.
0.00 s
0.00…60.00 s
Start delay
1 = 1 s
21.23
Smooth start
Enables smooth start function. Smooth start function
restricts the motor current below the limit defined by
parameter
21.24
Smooth start current
when the motor
speed is below
21.25
Smooth start speed
.
Disabled
Disabled
Smooth start disabled
0
Enabled always
Smooth start function is always active when speed is
below limit.
1
Start only
Smooth start function is only active after start while the
speed is below limit.
2
21.24
Smooth start current
Current applied to motor when the smooth start is active.
50.0%
10.0... 100.0%
1=1%
21.25
Smooth start speed
Set the smooth start speed when the current is applied.
10.0%
2.0... 100.0%
1=1%
21.26
Torque boost current
Defines the maximum supplied current to motor during
‘Torque boost’ –starting mode. Parameter value is in
percent of the motor nominal current. Nominal value of the
parameter is 100.0%. ‘Torque boost’ –starting mode can
be used only when motor control mode is ‘Scalar’. Torque
boost is only applied at start, ending when output
frequency exceeds 40% of nominal frequency or when
output frequency is equal to reference.
100.0%
15.0... 300.0%
0.01 = 1%
21.30
Speed compensated
stop mode
Selects the method used to stop the drive. See also
section
Speed compensated stop
on page
80
.
Speed compensated stop is active only if
• the operation mode is not torque, and
• parameter
21.03
Stop mode
is
Ramp
, or
• parameter
20.11
Run enable stop mode
is
Ramp
(in
case Run enable is missing).
Off
Off
Stop according parameter
21.03
Stop mode
, no speed
compensated stop.
0
Speed comp FWD
If the direction of rotation is forward, speed compensation
is used for constant distance braking. Speed difference
(between used speed and maximum speed) is
compensated by running the drive with current speed
before the motor is stopped along a ramp.
If the direction of rotation is reverse, the drive is stopped
along a ramp.
1
