Parameters in the Long parameter mode
No.
Name/Value
Description
Default
22
ACCEL/DECEL
Acceleration and deceleration times
2202
ACCELERATION RAMP TIME
Acceleration ramp time from 0 to base speed (Parameter
9907
MOTOR
RATED FREQUENCY) in seconds.
30.0 s
0.00…600.0 s
Time
2203
DECELERATION RAMP
TIME
Deceleration ramp time from base frequency (Parameter
9907
MOTOR
RATED FREQUENCY) to standstill in seconds.
When set to zero, fastest
possible ramp time without trip is activated.
When set to 0.00, the value of 2206 is used.
30.0 s
0.00…600.0 s
Time
2206
2nd DECELERATION
RAMP TIME (FAST STOP)
Parameter programs an alternative deceleration ramp down time for the
DRIVE, which can be selected by digital inputs (dependent on the setting
of Parameter 9902 DIGITAL INPUTS FUNCTION SELECT or selected
automatically in the case of a mains power loss if parameter 2102 STOP
MODE = 2.
0.00
0.00…600 s
When set to 0.00, the drive will coast to stop.
25
CRITICAL SPEEDS
Speed bands with which the drive is not allowed to operate.
The Skip Frequency function is used to avoid the DRIVE operating at
a certain output frequency, for example at a frequency which causes
mechanical resonance in a particular machine.
2500
SKIP FREQUENCY
HYSTERESIS BAND
The drive output frequency will ramp through the defined band at the rates
set in parameter
2202
and
2203
and will not hold any output frequency
within the defined band. If the frequency reference applied to the drive is
within the band, the drive output frequency will remain at the upper or lower
limit of the band.
0.0 Hz/RPM
0.0…
2008
2501
SKIP FREQUENCY
Defines the center point of the skip frequency band, and is used in
conjunction with parameter 2500 SKIP FREQUENCY HYSTERESIS BAND
0.0…2008
26
MOTOR CONTROL
Motor control variables
2601
ENERGY OPTIMIZER
Only active when enhanced V/F motor control mode is selected (parameter
9903 MOTOR CONTROL MODE = 2)
1
0 : DISABLED
1 : ENABLED
The Energy Optimizer attempts to reduce the overall energy consumed by
the drive and motor when operating at constant speeds and light loads.
The output voltage applied to the motor is reduced. The Energy Optimizer
is intended for applications where the drive may operate for some periods
of time with constant speed and light motor load, whether constant or
variable torque.
2603
V/F MODE VOLTAGE BOOST
Voltage boost is used to increase the applied motor voltage at low output
frequencies, in order to improve low speed and starting torque. Excessive
voltage boost levels may result in increased motor current and temperature,
and force ventilation of the motor may be required.
A suitable setting can usually be found by operating the motor under low
load or no load conditions at approximately 5Hz, and adjusting parameter
2603
until the motor current is no more than 80% of the rated full load
current.
3.0 %
0.0…25.0 %
2606
EFFECTIVE SWITCHING
FREQUENCY
Sets maximum effective switching frequency of the drive. If “
rEd
” is
displayed, the switching frequency has been reduced to the level in
Parameter 0417 INTERNAL EFFECTIVE SWITCHING FREQUENCY due to
excessive drive heat sink temperature.
Refer to parameter 0417 INTERNAL EFFECTIVE SWITCHING FREQUENCY
for further information regarding operation at higher switching frequency.
Drive Rating
Dependent
4…32 kHz
