8) Parameter group 100: Basic parameters
F113
Internal speed reference (Hz)
Range: F112 - F111
Default setting: 50.00 Hz
Virtual internal speed reference, it is selectable in the same way, as any external speed reference
(see F203, F204).
If
selected, after the START command, the inverter will reach this speed value.
F114
Acceleration ramp 1 (sec.)
F115
Deceleration ramp 1 (sec.)
Default setting: 0.2 - 3.7KW, 5.0 sec.
5.5 - 30KW, 30.0 sec.
> 37KW, 60.0 sec.
F116
Acceleration ramp 2 (sec.)
F117
Deceleration ramp 2 (sec.)
Range: 0.1 – 3000 sec.
Default setting: 0.2 - 3.7KW, 5.0 sec.
5.5 - 30KW, 30.0 sec.
> 37KW, 60.0 sec.
Acceleration ramp: Time to reach 50 Hz, or F-max (it depends on
F119
)
Deceleration ramp: Time, to decelerate to 0 Hz, referred to 50 Hz, or F-max (depending on
F119
)
The second ramp set is selectable via programmable digital input (OP1..OP8) -
(F316~F323).
F119
Reference for Accel./Decel. ramp
time
Selection: 0: 0 ... 50.00Hz
1: 0 ... F-max
Default setting: 0
If
F119=0
, ramp time is the duration from 0 Hz to 50 Hz, If
F119=1
it is from 0 Hz to F-max.
F118
Knee frequency (Hz)
Range: 15.00 - 650.0
Default setting: 50.00Hz
Frequency, corrisponding to the maximum inverter output voltage, the U/F characteristics reaches the horizontal range
Below the knee-frequency, the drive system operates in constant torque, above it works with constant power
ATTENTION!! Wrong setting of the Knee-Frequency may destroy the motor
F120
Dead time during reversion (sec.)
Range: 0.0 – 3000 sec.
Default setting: 0.00 sec.
If activated (>0), the inverter will stop at 0Hz during the reversing cycle, indicated as
0
.
on the display. (these parameter has no
effect, if automatic frequency cycling is chosen).
This function may be useful, to avoid torque/current peaks during reversion
F122
Reverse operation disable
Selection: 0: reversion enabled
1: reversion disabled
Default setting: 0
If
F122=1
the inverter can operate in one rotating direction only, regardless of different other settings or control signals. A reversing
command will result in inverter STOP
If inverter rotation is set to "reverse" by parameter (
F202=1
), and
F122
is set to "reversing disable", the inverter will not start
If "Catch on the fly" function is active, it will catch the motor, beginning with 0.0 Hz
F123
Reversing enable with combined
speed control
Selection: 0: disable
1: enable
Default setting: 0
If in case of combined speed control, the speed result becomes negative (reverse rotation), this function may be used to
enable/disable the reverse rotation of the motor. If disabled, in case of negative speed, the inverter output 0,0 Hz (Parameter
F122=1
overwrites this setting)
