F203 2nd Deceleration ramp VC 0,01...3600 s 30 s
Setting of required deceleration time. The time is in reference with the range from 0 Hz to maximum
frequency (parameter A204).
A220 2nd Internal pre-set speed VC 0,00...400,0 Hz 0,00 Hz
Entry of frequency reference value, if function A001 is set to position 02. Allows the entry of a
minimum frequency to which the inverter runs up without selecting a digital input “CF1...CF4” as
soon as a Start-command is issued.
If the PID controller is active, the adjusting range changes into 0 to 100 %.
A241 2nd Torque boost method selection VIC 00 or 01 00
Setting Function
00 manual boost
01 automatic boost
A242 2nd Manual torque boost setting VC 0,0...20,0 % 1,0 %
A243 2nd Manual torque boost frequency point VC 0,0...50,0 % 5,0 %
For applications which require higher starting torque, the standard starting torque can be increased
by up to 50 %. Use parameter A241 to select between automatic and manual boost. Parameter
A242 defines the value by which the torque has to be boosted. The range in which this boost takes
effect is defined by parameter A243.
(more information see parameters A042 and A043)
A244 2nd V/f characteristic setting VIC 00 to 02 00
Parameter to set one of the possible V/f characteristics.
Setting Function
00 constant torque
01 reduced torque (Economy mode)
02 free adjustable V/f characteristic (b100...b113)
A261
2nd Frequency upper limit VIC 0,00...400,0 Hz 0,00 Hz
A262
2nd Frequency lower limit VIC 0,00...400,0 Hz 0,00 Hz
Defining the frequency range within a range from 0 to parameter A204 (max. 400 Hz). If the values
are set to 0,00 Hz, their function is cancelled (more details see parameters A061 and A062).
