Adjust for the feeling of comfortablef)
Adjusting the F3 group parameters to make lift run with comfortable feeling. If the lift is
wobbling, amend relevant parameters according to curve chart 6-2. Details are described in
section 6.4.
Notice: Lift comfortable feeling is affected by many factors. The miss-adjustment of machine
part and the inappropriate section of parameters will bring on the bad c
omfortable feeling.
The effect on the comfortable feeling by the machine part generally can be caused in the
following conditions:
Detect hoist machine’s worm-wheel and worm-shaft.
Lift guide’s verticality doesn’t only affect horizontal tremor in running, but also affect
the vertical shaking in running.
Lift’s running quality is related to the car guide shoe. If want to achieve better PMT
testin
g curve, you should do car static balance and car dynamic balance. Let car guide
shoe bear the least resistance, and achieve lift best quality of running.
The counterweight guide shoe’s miss-verticality and bearing resistance affect lift’s
comfortable feeling too.
Brake affect lift’s starting and stopping dramatically.
It can affect lift comfortable feeling that the joint between the motor and ho
ist machine
loose or fray.
The unbalanced pull of lift steel rope is the epicenter of the tremor.
The shock absorption tray under car top, car platform and machine platform all affect lift
running quality.
Parameter selection affects lift comfortable feeling. Parameter unsuitable setting brings shake
in vertical direction:
F1-01~F1-11of motor parameters are main parameters of controller to contr
ol motor. If
motor mode selection, parameter setting or auto-tuning isn’t right, it can bring on motor
shaking or noise, and affects comfortable feeling.
F1-12 set the pulse number of each rotation of the encoder. If the setting is different from
the actual pulse number, it can cause that the controller can’t recognize the current
speed and position, thereby bring on the motor shaking or noise.
F2-00~F2-07 are the using parameters when adjusting the controller PID is adjusting. It
decides that the responding speed of the practically output voltage waveform of controller
to the expected output value. It causes continuous undulation that the proportion
adjusting is too large or the integral adjusting is too little.
F3-18:Output time of starting zero speed, F3-19: Time-lag of curve running
, F3-20: Time-
lag of end running. They relate to the condition that whether it’s zero speed or not when
the lift is starting or stopping and brake is open. If lift speed isn’t 0, it can bring the
pause feeling when starting and stopping.
F3-03:Inexion speedup time 1, F3-04: Inexion speedup time 2.They is the speedup
time of the S curve running to starting segment and ending segment. If the sp
eedup time
is too shot, it can bring shake at relevant moment and it can be appropriately increased.
F3-06:Inexion speed down time 1, F3-07: Inexion speed down time 2. They are the
speed down time of the S curve running to starting segment and ending segment. If
the speed down time is too shot, it can bring shake at relevant moment and it can be
appropriately increased.
