F3-02, F3-03, and F3-04 are used to set the running curve during which the elevator accelerates from
startup to the maximum speed. If the acceleration process is too short causing bad riding comfort,
decrease the value of F3-02 and increase the values of F3-03 and F3-04 to make the acceleration
curve smoother. If the acceleration process is too long, increase the value of F3-02 and decrease the
values of F3-03 and F3-04.
Adjust F3-05, F3-06, and F3-07 similarly to make the deceleration process appropriate.
2. Adjustment of mechanical construction
The mechanical construction affecting the riding comfort involves installation of the guide rail, guide
shoe, steel rope, and brake, balance of the car, and resonance caused by the car, guild rail and
motor. For asynchronous motor, abrasion or improper installation of the gearbox may arouse poor
riding comfort.
● Installation of the guide rail mainly involves verticality and surface atness of the guide rail,
smoothness of the guide rail connection and parallelism between two guide rails (including
guide rails on the counterweight side).
● Tightness of the guide shoes (including the one on the counterweight side) also inuences the
riding comfort. The guide shoes must not be too loose or tight.
● The drive from the motor to the car totally depends on the steel rope. Large exibility of the
steel rope with irregular resistance during the car running may cause curly oscillation of the car.
In addition, unbalanced stress of multiple steel ropes may cause the car to jitter during running.
● The riding comfort during running may be inuenced if the brake arm is installed too tightly or
released incompletely.
● If the car weight is unbalanced, it will cause uneven stress of the guide shoes that connect the
car and the guide rail. As a result, the guide shoes will rub with the guide rail during running,
affecting the riding comfort.
● For asynchronous motor, abrasion or improper installation of the gearbox may also affect the
riding comfort.
