1.13-Deceleration End Soften (S4: 0.10 – 5 .00 m/s³)
At the end of acceleration while passing to constant speed the acceleration is decreased
smoothly to prevent sharp changes in the acceleration. Consequently the acceleration is felt less
by the passenger.
1.14-Mechanical Brake on Delay (MB_ON: 0.1 – 3.0 Sn)
Delay of the mechanical brake open. For this period motor is hold at zero speed and waits for
mechanical brake to free motor. At the end of delay the elevator begins accelerating. Too short
delays causes vibration because of torque on the motor before the mechanical brake opens. Too
long delays increase the travel time.
1.15-Mechanical Brake off Delay (MB_OFF: 0.1 – 3.0 Sn)
Delay of the mechanical brake close. After the elevator reaches zero speed the motor
continue to drive at zero speed for this period. Too short delays causes the motor power cut off
before the mechanical brake blocks motor. In this situation the car may move out of control to
heavier direction. The elevator controller card must hold the contactors till the end of the this
time. If this is not done, the sparks at contactor contacts may disturb the driver.
1.16-Initializing Jerk (As: 0.01 – 4.00 m/s²)
Instead of starting directly with the S ramp, the elevator may be first accelerated to a Vs
speed with a As acceleration and to eliminate the rope tension and inertia, the actual ramp is
passed over after a delay Ts. This function is suitable for high buildings to eliminate the rope
bounce. (Not used if Vs=0)
1.17-Initializing Speed (Vs: 0 – 1.00 m/s)
Please see the parameter 1.16.
1.18-Initializing Time (Ts: 0 – 3.00 Sn)
Please see the parameter 1.16.
