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 increases 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.

1.20-Re-Levelling Speed (VL: 0.01 – 0.20 m/s)

Re-levelling speed is active when V1 and V2 inputs are ON at the same time. V0 is don't care

(X). V3 shall be OFF. Normally it is suggested to use re-levelling in closed loop operations with

VL: 0.05 m/s speed. For open loop applications higher values (> 0.1 m/s) shall be set.
