Door command

The door command board can command either one or two doors with alternative, selective or passage through opening. Output and inputs are available on the jst connectors on the TOC board and on APPO board (in the controller).

The doors can be automatic, semi-automatic or manual:

DOOR A

  • ROA output (relay open door A) open collector max 24V 100mA
  • RFA output (relay closing door A) open collector max 24V 100mA
  • Input BRA (A oor opening button relay) closed to GND (NA) I = 5mA
  • Input CEA (A door photocell) closed to GND (NA) I = 5mA
  • Input FOA (A door opening limit) closed to GND (NA) I = 5mA
  • Input FFA (A door closing limit) closed to GND (NA) I = 5mA

DOOR B

  • ROB output (relay opening door B) open collector max 24V 100mA
  • RFB output (relay closure door B) open collector max 24V 100mA
  • Input BRB (B door opening button relay) closing to GND (NA) I = 5mA
  • Input CEB (B door photocell) closing to GND (NA) I = 5mA
  • Input FOB (B door opening limit) closing to GND (NA) I = 5mA
  • Input FFB (B door closing limit) closing to GND (NA) I = 5mA

Weight load control

When COM input is active, floor reservation calls are neither recorded nor managed.

When SUR input is active the elevator car does not start and the acoustic signal in the elevator car is activated. The SUR signal is ignored while driving.

Elevator car Position / Speed Control with Motor Encoder

This control system can only be used on systems with inverter VVVF with a Gearless Motor.

Location, stop and deceleration are controlled by counting the pulses coming from the encoder of the motor. The counting of the pulses is suitably corrected (reset) by the reset signals at the top and bottom (AGB / AGH) and from the signal of door zone (ISO1).

The same J16 input connector is used to connect, with the appropriate cable, the encoder interface card, which is inside the FUJI inverter.

Parameter ”Count System” should be set as “engine encoder”. In menu choose 2048 number of pulses. Subsequently the dimensional parameters of the motor pulley and the type of pulling system should be inserted. Next the system asks to set the shaft length in order to set the correct sensitivity. Only after these steps are completed, Will it be possible to run the automatic floor levelling procedure.

Rollback control and ride comfort

When the Playboard controller is applied to installations equipped with closed loop gearless machines, comfort and precision can be optimized thus avoiding undesired effects such as rollback (typical of lifts with unbalanced load).

The following parameters can be adjusted to achieve optimal setting for your installation. It is suggested to follow the procedure from start to end in the proposed sequence.

Starting phase adjustments
Adjust the following Parameters to compensate for other undesired effects.

ParameterDescriptionDefaultSuggested Adjustments
GearlessGeared
H64Zero speed control time 0,80,8Set value between 0,7 and 0,8 then increase to soften start phase ramp
Important: In “Positioning” Menu :
Delay DIR-BRK <= 0,2 s
Delay BRK-S > H64
L68RBC Proportional Gain (P constant)
(specifies the P constant of the Automatic Speed Regulator to be used during RBC calculation time)
1,810Motor overshoots: increase value by 0,25

Vibrations: decrease value by 0,25
L69RBC Integral Time (I constant)
(specifies the I constant of the Automatic Speed Regulator to be used during RBC calculation time)
0,003 s0,010 sMotor overshoots: decrease value by 0,001

Vibrations: increase value by 0,001
L73Unbalanced load compensation
(specifies the I constant of the Automatic Position Regulator to be used during RBC calculation time)
0,50Motor overshoots: increase value by 0,50

Vibrations: decrease value by 0,50
L82ON delay time
(specifies the delay time during which the inverter main circuit is kept activated)
0,2 s0,2 sLarger Brakes: decrease value by 0,1

Smaller brakes: increase value by 0,1


Notes: L65 specifies whether to enable or disable the unbalanced load compensation (Rollback control). By default, it is set to 1 (Rollback control active). Speed is kept at zero when brakes are released to avoid rollback effect.
High speed phase adjustments
High speed “P” gains and “I” time constants are used by the Auto Speed Regulator (ASR) of the inverter during high speed lift travel. These constants can be adjusted as follows:

ParameterDescriptionDefaultSuggested Adjustments
GearlessGeared
L24“S” Curve setting 625$25%Speed fluctuations: increase value by 5
L36“P” Gain constant at high speed210Speed fluctuations increase value by 0,25
Vibrations: decrease value by 0,25
L37 “I” Time I constant at high speed0,100 s0,100 sSpeed fluctuations decrease 0,01
Vibrations: increase value by 0,01

Notes:
Increasing the P constant makes response from machinery faster but may cause overshooting or hunting in motor. Furthermore, due to resonance of machinery or overamplified noise, machinery or motor may produce vibration noise.
On the contrary, decreasing the P constant excessively delays response and may cause speed fluctuation in a long cycle, taking time to stabilize the speed.
“I” times values (L37 and L39) normally do not need to be changed, unless “P” gains are not enough to achieve optimal comfort. Setting a small “I” Time constant shortens the integration interval, providing a faster response. On the contrary, setting a large “I” Time constant lengthens it, having less effect on the ASR. This may help in case of resonance of machinery generating abnormal mechanical noise from the motor or gears
.
Stopping phase adjustments
Use the constants of the gains “P” and the times “I”, at low speed, to make the final adjustment for the stop phase:

ParameterDescriptionDefaultSuggested Adjustments
GearlessGeared
E16Deceleration time # 9
(Last deceleration ramp)
1,80 s1,80 sIncrease value by 0,5 to soften last ramp (max suggested value: 3 sec)
H67Stop Hold Time1,5 s1,5 sCar unable to stay at floor: increase 0,25
Important: In “Positioning” Menu :
Delay BRK-DIR <= 2,0 s
Stopping Boost = 1% or 2%
L38“P” Gain constant at low speed210Car unable to stay at floor: increase 0,25
Vibrations: decrease value by 0,25
L39I” Time I constant at low speed0,100 s0,100 sCar unable to stay at floor: decrease value by 0,01
Vibrations: increase value by 0,01
L83Brake Control (OFF delay time)
(specifies the delay time between stop speed and deactivation of the brake signal)
0,3 s0,1 sLarger Brakes: decrease value by 0,1
Smaller brakes: increase value by 0,1

Notes: In order to let the inverter perform the stopping phase correctly, make sure that operating contactors open at least 2 sec after brake contactor. If operating contactors open in advance, a shock on the machine may be heard.
VVVF controllers with non-encoder based positioning systems
If a digital position system is used in the installation (i.e.: digital signal from magnetic detectors), some additional parameters must be used:

ParameterDescriptionDefaultSuggested Adjustments
F24Starting speed holding time0,7Set value between 0,7 and 0,8
H64Zero speed control time0Set value to 0
E12Acceleration at high speed 2Speed fluctuations: increase value by 0,25
E13Acceleration at low speed2Motor stops: increase value by 0,25
C07Creep Speed (5-10% of high speed)Motor stops: increase value by 0,1
Vibrations: increase/decrease value by 0,1
C11High SpeedSee Nominal Value on the motor plateIf the elevator car is unable to keep floor level, make sure the low speed phase is performed correctly by reducing high speed C11 to half of its value to check that low speed is kept for few seconds, then slowly increase C11
