12. Lift control program Drive control logic
Basic start/stop logic with two digital inputs
Typically two start commands: 1) UP and 2) DOWN
Alternatively: 1) START and 2) DIRECTION (UP/DOWN)
Start/stop interlocking
Provides an interlocking to stop the drive or disable the start without generating any fault or warning
End limit logic
Generate emergency stop (class 1 - controlled) command when the final limit switch is activated in the respective motor direction
Inspection mode operation
Dedicated mode used for maintenance operation
Inspection speed reference and acc/dec times
© ABB Group
April 12, 2017 | Slide 12

13. Lift control program Mechanical brake control
Application software inside the drive control board (JCON) is controlling the mechanical brake via relay output
Lift control includes additional functionality for basic brake control
Torque proving – electrical check
Brake slip detection - mechanical check
Fault diagnostics
“Gong sound remover” by limiting stopping torque in PM motors due to rapid change in di/dt
Brake open torque selection
Pre-defined value
External AI signal, e.g. weight
Can be disabled, if the lift control system takes care of brake control

April 12, 2017 | Slide 13

14. Lift control program Rescue operation
Lift car has to run to the nearest floor in case of power failure situation
Precondition: 1-phase UPS-supply or DC-battery available
When the start command is given by the lift controller, the drive checks the load in the downward and upward directions and then based on the lighter load, automatically starts to corresponding direction
Alternatively the lift controller decides the starting direction
Separate speed reference and acceleration/deceleration times
Jerk times (shape times) disabled

April 12, 2017 | Slide 14

15. Lift control program Automatic fault reset
Typically needed in applications, where maintenance staff is not directly available for performing fault reset
Resets automatically pre-defined drive faults
Easy configuration by the user
Both application and firmware faults
Number of trials and trial time (period) can be configured
Delay time for starting auto reset after fault is adjustable

16. Lift control program Speed profile
Main task to attain high riding comfort and leveling accuracy
Guarantee the smooth movement of the lift car
High control performance with DTC
7 jerk settings can be selected for different lift operation sequences
4 different acceleration/deceleration times
© ABB Group
April 12, 2017 | Slide 16

17. Lift control program Speed reference selection
Easy configuration with three selection signals (DIs)
Totally 8 different speeds
Releveling speed
Leveling speed
Nominal speed
Inspection speed
Medium speed
Speed 1, 2 and 3
Off-delay feature for holding the speed reference
Adjustable delay time and speed limit
Separate speed selection commands for evacuation and inspection modes

April 12, 2017 | Slide 17

18. Lift control program Smart slowdown for optimizing the leveling
Needed, if the normal running speed is not reached between the floors
Typical case is a short floor distance
Reduces the leveling run and thereby optimizes the travel time of the lift
Lift shifts from the nominal speed to the leveling speed only when the leveling distance is reached
Two modes
Estimated
Integral of the estimated speed
Encoder
Actual position

April 12, 2017 | Slide 18

19. Lift control program Supervision and protection functions
Speed match supervision
Monitors the motor actual speed with respect to the speed reference and checks that the actual speed follows the speed reference with a configurable speed deviation limits
Inverter overload supervision
Monitors the inverter current, torque and power and checks that the drive is operating within the inverter limits
Motor stall protection
Monitors the motor torque at lower speeds and checks that the motor torque is within the configurable limits
Action and diagnostics
Drive trips and an alarm is given

20. Lift control program Torque compensation
Method to calculate needed torque due to load and losses beforehand and hereby to help speed regulator for better control accuracy and performance
Functionality
Static friction compensation
Dynamic friction compensation
Inertia compensation, i.e. acceleration compensation
Final torque compensation ∑

Lifting application solution for passenger lift without counterweight
Very good control performance
Starting torque accuracy at zero speed
Weighting function without load cell
Requirement for open loop solution
To get rid of encoders
ABB was only supplier able to do it successfully
Customer’s opinion of ABB’s solution “Lift control with ACSM1 in open loop was more accurate than competitors’ solution with closed loop”
