Exit to state 10:
•
If Creep to floor is selected (Elevator control mode = Off (0)) and when Creep speed is reached.
For Creep to floor exit to state 10, for Direct to floor exit to state 12.
On exit to state 10:
•
Apply the final positioning jerk
Exit to state 12:
•
If Direct to Floor is selected (Elevator control mode = On (1)) when the positioning profile has completed i.e. zero speed.
•
If the Safe Torque Off (STO), Drive enable and Fast disable input (if used) are removed or the drive trips, go to state 12 and apply the brake.
•
On exit to state 12:
•
Sample the time used to detect a brake contact fault.
•
Reset the load / direction accumulator for rescue operation.
10
In this state the profile will run at Creep speed (V1 Speed Reference (G01)) by default, but can be any speed reference.
This state is not used if (Elevator control mode = On (1)) i.e. Direct to floor mode is selected.
Exit to state 11:
•
When Creep speed is deselected OR
•
When the floor sensor correction input is given
On exit to state 11:
•
Apply Creep Stop Deceleration Rate (G17) and Creep Stop Jerk (G18)
Exit to state 12:
•
If Direct to Floor is selected (Elevator control mode = On (1)) when the positioning profile has completed i.e. zero speed.
•
If the Safe Torque Off (STO), Drive enable and Fast disable input (if used) are removed or the drive trips, go to state 12 to apply the brake.
On exit to state 12:
•
Sample the time used to detect a brake contact fault.
•
Reset the load / direction accumulator for rescue operation
11
Wait for zero speed if a normal creep stop is used i.e. no floor sensor correction. If floor sensor correction is used use the creep stop profile distance
as the distance to floor and position correct to a stop.
Exit to state 12:
•
When zero speed is reached i.e. motion profile is complete.
•
If the Safe Torque Off (STO), Drive enable and Fast disable input (if used) are removed or the drive trips, go to state 12 to apply the brake.
On exit to state 12:
•
Sample the time used to detect a brake contact fault.
•
Reset the load / direction accumulator for rescue operation
12
Set Brake Control Output (D03) = Off (0) and wait Motor Torque Ramp Time (D02) ms for the brake to be applied. For systems where the brake
control is implemented in the elevator controller Brake Control Output (D03) may be used to indicate when to apply / release the brake.
Exit to state 13:
•
If Brake Contact Monitoring Select (D11) > 0, and this takes longer than Brake Contact Monitoring Time (D14), generate a Trip 73 (Brk con 1
closd) / Trip 75 (Brk con 2 closd).
•
If the Safe Torque Off (STO), Drive enable and Fast disable input (if used) are removed or the drive trips
13
Sample the motor encoder position, and then ramp the Torque producing current to 0% in the time specified by Motor Torque Ramp Time (D02) in
ms. When the ramp has completed move to the next state.
Don't sample the position if the previous state was < 6
Exit to state 14:
•
When the torque producing current limit has been ramped to 0 using the Motor torque ramp time via Symmetrical Current Limit (B16) and Motor
Torque Ramp Time (D02)
•
If the Safe Torque Off (STO), Drive enable and Fast disable input (if used) are removed or the drive trips
On exit to state 14:
•
Sample the time on exit for use to detect a feedback issue with the motor contactors, or a Safe Torque Off (STO), Drive enable and Fast disable
input (if used) issue.
•
Disable the drive via and remove the run signal.
