10
Creep:
In this state the profile will run at Creep speed (
V1 Speed Reference
(
G01
)) by default, but can be any speed reference.
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 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
Positioning.
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
Apply the brake:
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
Ramp the torque down:
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.
14
Contactor control
Generate motor contactor control output.
Exit to state 0:
•
Fast Disable
(
B27
) = Off (0) AND
•
T
otal Output Current
(
J22
)
< 25 % of rated current AND
•
F10
T31 STO Input 1 State
(
F10
)= Off (0) AND
•
There is no digital speed signal present (if used) AND
•
There is no direction signal present (in dual direction signal mode) AND
•
The Fast disable input (if used) = Off (0) OR
•
The drive trips
The following error detection is made in this state after 4 s. The list is in order of priority:
1. If
Motor Contactor Monitoring Enable
(
B29
)= On (1), and it takes > 4 s for the monitoring input to be set to 0, generate a
Trip 71
(
Mot con
closd
).
2. If the
Fast Disable
(
B27
) input terminal = On (1), then generate
Trip 65
(
Fast disable err
).
3. If the F10
T31 STO Input 1 State
(
F10
) = On 1, then generate
Trip 66
(
STO Ctrl err
).
4. If the total current is > 25 % of rated, then generate
Trip 67
(
Current on stop
).
