Release the brake, and after Brake Control Release Delay (DO4) ms, consider that the brake is released. If Brake Contact Monitoring Select (D11)
> 0, then when the brake contact feedback is received exit to state 5 and bypass the Brake Control Release Delay (DO4).
Exit to state 5:
•
If the drive is in a closed loop mode AND
•
When the brake release time must has elapsed, OR
•
If Brake Contact Monitoring Select (D11) > 0, the brake contact feedback via Brake Contact Monitoring Input 1 (D12) and Brake Contact
Monitoring Input 2 (D13) must both be set to On (1), indicating that the brake contact is closed i.e. the brake is released.
:
On exit to state 5
•
If Load Cell Compensation Enable (E10) =1, disable the position loop by ramping the Start Lock P Gain Speed Clamp (I21) to 0, in order to
smoothly pass the load to the speed loop.
Exit to state 6:
•
If the drive is in open loop mode and digital speed references are selected AND
•
When the brake release time has elapsed, OR
•
If Brake Contact Monitoring Select (D11) > 0, the brake contact feedback via Brake Contact Monitoring Input 1 (D12) and Brake Contact
Monitoring Input 2 (D13) must both be set to On (1), indicating that the brake contact is closed i.e. the brake is released.
Exit to state 8:
•
If analog reference mode is selected, (Control Input Mode (H11) = 0 or 1) to indicate that we are travelling based on the analog speed reference.
AND
•
When the brake release time has elapsed, OR
•
If Brake Contact Monitoring Select (D11) > 0, the brake contact feedback via Brake Contact Monitoring Input 1 (D12) and Brake Contact
Monitoring Input 2 (D13) must both be set to On (1), indicating that the brake contact is closed i.e. the brake is released.
Exit to state 12:
•
If digital speed selection is removed
•
If direction signal is removed (dual direction inputs)
•
If the Safe Torque Off (STO), Drive enable and Fast disable input (if used) are removed
•
If an autotune completes
•
If the drive trips
On exit to state 12:
•
Sample the time used to detect a brake contact fault.
•
Reset the load/direction accumulator for rescue operation
5
Accumulate Torque Producing Current (J24) and time for the rescue Load Measurement Time (O04) in ms. This is for determination of the load
direction and magnitude for rescue operation.
This state is not used in open loop mode.
Exit to state 6:
•
When Load Measurement Time (O04) has elapsed and Start Optimizer Time (G48) > 0
Exit to state 7:
•
When Load Measurement Time (O04) has elapsed and Start Optimizer Time (G48) > 0
On exit to state 7:
•
Apply the selected speed, accel start jerk, accel end jerk, decel start jerk and decel end jerk.
•
Apply the main elevator profile accel and decel rate.
•
If Start Lock Enable (I22) =1, disable the position loop by ramping the Start Lock P Gain Speed Clamp (I21) to 0, in order to smoothly pass the
load to the speed loop.
Exit to state 12:
•
If the digital speed selection is removed or the Safe Torque Off (STO), Drive enable and Fast disable input (if used) is removed or the drive trips,
or the digital direction signal is removed in dual direction input mode), transition 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
