Group 9.4 Comfort Optimisation - DC Injection operation to solve rollback during stopping
Parameter Number | Parameter Name | Units | Default | Available Settings | Access | Change During Run | Scaling | Size (Bytes) | CAN Register | CAN Sub Index | Modbus Register |
|---|---|---|---|---|---|---|---|---|---|---|---|
P9-13 | Position Lock / DC Injection Time At Stop | sec | 0.5s | 0.0 ... 10.0s | RW | Y | 1 = 0.1 s | 1 | 2391h | 0 | 913 |
P9-14 | DC Injection Current At Stop | % | 50.0% | 0.0 ... 200.0% | RW | Y | 1 = 0.1 % | 2 | 2392h | 0 | 914 |
P9-15 | Position Lock / DC Injection Speed At Stop | Hz / rpm / ft/s / m/s | 0.0Hz | 0.0 ... P8-01 | RW | Y | 1 = 0.01Hz | 2 | 2393h | 0 | 915 |
Sets the time Position Lock or DC Injection will be active for at stop.
Sets the level of current injected into the drive for the time set in P9-13.
Best value is the lowest value but with the least amount of rollback, the higher the value the more heat generated in the motor and nuisance over current trips.
Function Disabled if value entered = 0.0.
Sets the speed at which either Position Lock or DC Injection activates, depending on the motor and encoder configuration.
Best to aim for the lowest suitable value, as too high a value can cause the motor to stop to early resulting in the lift car stopping before reaching the floor.
DC Injection function is disabled if value entered = 0.0.
