Table 7-24 Brake control parameters
During any drive trip where brake control is being performed, the brake output will become inactive forcing the brake to be closed and preventing
further operation. If the brake control is being carried out by the Elevator controller and a drive trip occurs, the drive ok output will turn Off (0) and the
Elevator controller must apply the motor brake to prevent further operation.
Figure 7-15 Brake control - Closed loop apply
7.10.3 Stop profile, motor contactor control
Following completion of the travel and during the stop sequence the motor brake is applied, after which the symmetrical current limit is ramped down
and the output motor contactors are opened. During the opening of the output motor contactors, the drive’s output should be inactive to avoid
potential damage to both the output motor contactors and the drive as a result of arcing.
Where Motor Contactor Measured Delay Time (B32) is < 50 ms the brake control in Brake Control Apply Delay (D05) should be increased.
Table 7-25 Motor contactor control parameters
7.11 Additional control functions
There is a wide range of firmware features available on the elevator drive which are either enabled as default or could be configured on the
E300 Elevator drive. When selected, some additional features may require control inputs/outputs on the drive to be allocated. Where additional
control inputs/outputs are not available, this will require an additional SI-I/O option module to be installed. Refer to Parameter Reference Guide.
