7.9.5 Connection diagram for emergency maneuver (for synchronous motor only)
Emergency maneuver with operator present. This function allows the car to move when there is a power failure in order
to bring it to the closest floor by gravity.
•
This maneuver can be performed only when the drive is in emergency mode, which the control card indicates with
the “Emergency Mode” digital input.
•
Only for gearless applications (with synchronous motors).
•
There must be a digital input ("Digital input Y" in the figure below) connected to a
Brake release src
button on the
control panel that will enable car movement. The input is configurable by the
Brake release src
(PAR 11820).
•
When the button is pushed the inverter opens the brake contactor via the
Brake Contactor Relay
output.
•
The operator then pushes the button to move the car.
•
With parameter 11822
Em max speed
(Emergency manual max. speed) you can set maximum car (or motor)
speed during this maneuver. The speed can be expressed in m/s (for the car) or in rpm (for the motor).
•
If the car reaches the maximum allowed speed, the drive locks the brake for a time T configurable by parameter
11824
Brake lock time
, disabling use of the button (which will not release the brake even if pushed).
•
As soon as emergency manual maneuver is resumed, the display (both optional and built-in) automatically shows
the current car speed (or motor speed if set in rpm) and direction (Fwd or rev).
•
This maneuver must be disabled in case of inspection.
The car will move (Brake Contactor = Open) only in the following conditions:
•
Emergency Mode: ON (Contactor Closed)
•
Brake release src
: ON (Contactor Closed)
•
Emergency Manual V: < Em max speed
•
Contactor Lock Time = 0
