The function cannot be actuated via the keypad!
Application:
Fast stop
is actuated in emergencies and hazardous situations, in order to stop the drive in the
shortest possible time. This method of stopping has the advantage over disconnection in that with a four quad
-
rant drive (TPD32-EV... 4B) energy can be recovered in the AC input and the motor can be brought to a halt in
a shorter time than when it coasts down.
The
Fast stop
command is always required for operation of the converter. A removal of the command when the
drive is running initiates braking with the ramp specified by the parameters
Qstp delta speed
and
Qstp delta time
.
When the drive is brought to a halt, it is still enabled and has torque. The
Start
command or
Enable drive
com
-
mand must be removed for it to be disconnected.
The drive behavior after the Fast stop command has been given depends on the type of operating mode selected:
- Operation via the terminal strip (
Main commands
= Terminals):
The drive executes braking until there is no voltage on terminal 14. When voltage is restored, the drive
automatically accelerates to the required reference value (precondition: the other enable commands are still
active).
- Operation via serial line with commands given via terminals too (
Main commands
= Digital):
The drive executes braking until it has come to a halt. When voltage is restored on terminal 14, there is no
automatic start. This requires the entry of the Start command.
- If the
Fast stop
command is actuated via the serial interface while there is a voltage present on terminal 14,
the fast stop is executed until the drive is at a halt. The
Start
command must be entered for the drive to be
restarted.
