Operation and Software
106 BA8230
AWE time
This parameter is used to set the maximum interrupt time caused by mains failure
after which the automatic restart facility (AWE) can switch the drive on again. If the
mains supply returns during the AWE time setting, a short automatic self-test lasting
approx. 0.5 s is executed before an automatic restart if the On/Stop signal is still
present.
If the mains supply only returns after the AWE restart time has elapsed, the 8230
frequency inverter must be switched on again. A high/low flank for the ON signal is
then required to start the drive. The signal ON status is only checked once the self-
test is complete. It is only then possible to generate an ON flank.
If “Kinetic back-up” is active, the pulses are not disabled directly on mains failure, as
kinetic energy to support operation of the control electronics and for controlling the
drive is taken from the drive until it is close to a standstill.
If “Capture” is active, after restarting drives without an incremental encoder a search
is first executed and, when the motor synchronous frequency is detected,
magnetisation is applied accordingly and the system is regulated to the actual speed
demand.
If the 8230 frequency inverter control unit was selected as the control source for the
On/Stop signal on mains supply failure or return, no automatic restart will take place.
Adjustment range: 0 ... 15 s
As supplied: 0 s
Note:
The controller is not reconnected automatically, if the operating unit of the 8230
frequency inverter was activated as the signal source for the ON/STOP signal during
mains failure or mains recovery.
MANUAL control
This parameter selects the source of the control signals for “MANUAL” operation.
Select list: - Terminal strip
- Control unit
- Field bus 1
- Field bus 2
- RS422
As supplied: Control unit
Select control unit:
The control unit signals START, STOP, + (HIGHER), - (LOWER) and
ACKNOWLEDGE are effective. All other control signals continue to take effect
through the terminal strip. In particular this means: If the drive is to be controlled in the
“MANUAL” mode via the control unit, the following terminals on the terminal strip are
to be connected to +24 V (terminal :1 or terminal :25):
Terminal :7 (STOP)
Terminal :8 (Fast STOP)
Terminal :10 (Inverter disable)
Terminal :12 (External error)
Terminal :9 or :11 (Direction)
