P803 Parameter lock
Setting range: On/Off
• Setting "on:" The device can no longer be started. Any adjustment to the paramet-
ers is prevented. The following parameters are excluded from the inhibit:
– P803 Parameter lock
– P840 Manual reset (→2226)
– P876 PO data enable (→2230)
A parameter lock is useful, for example, after an optimized setting of the power
section "PFA-...".
• Setting "Off": Parameter adjustments are possible.
P804 Reset statistics data
Setting range: No/error memory/kWh counter/operating hours
Resets the statistical data, error memory, kilowatt-hour meter, and operating hours
counter stored in EEPROM.
This data is not reset when selecting the "Standard" standard of the parameter P802
Factory setting (→2222).
P82. Braking operation
P820/P821 4-quadrant - operation1/2
Setting range: ON/OFF
The parameter is only effective in operating modes without encoder feedback (VFC
and V/f). 4-quadrant operation is assumed in all other operating modes.
• If a braking resistor is connected to the device, the following 4-quadrant operating
modes are possible:
– Left/right
– Motor/regenerative
• Parameter must be set to "OFF" if there is no braking resistor connected to device,
which means regenerative operation is not possible.
In these operating modes, the device attempts to extend the deceleration ramp so
the generated power is not too great and the DC link voltage remains below the
switch-off threshold.
Despite the fact that the deceleration ramps are automatically extended by device,
it is possible that the regenerated power during braking may be too great, leading
to device switching itself off and issuing error message "F07 "(DC link over-
voltage). In this case you have to extend the deceleration ramps manually.
