Parameters
P82x Brake operation
P820 / P821 4-
quadrant opera-
tion 1 / 2
Setting range: ON / OFF
This setting is only taken into account in operating modes without encoder feedback
(VFC); 4-quadrant operation is used in all other operating modes. P820 / P821 enables
4-quadrant operation to be switched on and off for parameter sets 1 / 2. 4-quadrant
operation is possible if a braking resistor or a regenerative power supply unit is connect-
ed to MOVIDRIVE
®
(CCW / CW; motor / regenerative). P820 / P821 must be set to
"OFF" if there is neither a braking resistor nor a regenerative power supply unit connect-
ed to MOVIDRIVE
®
, which means regenerative operation is not possible. In these oper-
ating modes, MOVIDRIVE
®
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
MOVIDRIVE
®
, it is possible that the generated power during braking may be too great,
leading to MOVIDRIVE
®
B switching itself off and issuing fault message F07 (DC link
overvoltage). In this case you have to extend the deceleration ramps manually.
P83x Fault
responses
The following responses can be programmed:
P830 Response
EXT. ERROR
Default setting: EMERG. STOP/FAULT
The error is only triggered in the ENABLED inverter status. P830 programs the error
response that is triggered by an input terminal programmed to "/EXT. ERROR."
P831 FIELDBUS
TIMEOUT
response
Default setting: RAPID STOP/WARNG
The error is only triggered in the ENABLED inverter status. P831 programs the error re-
sponse which is triggered by the fieldbus timeout monitoring. The response time of the
monitoring function can be set with P819 Fieldbus timeout delay (see "Fieldbus Unit Pro-
file" for more details).

Response
Description
NO
RESPONSE
No error is displayed and no error response is undertaken. The error which is signaled is
completely ignored.
DISPLAY
ERROR
The error is displayed (in 7-segment display and SHELL), the fault output is set (if pro-
grammed). The unit has no other fault responses. The error can be reset (terminal, RS485,
fieldbus, auto-reset).
IMM.
STOP/FAULT
The inverter performs an immediate switch-off and an error is signaled. The output stage is
inhibited and the brake is applied. The ready signal is revoked and the error output is set, if
programmed. A restart is only possible after an error reset has been performed during
which the inverter is reinitialized.
EMERG.STOP/
FAULT
The drive is braked with the emergency ramp t14/t24. Once the stop speed is reached, the
output stage is inhibited and the brake is applied. The error is signaled immediately. The
ready signal is revoked and the error output is set, if programmed. A restart is only possible
after an error reset has been performed during which the inverter is reinitialized.
RAPID
STOP/FAULT
The drive is braked with the set stop ramp t13/t23. Once the stop speed is reached, the
output stage is inhibited and the brake is applied. The error is signaled immediately. The
ready signal is revoked and the error output is set, if programmed. A restart is only possible
after an error reset has been performed during which the inverter is reinitialized.
IMM.
STOP/WARN.
The inverter performs an immediate switch-off and an error is signaled. The output stage is
inhibited and the brake is applied. The error is signaled via the terminal, if programmed.
The ready signal is not revoked. The drive restarts without unit re-initialization if the error is
rectified by an internal procedure or by an error reset.
EMERG. STOP/
WARNG
The drive is braked with the emergency ramp t14/t24. Once the stop speed is reached, the
output stage is inhibited and the brake applied. The error is signaled immediately. The error
is signaled via the terminal, if programmed. The ready signal is not revoked. The drive
restarts without unit re-initialization if the error is rectified by an internal procedure or by an
error reset.
RAPID
STOP/WARNG
The drive is braked with the set stop ramp t13/t23. Once the stop speed is reached, the
output stage is inhibited and the brake applied. The error is signaled immediately. The error
is signaled via the terminal, if programmed. The ready signal is not revoked. The drive
restarts without unit re-initialization if the error is rectified by an internal procedure or by an
error reset.
