P810 sets the address of the MOVITRAC

B for communication via the serial
interface.
MOVITRAC
®
B units are always set to the address 0 on delivery. To avoid prob-
lems during data exchange in serial communication with several inverters,
SEW-EURODRIVE recommends that you do not use address 0.

Brake operation 1 / 2
P820/P821 lets you switch 4-quadrant operation on and off. 4-quadrant operation is possible if you connect a braking resistor to
MOVITRAC
®
B. P820/P821 must be set to OFF if there is no braking resistor connected to MOVITRAC
®
B, which means regenerative
operation is not possible. In this operating mode, the MOVITRAC
®
B unit attempts to extend the deceleration ramp. As a result, the
generated power is not too great and the DC link voltage remains below the switch-off threshold.
If the regenerative power becomes too great despite the extended deceleration ramps, then MOVITRAC
®
B may switch off with the
F07 DC link overvoltage
fault. In this case you have to extend the deceleration ramps manually (P131).
Therefore, do not set unreasonably short deceleration ramps!
The unit responds with fault
F34 Ramp/timeout
if the ramp is set too short and the ramp which can actually be achieved is significantly
longer than the set value.

Fault responses
The fault EXT. FAULT triggers ENABLED in inverter status only. P830 programs the fault response that is triggered by input terminal
programmed to /EXT. FAULT.
830
Response terminal "external
fault"
2 / Immediate stop/fault
The inverter performs an emergency stop with an error message. The
inverter inhibits the output stage and the brake is applied. The inverter
revokes the ready signal and sets the programmed fault output. A restart is
only possible after a fault reset has been performed during which the
inverter is reinitialized.
4 / Rapid stop / fault
(factory setting for P830)
The inverter brakes the drive at the specified stop ramp (P136/P146). The
inverter brakes with DC braking in 2-quadrant operation. Once the stop
speed is reached, the inverter inhibits the output stage and the brake is
applied. The fault is signaled immediately. The inverter revokes the ready
signal and sets the programmed fault output. A restart is only possible after
a fault reset has been performed during which the inverter is reinitialized.
7 / Rapid stop / warning
(factory setting for 833 / 836)
The fault response corresponds to STOP/FAULT, except the inverter does
not revoke the ready signal and the fault output is set.
833
Response to RS-485 timeout
836
Response to SBus timeout

Reset behavior
840
Manual reset
Parameter P840 corresponds to
the STOP/RESET key.
Yes
MOVITRAC
®
B resets the present fault. P840 automatically reverts to NO
after the reset. The motor immediately restarts to the specified setpoint if all
required signals are present after the reset has been performed. Activating
the manual reset does not have any effect if there is no fault present.
No
No reset.
No.
