A SEW‑EURODRIVE MOVITRAC B fitted with an FBG11B keypad may remain stopped when the keypad is displaying the external-control StoP screen. In the documented installation, changing the acceleration and deceleration ramps to 5 s did not restore operation. The drive started only after the operator selected and entered the keypad’s local-control menu.
Distinguish the Two StoP Displays
The FBG11B workflow includes two StoP contexts. The display without the local-control pictogram expects commands through the drive terminals. Because this installation had no auxiliary control wiring, that screen could not provide the requested keypad-only operation.
| Display context | Command source | Result in this installation |
|---|---|---|
| StoP without pictogram | External terminal commands | No start command was available |
| StoP with the bottom switch/drive pictogram | FBG11B keypad and potentiometer | RUN, STOP, and speed control operated |
Start the Drive from the FBG11B
- Use the arrow keys to move downward through the FBG11B menus until the bottom switch/drive pictogram appears.
- Press Enter to enter and activate that local-control menu. Merely highlighting its pictogram is insufficient.
- Press RUN to start and STOP to stop the motor.
- Use the keypad potentiometer for the requested speed reference.
If a fault is present, try the keypad Reset function first, then press RUN to resume. The evidence reports that most faults reset this way, while some require removal of drive power. One observed lockup cleared after the 230 V supply had been disconnected for half an hour, but the evidence does not establish that duration as a MOVITRAC requirement or prove that the action “clears memory.”
Verify Ramps, Motor Data, and Documentation
Set a ramp by selecting the acceleration or deceleration item, pressing Enter, changing the value with the arrow keys, pressing Enter again, and leaving with Out. A 5 s setting was tested without changing the no-start symptom, so do not treat the ramps as the primary cause when no command source is active.
The reported hardware was a MOVITRAC B MC07B0008-2B1-4-00, rated 0.75 kW, with an FBG11B. The test motor was rated 0.75 kW, 50 Hz, 240/420 V, 3.8/2.2 A, 1410 r/min, and power factor 0.74. The drive was configured for 240 V and 3.8 A while the motor terminal board was reported as star-connected. That combination requires verification against the motor connection diagram before operation; the evidence does not establish the correct terminal arrangement. Also verify keypad/manual compatibility: the drive was identified as a 2006 unit used with 2007 documentation, and the operator could not access the P07x information entries even with the LONG menu enabled.
FAQ
Why will my MOVITRAC B not start from the FBG11B keypad?
Select the bottom switch/drive pictogram and press Enter to activate local control. StoP without that pictogram expects an external terminal command.
Can a 5 second acceleration ramp prevent a MOVITRAC B from starting?
In this installation, changing both ramps to 5 s did not solve the no-start condition. The missing local-control selection was the effective cause.
What motor data was entered for the 0.75 kW MOVITRAC B test?
The entered values were 240 V and 3.8 A for a motor marked 240/420 V and 3.8/2.2 A. Because the terminal board was reported as star-connected, verify the motor diagram and actual connection before running.
