FIO11B: Analog input and output (±10V / 4-20mA), no SBus

Same mounting position; mutually exclusive, cannot be installed together.

Especificações principais

Terminal wire gauge: Max 1.5mm² without ferrule; max 1.0mm² with ferrule

Bus cable: Par trançado blindado, standard CAN bus cable

Protocolos: MoviLink, CANopen, COSTURAR proprietary RS485

Instalação: Front slot of inverter. Must use original fixing screws to ensure EMC grounding.

Falhas Comuns

F43: RS485 communication timeout → Check shielding, rescisão, fiação, taxa de transmissão

F36: Missing option / Option mismatch → Confirm it is MC07B, module fully seated

CANopen node cannot go online: Check DIP termination resistor, endereço do nó, baud rate P884, P886

Nota de substituição

FSC11B is the standard option for CANopen communication on MC07B; there is no direct drop-in replacement. For PROFINET, other options such as the DFE series are required.

SEW FSC11B (MC07B) Installation and Commissioning Procedure

Prerequisites: All operations must be power-off; ESD protection required. FSC11B and FIO11B are mutually exclusive and cannot be fitted together. Only for MOVITRAC B MC07B inverters.

1. Instalação de hardware (Desligar)
2. Cut off power and wait for DC bus discharge (at least 5 minutos). Open the front cover of the inverter expansion compartment.
3. Tamanho do quadro 0 unidades: Fit standoffs first. Tamanho do quadro 1 and above come with standoffs pre-installed. Standoffs ensure high-frequency EMC grounding.
4. Align FSC11B with the slot and insert straightly. Tighten with the original screws (screws are critical for EMC grounding; do not omit).
5. Verify the board is fully seated without tilt or poor pin contact. Refit the cover.
6. DIP switch S1 setting (SBus/CAN bus termination resistor)

First and last inverter on the bus: S1 = ON (120Ω termination enabled)

All intermediate inverters: S1 = OFF (termination disabled)

Only two termination points are allowed on one SBus bus; all other stations must turn termination off, otherwise communication instability and packet loss will occur.

6. Fiação

X44: RJ10 maintenance port, PC commissioning only, cable ≤3m

X45: RS485 (ST11+ / ST12/ GND), SEW proprietary RS485, fixed 9.6k baud

X46: SBus CAN bus (SC11/SC12, SC21/SC22, pin7 24VIO)

Use shielded twisted pair. Shielding should be large-area crimped to inverter shield terminals; shield grounding at both ends of the bus, single-point grounding in the middle is recommended.

SC11/SC12 is one channel; SC21/SC22 is through-wiring for convenient daisy-chain connection.

7. Recheck wiring for short circuits and misconnection; ensure all node addresses are unique (1~63).
8. Pre-ower-on Check

Confirm power cable, motor cable and brake resistor wiring are correct

24V control supply healthy, no short circuit on the bus

No FIO11B in the same slot; inverter firmware supports FSC11B

Node ID and baud rate planned and unified for the whole network

3. Power On and Software Commissioning (MOVITOOLS MotionStudio)
4. Power on the inverter, connect PC to X44 RJ10 maintenance port (SEW USB-RJ10 commissioning cable)
5. Launch MOVITOOLS MotionStudio and scan devices. Normally MC07B + FSC11B option will be identified.

If scan fails: Check module seating, parafusos, or F36 fault (option detection failure)

3. Basic motor commissioning (perform motor identification first)

Enter the startup wizard, enter motor nameplate data and run static identification

4. Parâmetro	Descrição
   P884	SBus node address (1~63, unique across the network)
   P886	SBus baud rate (125k/250k/500k/1M), same for all devices
   P880	Control source selection: SBus/CANopen (bus control)
   P881	Setpoint source: SBus
   P887	SBus communication timeout (triggers F43 on timeout)

5. PDO Mapping (CANopen)

SEW standard PDO: TPDO (Inverter → PLC: Status word, actual speed, atual, fault code); RPDO (PLC → Inverter: Control word, speed setpoint)

Import the SEW standard EDS file into PLC configuration

6. Save parameters to the inverter (copy parameters to device). Power cycle once for parameters to take effect.
7. Bus Network Test
8. CANopen master scans the bus, all nodes online without heartbeat loss
9. No-load bus test: PLC sends control word (6 → 0F for enable), inverter ready
10. Jog test: Speed setpoint sent via bus, motor runs smoothly without oscillation or F43
11. Multi-motor synchronization: Same sync cycle and baud rate, check timing
12. Simulação de falhas: Disconnect bus to verify F43 and safe stop logic trigger at P887 timeout
13. Common Alarms and Troubleshooting

F36: Missing option / Option recognition error: Module not fully seated, loose screws, wrong model, faulty module

F43: SBus/RS485 communication timeout: Wrong termination resistor, taxa de transmissão incompatível, duplicate node ID, blindagem deficiente, bus short circuit, excessive cable length

Intermittent communication dropouts: Prioritize shielding grounding, DIP termination, separate routing of power and communication cables

6. Final Handover

Record node ID, baud rate and PDO configuration

Export parameter backup and EDS file for PLC engineer

Label each inverter with node number

SEW MC07B / MDX61B Inverter Common Fault Code List (Including FSC11B Communication Faults)

Redefinir métodos: Ciclo de energia, terminal reset, MOVITOOLS software reset. Fault history stored in P080. For all high-voltage inspection, cut off power and wait DC bus discharge ≥5 minutes.

2. Common Non-coded Abnormalities (Nenhum código de falha, Frequent On-site Issues)
3. No display after power on, tela preta

Missing 24V control supply, blown control fuse, damaged power board

Distinguir: Missing 380V main power or missing 24V control supply; MC07B can be powered only by 24V to check display

2. Display present, no enable, cannot start (digit shows 2)

No terminal enable signal; PLC does not send control word under bus control; P880/P881 source misselected

Local mode: start via panel; bus mode: confirm control source set to SBus/CANopen

3. Motor oscillation, unstable running, speed drift

Poor SBus/CANopen shielding and messy grounding; reversed encoder A/B phase; incomplete motor identification; load resonance

4. Intermittent F43 alarms

90% caused by termination resistor, shielding grounding, loose crimps; secondly, power cables routed in parallel with communication cables

5. Communication established but start/stop control fails

Wrong PDO mapping, control word bit definition error, PLC does not send 0Fh enable, inverter inhibited

3. Standard On-site Troubleshooting Sequence
4. Read fault code on display, check historical fault in P080
5. Classify: Power circuit faults (F01/F03/F06/F07/F11) / Communication option faults (F36/F43/F45) / Safety/motor protection (F31/F47/F84)
6. Check external wiring, tensão, isolamento, mechanics and cooling first; then parameters; finally judge hardware damage
7. For communication faults (FSC11B): Priority order: DIP termination → Node ID → Baud rate → Shielding grounding → Wiring topology
8. Reset Priority
9. Software reset (MOVITOOLS)
10. Terminal reset
11. Power off for more than 5 minutes and restart (full DC bus discharge)

Hardware damage faults (F01 module damage, F80, F98) will reoccur after reset

5. Summary of Key Communication Faults for FSC11B

F36: Inverter cannot recognize FSC11B (instalação, parafuso, falha de hardware)

F43: SBus/CANopen bus disconnection (fiação, rescisão, EU IA, taxa de transmissão, blindagem)

Bus scanned but frequent packet loss: Check shielding first; use daisy-chain only, avoid star wiring
