Fault 12 Brake
Subfault: 12.1 Description: Brake output fault | ||
|---|---|---|
| Response: Application stop + output stage inhibit | |
Cause | Measure | |
No brake connected. | – Check the brake connection. – Check the startup. | |
Brake cable disconnected in switched-on state. | Check the connection of the brake. | |
The brake was overloaded by an overcurrent > 2 A. | – Make sure that the connected brake is permitted. – Check the brake. | |
The brake was overloaded by frequent connection (> 0.5 Hz). | Reduce the switching frequency of the brake. | |
Subfault: 12.2 Description: DC 24 V brake voltage not within permitted tolerance range | ||
|---|---|---|
| Response: Application stop + output stage inhibit | |
Cause | Measure | |
DC 24 V supply voltage not within permitted tolerance of 24 to 26.4 V. | Check the DC 24 V supply voltage. | |
Subfault: 12.3 Description: Brake temperature not within permitted range | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Brake temperature not within permitted range (too low or too high). | Check the ambient conditions and the application. | |
In the case of decentralized devices, the overvoltage of the DC link is dissipated via the brake. As a result, the temperature of the brake is too high. | Check the application for how often generator mode occurs. | |
Subfault: 12.4 Description: Brake control module missing | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Brake control has been activated although the device is not equipped with the matching module. | Select a different brake type or brake connection. | |
Subfault: 12.5 Description: Short circuit on the brake | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Short circuit in the brake. | Check the brake connection. | |
Subfault: 12.7 Description: Overcurrent in the brake | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The brake requires more current than the brake control electronics can supply. | – Check the parameterization of the brake. – Use suitable brake/brake control electronics. | |
Brake coil defective. | Replace the brake. | |
Subfault: 12.8 Description: Supply voltage fault | ||
|---|---|---|
| Response: Brake supply voltage fault | |
Cause | Measure | |
The fault can be caused as follows: – The supply voltage of the brake rectifier is outside the valid range. – The supply voltage of the brake rectifier is not available. | – Check the supply voltage. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
Subfault: 12.9 Description: Plausibility error | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
No brake connected. | Connect a brake. | |
Brake connected incorrectly. | Check and correct the brake connection. | |
Wrong brake was started up. | Check the startup. | |
Subfault: 12.20 Description: Digital motor integration – critical fault | ||
|---|---|---|
| Response: Output stage inhibit with self-reset | |
Cause | Measure | |
The intelligent brake rectifier of digital motor integration has detected a critical fault. | Observe the fault message of the subslave. Identify the exact cause of this fault message and take the appropriate measures to eliminate the fault. | |
Subfault: 12.21 Description: Digital motor integration – fault | ||
|---|---|---|
| Response: Emergency stop + output stage inhibit with self-reset | |
Cause | Measure | |
The intelligent brake rectifier of digital motor integration has detected a fault. | Observe the fault message of the subslave. Identify the exact cause of this fault message and take the appropriate measures to eliminate the fault. | |
Subfault: 12.22 Description: Digital motor integration – warning | ||
|---|---|---|
| Response: Warning with self-reset | |
Cause | Measure | |
The intelligent brake rectifier of digital motor integration signaled a warning. | Observe the warning of the subslave. Identify the exact cause of this warning and take the appropriate measures for elimination. | |
Subfault: 12.23 Description: Digital motor integration – timeout | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Communication with intelligent brake rectifier disrupted. | Check the connection. | |
Subfault: 12.24 Description: Digital motor integration – initialization error | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
Initialization of intelligent brake rectifier failed. | – Acknowledge the fault. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service. | |
