This alarm usually stems from a mismatch between the drive’s expected motor current and the actual current drawn when the brake should be released.

The root cause of error code 2563 lies in the physical failure of a critical electronic component on the drive's circuit boards. Based on user experience and common failure patterns for VLT drives, several components are possible culprits:
A physical safety device connected to the interlock terminal—such as an emergency stop, fire safety switch, or fan damper limit switch—has opened.
Go to and Parameter 15-60 to 15-63 (Option Ident) .
: If the "Position Error Tolerance" (parameter group 37-**) is set too tightly, even minor deviations will trip the alarm. Encoder Issues
Inspect the motor connections in the motor junction box for moisture, corrosion, or loose wires. Ensure the motor cables are not damaged along their run. 4. Check Current Sensors (Hall Sensors)
Follow these steps in order to diagnose and resolve the issue: 1. Verify Brake Functionality
This error means the drive’s processor cannot read or write data to the memory correctly. It is a critical fault, often putting the drive into a trip state, meaning it cannot operate until the issue is resolved and the alarm is cleared. Key Indicators of Error 2563 The drive shuts down (trips). The keypad displays "Alarm 2563" or "Error 2563". The drive may not respond to reset commands initially. Common Causes for Alarm 2563
Unseat and cleanly snap back any fieldbus options (A, B, or C option modules) embedded into the control board. 3. Execute a Manual Drive Initialization
Inspect the pins on the control card and the receptacle on the option module for dust, corrosion, or bent pins.
Check that internal ribbon cables are routed well away from the drive’s high-power AC output phases to prevent inductive cross-talk. Step 4: Validate the 24V DC Internal Supply
(Overcurrent) from a jammed roller. He knew those by heart. But today, the Local Control Panel stared back at him with an impossible sequence: ALARM 2563
Clean dust accumulations using specialized electronics cleaner and lint-free swaps. Reinsert firmly until the module clicks flat against the primary PCB. Step 3: Audit EMI Mitigation and Shielding
Once the fault is isolated, take the following actions to clear the 2563 error: *
