STBY I HIGH
Kone · Elevator Control
What does 1053 mean?
The motor controller (codes 1053, 2053, 3053) has detected high standby current. This indicates excessive current draw when the system should be idle. The specific lift reaction is controller dependent.
Common Causes
- Component leakage current within the controller or connected devices.
- Short circuit in a low power or auxiliary circuit.
- Internal controller fault causing unintended current draw.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Verify the motor controller's operational parameters, especially those related to idle state, standby current limits, and brake control settings, against the specified configuration.
- 2
Inspect all motor power cables, brake cables, and their connections between the controller and the motor/brake for signs of damage, chafing, loose terminals, or moisture ingress.
- 3
Measure the current draw on the motor controller's input power terminals or DC link while the system is in the standby state, comparing it to the specified nominal standby current.
- 4
Check for any unintended activation or partial short circuits in external components (e.g., motor brake, contactors, auxiliary loads) connected to the motor controller outputs during standby mode.
