4 SHORT CIRC Fault current. Check for and correct:
• A short-circuit in the motor cable(s) or motor.
• Supply disturbances.
5
REVERSED Not used.
6 DC UNDERVOLT Intermediate circuit DC voltage is not sufficient. Check for and correct:
• Missing phase in the input power supply.
• Blown fuse.
• Undervoltage on mains.
7
AI1 LOSS Analog input 1 loss. Analog input value is less than AI1FAULT LIMIT (3021).
Check for and correct:
• Source and connection for analog input.
• Parameter settings for
AI1FAULT LIMIT (3021) and 3001 AI<MIN FUNCTION.
8
AI2 LOSS Analog input 2 loss. Analog input value is less than AI2 FAULT LIMIT (3022).
Check for and correct:
• Source and connection for analog input.
• Parameter settings for AI2 FAULT LIMIT (3022) and 3001 AI<MIN FUNCTION.
9 MOT OVERTEMP Motor is too hot, based on either the drive’s estimate or on temperature
feedback.
• Check for overloaded motor.
• Adjust the parameters used for the estimate (3005…3009).
• Check the temperature sensors and Group 35 parameters.
10
PANEL LOSS Panel communication is lost and either:
• Drive is in local control mode (the control panel displays LOC), or
• Drive is in remote control mode (REM) and is parameterized to accept
start/stop, direction or reference from the control panel.
To correct check:
• Communication lines and connections
• Parameter 3002
PANEL COMM ERR.
• Parameters in Group 10: Command Inputs and Group 11: Reference
Select (if drive operation is REM).
11
REVERSED Not used.
12 MOTOR STALL Motor or process stall. Motor is operating in the stall region. Check for and
correct:
• Excessive load.
• Insufficient motor power.
• Parameters 3010…3012.
13
RESERVED Not used.
