Intermediate circuit DC voltage is excessive. Check for and correct:
DC OVERVOLT
• Static or transient overvoltages in the input power supply.
• Insufficient deceleration time (parameters 2203
2206
DECELER TIME
• Undersized brake chopper (if present).
• Verify that overvoltage controller is ON (using parameter 2005).
Drive heatsink is overheated. Temperature is at or above limit.
DEV OVERTEMP
R1...R4 & R7/R8: 115 °C (239 °F)
R5/R6: 125 °C (257 °F)
Check for and correct:
• Fan failure.
• Obstructions in the air flow.
• Dirt or dust coating on the heat sink.
• Excessive ambient temperature.
• Excessive motor load.
Fault current. Check for and correct:
SHORT CIRC
• A short-circuit in the motor cable(s) or motor.
• Supply disturbances.
Not used.
RESERVED
Intermediate circuit DC voltage is not sufficient. Check for and correct:
DC UNDERVOLT
• Missing phase in the input power supply.
• Blown fuse.
• Undervoltage on mains.
1 Analog input 1 loss. Analog input value is less than
AI LOSS
Check for and correct:
• Source and connection for analog input.
• Parameter settings for
2 Analog input 2 loss. Analog input value is less than
AI LOSS
Check for and correct:
• Source and connection for analog input.
• Parameter settings for
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
parameters.
Panel communication is lost and either:
PANEL LOSS
• 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.
