A0 – Od
Î
Over Discharge
When showing
Od
presents the discharge time exceeds the setting in parameter
Pr.151 (Over Discharge Protect Time).
z
Check the setting of Pr.151 is proper or not. If the setting is too short, it is easily to
cause alarm. To set it for longer time, should consider if the resistor’s wattage is
enough or not.
z
Check the load of motor. Is the inertia too large to generate great feed back
energy?
z
Check the input power voltage of driver. Is the voltage exceeds the rating of
input?
z
Check if the setting of Pr.130 (Input Power Voltage) is suitable or not.
z
Check if the displayed message of Pr.132 (DC Bus Voltage) is correct or not?
z
According to the result of last 3 check items to decide if there is necessary to
modify the setting of Pr.131 (DC Bus Measurement Adjust).
A0 – OL
Î
Motor Over Load
When showing
OL
presents the motor is over load. The over load protection is
executed by the internal electronic thermo relay. When the accumulate thermo time
exceeds the setting value, the driver will trip and show this message.
z
Check the setting of Pr.215 (Electronic Thermo Relay Time) is proper or not.
z
Check the setting of Pr.210 (Motor Full Load Current Ratio) is correct or not.
z
Check the setting of r Pr.211 (Motor Exciting Current Ratio) is correct or not.
z
Check if the motor is stalled.
z
Check if the load exceeds the rating of motor.
z
Check if the variant of load exceeds the design specification.
A0 – OH
Î
Heat Sink Over Heat or External Over Heat Protect
When showing
OH
presents the heat sink temperature exceeds the setting of Pr.150
(Over Heat Protect Temperature) or there is an external over heat protect signal
happened.
z
Check if the setting of Pr.150 (Over Heat Protect Temperature) is proper or not.
z
Set the Pr.146 (Fan Control Type) = 1 to check the fan function. If the fan is out of
working, replace it.
z
Check if the fan is stalled.
z
Check if the condition of driver fit in the installation environment.
z
Check if the ambient temperature exceeds the installation environment.
z
The temperally variation of climate may cause ambient temperature to be high,
arranging a proper cooling method to prevent over heat contition is necessary at
this moment.
