OVERSPEED
Possible Reason for Trip
• Trying to decelerate a large inertia too quickly or too often
Internal dynamic braking switch has been overloaded:
• Trying to decelerate a large inertia too quickly or too often
Keypad has been disconnected from drive whilst drive is running in Local Control:
• GKP accidentally disconnected from drive
Lost option communications:
• A break in option communications has been detected. Refer to option
communications manual.
• The Line contactor failed to connect.
Missing 3-phase line supply
•
• Indicates a missing input phase, for Frame K drives.
The DC link ripple voltage is too high:
• Check for a missing input phase
Repetitive start / stop or forward reverse action.
•
Lost Base Modbus communications:
A break in the Base Modbus communications has been detected. Refer to
•
"Appendix A Modbus TCP".
24V rail is low
Output overload due to excess current being drawn from the 24v terminal.
•
Only for PMAC motor : When using the Start feature in Sensorless Vector Control, the
real speed hasn't reached the speed setpoint after 5 seconds to move from open to
closed loop control or to move from closed to open loop
Overspeed:
>150% base speed when in Sensorless Vector mode
•
Criteria for Warning
The power calculation for the
external resistor has exceeded
one half of the Brake Overrating
allowance.
The power calculation for the
internal dynamic braking switch
has exceeded one half of the its
overrating allowance.
