Trip
Brake R Too Hot
Braking resistor overload timed out (I
The Brake R Too Hot indicates that braking resistor overload has timed out. The value in Braking Resistor Thermal
Accumulator (D17) is calculated using Braking Resistor Rated Power (D15) rating, Braking Resistor Thermal Time
Constant (D16) and Braking Resistor Resistance (D18) value. The Brake R Too Hot trip is initiated when Braking Resistor
Thermal Accumulator (D17) reaches 100 %.
Recommended actions:
19
•
Ensure the values entered into the braking resistor overload protection parameters D14, D15 and D17 are correct
•
Check the correct braking resistor is being used for the drive model and system
•
Check the motor regenerative loading
•
Check the Elevator is balanced correctly
•
If external thermal protection is being used for the braking resistor, and the internal software brake resistor overload
protection is not required, set parameter D14, D15 and D17 = 0 to disable the protection and trip.
NV Media Card Write fail
Card Access
The Card Access trip indicates that the drive was unable to access the NV Media Card.
•
If the trip occurs during the data transfer to the NV Media Card then the file being written may be corrupted.
•
If the trip occurs when the data is being transferred to the drive then the data transfer may be incomplete.
If a parameter file is transferred to the drive and this trip occurs during the transfer, the parameters are not saved to non-
185
volatile memory, and so the original parameters can be restored by powering the drive down and up again.
Recommended actions:
•
Check NV Media Card is installed / located correctly
•
Replace the NV Media Card
Card Boot
The User Menu A parameter modification cannot be saved to the NV Media Card
User Menu A changes are automatically saved on exiting edit mode.
The Card Boot trip will occur if a write to a User Menu A parameter has been initiated via the keypad by exiting edit mode
and Parameter Cloning (N01) modes is set for auto or boot mode, but the necessary boot file has not been created on the
NV Media Card to take the new parameter value. This occurs when Parameter Cloning (N01) modes is changed to Auto (3)
177
or Boot (4) mode, but the drive is not subsequently reset.
Recommended actions:
•
Ensure that Parameter Cloning (N01) is correctly set, and then reset the drive to create the necessary file on the NV
Media Card.
•
Re-attempt the parameter write to the User Menu A
Card Busy
NV Media Card cannot be accessed as it is being accessed by an option module
The Card Busy trip indicates that an attempt has been made to access a file on NV Media Card, but the NV Media Card is
already being accessed by an option module, such as one of the Applications modules. No data is transferred.
178
Recommended actions:
•
Wait for the option module to finish accessing the NV Media Card and re-attempt the required function
Card Data Exists
NV Media Card data location already contains data
The Card Data Exists trip indicates that an attempt has been made to store data on a NV Media Card in a data block which
already contains data.
179
Recommended actions:
•
Erase the data in the data block to allow save
•
Write data to an alternative data block
Card Compare
NV Media Card file/data is different to the one in the drive
A compare has been carried out between the drive and a file on the NV Media Card, a Card Compare trip is initiated if the
parameters on the NV Media Card are different to the drive.
188
Recommended actions:
•
Set Pr mm00 to 0 and reset the trip
•
Check to ensure the correct data block on the NV Media Card has been used for the compare
Card Drive Mode
NV Media Card parameter set not compatible with current drive mode
The Card Drive Mode trip is produced during a compare if the drive mode in the data block on the NV Media Card is
different from the current drive mode. This trip is also produced if an attempt is made to transfer parameters from a NV
Media Card to the drive if the operating mode in the data block is outside the allowed range of operating modes.
187
Recommended actions:
•
Ensure the destination drive supports the drive operating mode in the parameter file.
•
Clear the value in Pr mm00 and reset the drive
•
Ensure the destination drive operating mode is the same as the source parameter file
