Alarm string Description
Brake Resistor
Brake resistor overload. Parameter D16 Resistor thermal accumulator has reached 75.0 % of the value at which the drive
will trip.
Motor Overload
Parameter Motor Protection Accumulator (J26) has reached 75.0 % of the value at which the drive will trip and the load on
the drive is >100 %.
Drive Overload Drive over temperature. Percentage Of Drive Thermal Trip Level (J79) drive is greater than 90 %.
Autotune An autotune has been initialized and is in progress.
Upper row string Description Drive output
Inhibit
The drive is inhibited and cannot be run. The Safe Torque Off (STO), Drive enable signal is not applied to
control terminal T31.
Disabled
Ready
The drive is ready to run. The Drive enable is On, the drive is not active due to the drive run signal not
being present.
Disabled
Stop The drive is stopped / holding zero speed. Enabled
Run The drive is active and running. Enabled
Supply Loss Supply loss condition has been detected. Enabled

First row string Second row string Status
Booting Parameters Parameters are being loaded
Drive parameters are being loaded from a NV Media Card.
Booting Option Program User program being loaded
User program loading from a NV Media Card to a option module.
Writing To NV Card Writing data to NV Media Card
Data is being written to a NV Media Card to ensure that its copy of the drive parameters is correct because the drive is in Auto or Boot mode.
Waiting For Power System Waiting for power stage
Waiting for processor in power stage to respond following power-up.
Waiting For Options Waiting for an option module
Waiting for the options modules to respond after power-up.
Uploading From Options Loading parameter database
A power-parameter database is being updated because an option module has changed or because an applications module has requested changes
to the parameter structure.
