Function
The drive is ready for operation and is in auto-on mode. There is
no overtemperature warning.
The drive is ready for operation and the mains voltage is within
the specified voltage range.
The motor runs (or is ready to run) clockwise when logic = 0 and
runs counterclockwise when logic = 1. The output changes when
the reversing signal is applied.
Active communication (no timeout) via the serial communication
port.
Used for coast stop and in torque limit conditions. If the drive has
received a stop signal and is at the torque limit, the signal is logic
0.
Brake is active, and there are no warnings.
Brake is ready for operation and there are no faults.
Output is logic 1 when the brake IGBT is short-circuited. Use this
function to protect the drive if there is a fault on the brake mod-
ules. To cut out the main voltage from the drive, use the out-
put/relay.
Relay is activated when [0] Control Word is selected in parameter
group 8-** Communications and Options.
Enables control of an external mechanical brake. For more infor-
mation on mechanical brake control, refer to the drive-specific
design guide.
Indicates that the Safe Torque Off on terminal 37 is activated.
Active when the actual speed is outside settings in parameter
4-52 Warning Speed Lowand in parameter 4-55 Warning
Reference High.
Active when the actual speed is below speed reference setting.
Active when the actual speed is above speed reference setting.
Controls output via bus. The state of the output is set in
parameter 5-90 Digital & Relay Bus Control. If a bus timeout
occurs, the output state is retained.
