Function
Feedback is below the limit set in parameter 4-56 Warning Feedback Low and parameter 4-57
Warning Feedback High.
Feedback is below the limit set in parameter 4-56 Warning Feedback Low.
Feedback is above the limit set in parameter 4-57 Warning Feedback High.
The thermal warning turns on when the temperature exceeds the limit in the motor, the drive,
the brake resistor, or the thermistor.
The drive is ready for operation, and there is no overtemperature warning.
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 timenout) 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 modules. To cut out the main voltage from the drive, use the output/
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 information on mechanical brake con-
trol, 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 Low in parame-
ter 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.
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 set high (on).
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 set low (off).
