Description
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 counterclockwise when logic
= 1. The output changes as soon as the reversing signal is applied.
Active communication (no timeout) via the serial communication port.
Use for performing a coasted stop in a torque limit condition. If the drive has received a stop
signal and is in 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 module. Use the digital output/relay to cut out the main voltage
from the drive.
Digital output/relay is activated when [0] Control Word is selected in parameter group 8-**
Comm. and Options.
Selection of mechanical brake control. When selected parameters in parameter group 2-2* Me-
chanical Brake are active. The output must be reinforced to carry the current for the coil in the
brake. Usually solved by connecting an external relay to the selected digital output.
Indicates that the Safe Torque Off on terminal 37 has been activated.
Activate relay 1 by control word from fieldbus. No other functional impact in the drive. Typical
application: Controlling auxiliary device from fieldbus. The function is valid when [0] FC profile
in parameter 8-10 Control Word Profile is selected.
Activate relay 2 by control word from fieldbus. No other functional impact in the drive. Typical
application: Controlling auxiliary device from fieldbus. The function is valid when [0] FC profile
in parameter 8-10 Control Word Profile is selected.
Failure in the speed feedback loop from motor running in closed loop. The output can eventu-
ally be used to prepare switching the drive in open loop in an emergency case.
When the difference between calculated speed and actual speed in parameter 4-35 Tracking
Error is larger than selected, the digital output/relay is active.
Active when the actual speed is outside the settings in parameter 4-52 Warning Speed Low to
parameter 4-55 Warning Reference High.
Active when the actual speed is below speed reference setting.
Active when actual speed is above speed reference setting.
Controls digital output/relay via bus. The state of the output is set in parameter 5-90 Digital &
Relay Bus Control. The output state is retained in the event of bus timeout.
Controls output via bus. The state of the output is set in parameter 5-90 Digital & Relay Bus Con-
trol. 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 Con-
trol. If a bus timeout occurs, the output state is set low (Off).
