Function
The output speed is higher than the setting in parameter 4-53
Warning Speed High.
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 thermis-
tor.
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.
The brake is active, and there are no warnings.
The brake is ready for operation, and there are no faults.
The output is logic 1 when the brake IGBT is short-circuited. Use
this fraction to protect the drive if there is a fault on the brake
modules. To cut out the main voltage from the drive, use the out-
put/relay.
The relay is activated when [0] Control word is selected in para-
meter group 8-** Communications and Options.
Indicates that the Safe Torque Off (STO) on terminal 37 is acti-
vated.
Active when the actual speed is outside the settings in
parameter 4-54 Warning Reference Low and parameter Warning
Reference High.
Active when the actual speed is below the speed reference set-
ting.
Active when the actual speed is above the speed reference set-
ting.
