[21] Thermal warning Thermal warning turns on when the temperature exceeds the limit either in motor, adjustable fre-
quency drive, brake resistor, or connected thermistor.
[22] Ready,no thermal W The adjustable frequency drive is ready for operation and there is no overtemperature warning.
[23] Remote,ready,no TW The adjustable frequency drive is ready for operation and is in auto on mode. There is no overtem-
perature warning.
[24] Ready, voltage OK The adjustable frequency drive is ready for operation and the AC line voltage is within the specified
voltage range (see General Specifications section in the Design Guide).
[25] Reverse Logic ‘1’ when CW rotation of the motor. Logic ‘0’ when CCW rotation of the motor. If the motor is
not rotating, the output will follow the reference.
[26] Bus OK Active communication (no timeout) via the serial communication port.
[27] Torque limit stop Use in performing a coasted stop and adjustable frequency drive in torque limit condition. If the
adjustable frequency drive has received a stop signal and is at the torque limit, the signal is Logic
‘0’.
[28] Brake: No Brake War Brake is active and there are no warnings.
[29] Brake ready, no fault Brake is ready for operation and there are no faults.
[30] Brake fault (IGBT) Output is Logic ‘1’ when the brake IGBT is short-circuited. Use this function to protect the adjustable
frequency drive if there is a fault on the brake module. Use the digital output/relay to cut out the
AC line voltage from the adjustable frequency drive.
[31] Relay 123 Digital output/relay is activated when Control Word [0] is selected in parameter group 8-**.
[32] Mech brake ctrl Selection of mechanical brake control. When selected parameters in parameter group 2.2x are ac-
tive. 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.
[33] Safe stop active (FC 302 only) Indicates that the safe stop on terminal 37 has been activated.
[36] Control word bit 11 Activate relay 1 by control word from the serial communication bus. No other functional impact in
the adjustable frequency drive. Typical application: controlling auxiliary device from the serial com-
munication bus. The function is valid when FC profile [0] in par 8-10 is selected.
[37] Control word bit 12 Activate relay 2 FC 302 only) by control word from serial communication bus. No other functional
impact in the adjustable frequency drive. Typical application: controlling auxiliary device from the
serial communication bus. The function is valid when FC profile [0] in par 8-10 is selected.
[38] Motor feedb. error Failure in the speed feedback loop from motor running in closed-loop. The output can eventually
be used to prepare switching the drive in open-loop in emergency case.
[39] Tracking error When the difference between calculated speed and actual speed in par 4-35 is larger than selected,
the digital output/relay is active.
[40] Out of ref range Active when the actual speed is outside settings in par 4-52 to 4-55.
[41] Below reference, low Active when actual speed is below speed reference setting.
[42] Above ref, high Active when actual speed is above speed reference setting.
[43] Extended PID Limit
[45] Bus ctrl. Controls digital output/relay via bus. The state of the output is set in par. 5-90 ‘Digital & Relay Bus
Control’. The output state is retained in the event of bus timeout.
[46] Bus ctrl, 1 if timeout Controls output via bus. The state of the output is set in par. 5-90
Digital & Relay Bus Control
. In
the event of a bus timeout, the output state is set high (On).
