[25] Reverse
Reversing. Logic ‘1’ =
relay activated, 24 V DC when CW rotation of the motor. Logic ‘0’ = relay not
activated, no signal, when CCW rotation of the motor.
[26] Bus OK Active communication (no time-out) via the serial communication port.
[27] Torque limit and stop Use in performing a coasting stop and in torque limit condition. If the frequency converter has
received a stop signal and is at the torque limit, the signal is Logic ‘0’.
[28] Brake, no warning The brake is active and there are no warnings.
[29] Brake ready, no fault The brake is ready for operation and there are no faults.
[30] Brake fault (IGBT) The output is Logic ‘1’ when the brake IGBT is short-circuited. Use this function to protect the
frequency converter if there is a fault on the brake modules. Use the output/relay to cut out the
main voltage from the frequency converter.
[35] External Interlock External Interlock function has been activated via one of the digital inputs.
[40] Out of ref range
[41] Below reference low
[42] Above reference high
[45] Bus Ctrl
[46] Bus Ctrl 1 if timeout
[47] Bus Ctrl 0 if timeout
[55] Pulse output
[60] Comparator 0 See par. group 13-1*. If Comparator 0 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[61] Comparator 1 See par. group 13-1*. If Comparator 2 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[62] Comparator 2 See par. group 13-1*. If Comparator 2 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[63] Comparator 3 See par. group 13-1*. If Comparator 3 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[64] Comparator 4 See par. group 13-1*. If Comparator 4 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[65] Comparator 5 See par. group 13-1*. If Comparator 5 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[70] Logic Rule 0 See par. group 13-4*. If Logic Rule 0 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[71] Logic Rule 1 See par. group 13-4*. If Logic Rule 1 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[72] Logic Rule 2 See par. group 13-4*. If Logic Rule 2 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[73] Logic Rule 3 See par. group 13-4*. If Logic Rule 3 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[74] Logic Rule 4 See par. group 13-4*. If Logic Rule 4 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
[75] Logic Rule 5 See par. group 13-4*. If Logic Rule 5 is evaluated as TRUE, the output will go high. Otherwise, it
will be low.
