[20] Above feedback high The feedback is above the limit set in par. 4-57 Warning Feed-
back High
.
[21] Thermal warning The thermal warning turns on when the temperature exceeds
the limit in the motor, the frequency converter, the brake resis-
tor, or the thermistor.
[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 communica-
tion port.
[27] Torque limit and stop Used 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 4 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.
