Programming
[16] Below speed, Output speed is lower than the setting in
low 4-52 Warning Speed Low.
[17] Above speed, Output speed is higher than the setting in
high 4-53 Warning Speed High.
[18] Out of Feedback is outside the range set in
feedback 4-56 Warning Feedback Low and
range 4-57 Warning Feedback High.
[19] Below Feedback is below the limit set in
feedback low 4-56 Warning Feedback Low.
[20] Above Feedback is above the limit set in
feedback high 4-57 Warning Feedback High.

[22] Ready, no The frequency converter is ready for
thermal operation and there is no overtemperature
warning warning.
[23] Remote, The frequency converter is ready for

warning
[24] Ready, no The frequency converter is ready for
over-/ under operation and the mains voltage is within
voltage the specified voltage range (see
chapter 11 Specifications).
[25] Reverse Reversing. Logic '1' when CW rotation of
the motor. Logic '0' when CCW rotation of
the motor. If the motor is not rotating the
output follows the reference.
[26] Bus OK Active communication (no time-out) via
the serial communication port.
[27] Torque limit Use in performing a coasting stop and in
and stop 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 Brake is active and there are no warnings.
brake warning
[29] Brake ready, Brake is ready for operation and there are
no fault no faults.
[30] Brake fault Output is logic '1' when the brake IGBT is
(IGBT) 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.
[31] Relay 123 Relay is activated when control word [0] is
selected in parameter group 8-**
Communications and Options.
[32] Mechanical Enables control of an external mechanical
brake control brake, see description in chapter 6.1.3 2-2*

[45] Bus Ctrl Controls output via bus. The state of the
output is set in 5-90 Digital & Relay Bus
Control. The output state is retained in the
event of bus time-out.
[46] Bus Ctrl On at Controls output via bus. The state of the
timeout output is set in 5-90 Digital & Relay Bus
Control. If bus time-out the output state is
set high (On).
[47] Bus Ctrl Off at Controls output via bus. The state of the
timeout output is set in 5-90 Digital & Relay Bus
Control. If bus time-out the output state is
set low (Off).
[51] MCO Active when an MCO 302 or MCO 305 is
controlled connected. The output is controlled from
option.
[55] Pulse output
[60] Comparator 0 See parameter group 13-1* Comparators. If
comparator 0 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[61] Comparator 1 See parameter group 13-1* Comparators. If
comparator 1 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[62] Comparator 2 See parameter group 13-1* Comparators. If
comparator 2 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[63] Comparator 3 See parameter group 13-1* Comparators. If
comparator 3 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[64] Comparator 4 See parameter group 13-1* Comparators. If
comparator 4 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[65] Comparator 5 See parameter group 13-1* Comparators. If
comparator 5 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[70] Logic Rule 0 See parameter group 13-4* Logic Rules. If
logic rule 0 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[71] Logic Rule 1 See parameter group 13-4* Logic Rules. If
logic rule 1 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
[72] Logic Rule 2 See parameter group 13-4* Logic Rules. If
logic rule 2 is evaluated as TRUE, the
output goes high. Otherwise, it is low.
