Positioning Control
5-40 Function Relay
Option: Function:
[11] At torque limit The torque limit set in 4-16 Torque
Limit Motor Mode or 4-17 Torque
Limit Generator Mode has been
exceeded.
[12] Out of current range The motor current is outside the
range set in 4-18 Current Limit.
[13] Below current, low The motor current is lower than set
in 4-50 Warning Current Low.
[14] Above current, high The motor current is higher than set
in 4-51 Warning Current High.
[15] Out of frequency The output speed/frequency exceed
range the set in 4-40 Warning Freq. Low
and 4-41 Warning Freq. High.
[16] Below frequency, The output frequency is lower than
low the setting in 4-40 Warning Freq.
Low.
[17] Above frequency, The frequency is higher than the
high setting in 4-41 Warning Freq. High.
[18] Out of feedb. range The feedback is outside the range
set in 4-56 Warning Feedback Low
and 4-57 Warning Feedback High.
[19] Below feedback, low The feedback is below the limit set
in 4-56 Warning Feedback Low.
[20] Above feedback, The feedback is above the limit set
high in 4-57 Warning Feedback High.
[21] Thermal warning Thermal warning turns on when the
temperature exceeds the limit wither
in motor, frequency converter, brake
resistor or connected resistor.
[22] Ready, no thermal The frequency converter is ready for
warning operation and there is no overtem-
perature warning.
[23] Remote,ready,no TW The frequency converter is ready for
operation and is in Auto On mode.
There is no overtemperature
warning.
[24] Ready, no over-/ The frequency converter is ready for
under voltage operation, and the mains voltage is
within the specified voltage range.
[25] Reverse The motor runs (or is ready to run)
clockwise when logic=0 and
counterclockwise when logic=1. The
output changes as soon as the
reversing signal is applied.
[26] Bus OK Active communication (no time-out)
via the serial communication port.
[27] Torque limit & stop Use for performing a coasted stop
and frequency converter in torque

Function:
limit condition. If the frequency
converter has received a stop signal
and is in torque limit, the signal is
logic=0.
The brake is active and there are no
warnings.
there are no faults.
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 module. Use the
digital output/relay to cut out the
mains voltage from the frequency
converter.
Digital output/relay is activated
when [0] Control word is selected in
parameter group 8-** Communi-
cations.
Selection of mechanical brake
control. When selected parameters
in parameter group 2-2* Mechanical
brake are active. 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.
Activate relay 1 by a control word
from the fieldbus. No other
functional impact on the frequency
converter. Typical application:
Controlling an auxillary device from
a fieldbus. The function is valid
when [0] FC Profile is selected in
8-10 Control Word Profile.
Activate relay 2 by a control word
from the fieldbus. No other
functional impact on the frequency
converter. Typical application:
Controlling an auxillary device from
a fieldbus. The function is valid
when [0] FC Profile is selected in
8-10 Control Word Profile.
Active when the actual speed is
outside the settings in 4-55 Warning
Reference High and 4-56 Warning
Feedback Low.
