Configuring Drive 
Parameters
3–55
06 FA3 Frequency arrival type 
3 – at frequency
ON when output to motor is at the FA threshold 1 (C042) 
during accel, or at C043 during decel
OFF when the output to motor is not at either the FA 
threshold 1 (C042) during accel or at C043 during 
decel
07 OTQ Over-torque signal ON when the over-torque feature is enabled and the motor 
is generating excess torque
OFF when the over-torque feature is disabled or the motor 
is not generating excess torque
08 IP Instantaneous power 
failure signal
ON when the inverter input power has decreased below 
the acceptable input voltage level
OFF when the inverter input power is within rated range
09 UV Under-voltage signal ON when the inverter input power has decreased below 
the acceptable input voltage level
OFF when the inverter input power is within rated range
10 TRQ In torque limit ON when the output torque exceeds level set for the 
particular torque/frequency quadrant in effect during 
operation
OFF when the output torque is less than the level set for the 
operating quadrant
11 RNT Operation time over ON when the inverter Run time exceeds the limit set by 
Run/power-on warning time (B034)
OFF when the inverter Run time is less than the limit set by 
Run/power-on warning time (B034)
12 ONT Plug-in time over ON when the inverter plug-in time exceeds the set limit
OFF when the inverter plug-in time is less than the limit
13 THM Thermal alarm signal ON when the thermal limit for the motor is exceeded
OFF when the thermal limit is not exceeded
19 BRK Brake release signal ON when the inverter signals the external braking system 
to release (open) its brake
OFF when the inverter is not driving the motor, and needs 
the external brake engaged
20 BER Brake error signal ON when the output current is less than the set releasing 
current
OFF when the braking function is not in use, or when the 
output current to the motor is correct and it is safe to 
release the brake
21 ZS Zero speed detect ON when the encoder pulses of the motor has stopped
OFF when motor rotation causes encoder pulses
22 DSE Speed deviation 
maximum
ON when the velocity error exceeds the error threshold 
defined for the encoder input
OFF when the velocity error is less than the error threshold 
defined for the encoder input
