FU2-74: Gain for Motor Speed Display
This code is used to change the motor speed display to
rotating speed (r/min) or mechanical speed (m/min). The
display is calculated by following equation.
Rotating speed = 120 x F / P, where F=Output frequency,
P= motor pole number
Mechanical speed = Rotating speed x Motor RPM Display

FU2-75: DB (Dynamic Braking) Resistor Mode
Selection
This code is used to protect the DB resistor from over
heating.
Setting Range
LCD 7-Seg
Description
None
0
This is selected when there is no resistor
connected. At this time, inverter does not
generate DB turn on signal.
Int. DB-R
1
This is selected when using the internal
DB resistor. This must be selected for
1~5 HP inverters because they have
internal DB resistor as a default.
Enable Duty (%): 2 ~ 3 %
Continuous Turn On Time: 5 seconds
Ext. DB-R
2
This is selected when using an external
DB resistor. This must be selected for
7.5~10 HP inverters. This must be
selected for 1~5 HP inverters in case of
using an external DB resistor.
Enable Duty (%): 0 ~ 30 %
Continuous Turn On Time: 15 seconds
☞ The inverter turns the DB turn on signal OFF when the
Continuous Turn On Time expires during dynamic braking,
and an over voltage fault can occur. When this happens,
increase the deceleration time or install an external high-
duty DB resistor.
☞ Install an exterior high-duty DB resistor when the load
accelerates and decelerates frequently. Set the FU2-75 [DB
Resistor Mode selection] to ‘Ext. DB-R’, and set the FU2-76
[Duty of DB Resistor].
☞ This does not apply to 15~30 HP inverters. They need the
Optional DB unit to use DB resistor.
FU2-76: Duty of DB (Dynamic Braking) Resistor
This must be set when using an external DB resistor. The
