Code Modbus ID Parameter Application RO/RW
P5.1.10 288 Switching Frequency 1,2,3 RW
This parameter sets the frequency that the PWM wave rides on, higher switching frequency will be cleaner
the output sine wave, lower switching frequency will be a choppier sine wave. Motor noise can be minimized
using a high switching frequency but the amount of heat dissipation increases. Increasing the switching
frequency reduces the capacity of the frequency converter unit.
For protection against thermal overload, the switching frequency automatically is reduce in the fact that the
ambient temperature is high as well as high load currents.
Note: See Installation Manual for the values listed for the individual frame size switching frequency ranges.
It also provides de-rating tables required for sizing.
P5.1.11 1665 Sine Filter Enable 1,2,3 RW
This parameter is used when a sine filter is connected to the output motor leads, the parameter is used to
lock in the thermal management controls to not decrease the Switching frequency.
P5.1.12 294 OverVoltage Control 1,2,3 RW
This parameters allow the overvoltage controllers to be switched out of operation. This may be useful, for
example, if the main supply voltage varies more than –15% to +10% and the application will not tolerate
this overvoltage. In this case, the regulator controls the output frequency taking the supply fluctuations into
account.
0 = Controller switched off
1 = Controller switched on
P5.1.13 298 Load Drooping 3 RW
This parameter is used to enable speed drop as a function of the load, used to share loads between
mechanically coupled motors. This parameter corresponds to the nominal torque of the motor.
Example: If load drooping is set to 10% for a motor that has a nominal frequency of 50Hz and is nominally
loaded (100% of torque) the output frequency is allowed to decrease 5Hz from the frequency reference.
Thefunction is used for e.g. when balanced load is needed for mechanically connected motors.
P5.1.14 1630 Droop Control Filter Time Constant 3 RW
Filter time when using droop control
P5.1.15 2835 Overmodulation Enable 1,2,3 RW
When enabled, this parameter increases the output voltage under low input voltage.
NOTE: May increase harmonics and lead to instability.
P5.2.1 577 Motor Nom Current 2 2,3 RW
Use this parameter to set the second motor set name plate Current. Selected based off of a digital input.
P5.2.2 578 Motor Nom Speed 2 2,3 RW
Use this parameter to set the second motor set name plate RPM. Selected based off of a digital input.
P5.2.3 579 Motor PF 2 2,3 RW
Use this parameter to set the second motor set name plate Power Factor. Selected based off of a
digital input.
P5.2.4 580 Motor Nom Volt 2 2,3 RW
Use this parameter to set the second motor set name plate Voltage. Selected based off of a
digital input.
P5.2.5 581 Motor Nom Freq 2 2,3 RW
Use this parameter to set the second motor set name plate Frequency. Selected based off of a
digital input.
P5.2.6 1656 VF Stable Kd 1,2,3 RW
Expert control parameter for drive stability. This should only be changed after review and suggestion
of an Eaton engineer.
P5.2.7 1657 VF Stable Kq 1,2,3 RW
Expert control parameter for drive stability. This should only be changed after review and suggestion
of an Eaton engineer.
P6.1.1 308 Output Phase Fault 1,2,3 RW
Use this parameter to set the device reaction to a “Phase Loss Output” condition. This failure could be
devicedependent.
0 = No response
1 = Warning
2 = Fault, stop mode after fault according to standard stop mode
3 = Fault, stop mode after fault always by coasting
