IMO iDrive EDX 100V series 1-ph/0.2 – 0.75kW (0.25 – 1HP) Owner's Manual page 47

A08 V/F Base Voltage
A09 V/F Base Frequency
In example below: A09 = 50Hz, b04 =100%
If A08 setting is 200~240V, then output voltage for the pattern:
240
220
200
The iDrive output voltage cannot exceed its input voltage.
A10 V/F Torque Boost Gain 00.0 – 30.0%
A11 Electronic thermal overload protection
for motor (OL1) :
Set A11 = 000 and b09 to rated motor current (Amps) to give correct thermal overload protection.
A12 Advanced parameter
functions display
A12 = 000. Parameter group 'b' cannot be displayed or accessed.
A12 = 001. Enable display and access parameter group 'b' .
A08 = 240
A08 = 220
A08 = 200
