Note:
1.
Swing PWM uses 2.0 kHz carrier frequency as a base. Applying special PWM patterns minimizes
the audible noise of the motor.
2.
The upper limit for the carrier frequency is determined by drive capacity.

Drive Input Voltage Setting: E1-01
Set E1-01 according to the power supply voltage. This setting serves as a base value for certain
drive protective functions.
NOTICE: Set drive input voltage (not motor voltage) in parameter E1-01 for proper function of the protective
features of the drive. Failure to comply could result in improper drive operation. Set parameter E1-01 to match
the input voltage of the drive.

Set to the nominal voltage of the incoming line. Sets
the maximum and base voltage used by preset V/f
patterns (E1-03), and adjusts the levels of drive
protective features (e.g., overvoltage, braking resistor
level, stall prevention, etc.).
