Reset when
C6-01 is
changed.
<1> Available in drive software versions PRG: 1020 and later. Setting B uses a PWM pattern that reduces the amount
of leakage current detected over long wiring distances. This can help reduce alarm detection and problems with
the current monitor that result from leakage current over long wiring distances. This is the same as setting the
carrier frequency to 2 kHz.
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.

Setting
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.).
200 V Class: 155 to 255
400 V Class: 310 to 510
