B_32: Reactive current setting
– The inverter’s D_02 monitor function displays the
motor current. The display accuracy is normally ±20%, provided that the following
conditions exist:
• A single motor with standard frame size and characteristics is connected
• The inverter’s output frequency is at 50% or higher of the maximum output frequency
• The inverter’s output current is within the rated current
However, it will be necessary to calibrate the display accuracy via B_32 adjustment of
the internal no-load reactive motor current if any of these conditions exist:
• The motor is smaller than the standard maximum recommended for the inverter
• The motor is a two-pole motor type
• Two or more motors are connected in parallel to the inverter (be sure to multiply the
current by the number of motors when setting B_32)
For general purpose motors that have an undetermined internal no-load (reactive) motor
current, use the following table for typical current values. For special motors, consult the
manufacturer of your particular motor.
