Functional Descriptions Chapter 1
The values of the four parameters Rated Frequency HMI Display Address (P371),
Motor Voltage HMI Display Address (P372), Actual Frequency HMI Display
Address (P373), and Motor Current HMI Display Address (P374) need not be
changed and can be left at their default values. The field support engineer can
change them according to the specific case.
Nameplate
This function is used to set the basic parameters of motor, drive, transformer, and
HECS. They are rated current, rated power, rated speed, rated power factor,
number of motor pole pairs, and so on.
Number of Power Cells Per Phase (P007) is the amount of power cells in one
phase.
For example, if the amount of power cells in one phase is five, then Number of
Power Cells Per Phase must be set to five. The number of power cell’s fault
information and warning information is based on Number of Power Cells Per
Phase. If Number of Power Cells Per Phase is set to zero, then all power cell’s fault
information and warning information is ignored. This allows the drive to be run
in low voltage. This function can be used for checking of low voltage components
and the control box.
Power Cell DC Bus Rated Voltage (P011) is the DC bus rated voltage of the
power cell. Motor Rated Current (P199) is used for the fault judgment related
motor current. The parameters Motor Rated Voltage (P012), Motor Rated Power
(P013), Motor Rated Speed (P014), Motor Rated Power Factor (P015), and
Number of Motor Pole Pairs (P017) are used for calculating the motor stator's
parameters.
Encoder Resolution (P019), Line CT Ratio (P195), and Line CT Burden Resistor
(P196). Motor HECS Ratio (P197) and Motor HECS Burden Resistor (P198) are
used to calculate the Hall current sensor's rated current, which is used for the
sampling of the drive's current (Line CT Ratio, Line CT Burden Resistor, Motor
HECS Ratio, and Motor HECS Burden Resistor are set based on the AT board
configuration).
The value of this parameter must be set to the actual amount used in each
phase.
