Group 64: Load Analyzer - Daikin MD5 Operation Manual

Group 64: Load Analyzer

This group defines the load analyzer, which can be used for analyzing the customer's process and sizing the drive and the motor.
The peak value is logged at 2 ms level, and the distribution loggers are updated on 0 .2 s (200 ms) time level . Three different values
can be logged .
1 . Amplitude logger 1: The measured current is logged continuously . The distribution as a percentage of the nominal current I2
is shown in ten classes .
2 . Peak value logger: One signal in group 1 can be logged for the peak (maximum) value . The peak value of the signal, peak
time (time when the peak value was detected) as well the frequency, current and DC voltage at the peak time are shown .
3 . Amplitude logger 2: One signal in group 1 can be logged for amplitude distribution . The base value (100% value) can be set
by the user .
The first logger cannot be reset. The other two loggers can be reset by a user defined method. They are also reset if either of the
signals or the peak value filter time is changed.

Code Description
6401 PVL SIGNAL
Defines (by number) the signal logged for the peak value.
• Any parameter number in
100 = NOT SELECTED – No signal (parameter) logged for the peak value .
101...178 – Logs parameter 0101...0178 .
6402 PVL FILTER TIME
Defines the filter time for peak value logging.
• 0 .0...120 .0 – Filter time (seconds) .
6403 LOGGERS RESET
Defines the source for the reset of peak value logger and amplitude logger 2.
0 = NOT SEL – No reset selected .
1 = DI1 – Reset loggers on the rising edge of digital input DI1 .
2...6 = DI2...DI6 – Reset loggers on the rising edge of digital input DI2...DI6 .
7 = RESET – Reset loggers . Parameter is set to NOT SEL .
-1 = DI1(INV) – Reset loggers on the falling edge of digital input DI1 .
-2...-6 = DI2(INV) ...DI6(INV) – Reset loggers on the falling edge of digital input DI2...DI6 .
6404 AL2 SIGNAL
Defines the signal logged for amplitude logger 2.
• Any parameter number in
100 = NOT SELECTED – No signal (parameter) logged for amplitude distribution (amplitude logger 2) .
101...178 – Logs parameter 0101...0178 .
6405 AL2 SIGNAL BASE
Defines the base value from which the percentage distribution is calculated.
• Representation and default value depends on the signal selected with parameter 6404 AL2 SIGNAL .
6406 PEAK VALUE
Detected peak value of the signal selected with parameter 6401 PVL SIGNAL .
6407 PEAK TIME 1
Date of the peak value detection .
• Format: Date if the real time clock is operating (dd .mm .yy) . / The number of days elapsed after the power-on if the real time clock is not used,
or was not set (xx d) .
6408 PEAK TIME 2
Time of the peak value detection .
• Format: hours:minutes:seconds .
6409 CURRENT AT PEAK
Current at the moment of the peak value (amperes) .
6410 UDC AT PEAK
DC voltage at the moment of the peak value (volts) .
