 Pr.05-26–05-30 records the amount of power the motors consume. The accumulation begins
when the drive is activated and the record is saved when the drive stops or turns OFF. The
amount of consumed watts continues to accumulate when the drive is activated again. To clear
the accumulation, set Pr.00-02 to 5 to return the accumulation record to 0.
 The accumulated total watts of the motor per second = Pr.05-27 × 65536 + Pr.05-26
 Example: when Pr.05-26 = 2548.1 and Pr.05-27 = 15.2, the accumulated total watts of the motor
per second = 15.2 × 65536 + 2548.1 = 996147.2 + 2548.1 = 998695.3
 The accumulated total kilowatts of the motor per hour = Pr.05-30 × 65536 + Pr.05-29
 Example: when Pr.05-29 = 3361.4 and Pr.05-30 = 11.2, the accumulated total kilowatts of the
motor per hour = 11.2 × 65536 + 3361.4 = 734003.2 + 3361.4 = 737364.6
05-31
Accumulated Motor Operation Time (minutes)
Default: 0

05-32
Accumulated Motor Operation Time (days)
Default: 0

0–65535
 Use Pr.05-31 and Pr.05-32 to record the motor operation time. To clear the operation time, set
Pr.05-31 and Pr.05-32 to 0. An operation time shorter than 60 seconds is not recorded.
