 Pr. 05-26~05-30 records the amount of power consumed by motors. The accumulation begins
when the drive is activated and record is saved when the drive stops or turns OFF. The amount
of consumed watts will continue to accumulate when the drive is activated again. To clear the
accumulation, set Pr. 00-02 to 5 then the accumulation record will return to 0.
 Accumulated total watts of motor per second = Pr. 05-27 x 65536 + Pr. 05-26
Example: When Pr. 05-26 = 2548.1 and Pr. 05-27 = 15.2, the accumulated total watts of motor
per second = 15.2 x 65536 + 2548.1 = 996147.2 + 2548.1 = 998695.3
 Accumulated total kilowatts of motor per hour = Pr. 05-30 x 65536 + Pr. 05-29
Example: When Pr. 05-29 = 3361.4 and Pr. 05-30 = 11.2, the accumulated total kilowatts of
motor per hour = 11.2 x 65536 + 3361.4 = 734003.2 + 3361.4 = 737346.6
Accumulative Motor Operation Time (Min.)
Factory Setting: 0
Settings 00~1439
Accumulative Motor Operation Time (Day)
Factory Setting: 0
Settings 00~65535
 Pr. 05-31 and Pr. 05-32 are used to record the motor operation time. To clear the operation time,
set Pr. 05-31 and Pr. 05-32 to 00. Operation time shorter than 60 seconds will not be recorded.
Full-load Current of Induction Motor 3 (A)
Unit: Ampere
Factory Setting: #.##
Settings 10~120 % of drive’s rated current
 Set this parameter according to nameplate of motor. The factory setting is 90 % of rated current.
Example: The rated current of 7.5 HP (5.5 kW) is 25 A, the factory setting is 22.5 A.
The setting range will be 2.5~30 A. (25 × 10 % = 2.5 A and 25 × 120 % = 30 A)

Rated Power of Induction Motor 3 (kW)
Factory Setting: #.##
Settings 0~655.35 kW
 It is used to set rated power of motor 3. Factory setting is the power value of drive.

Rated Speed of Induction Motor 3 (rpm)
Factory Setting: 1710
Settings 0~65535
1710 (60 Hz 4 poles); 1410 (50 Hz 4 poles)
 It is used to set the rated speed of the motor according to motor nameplate.
