*1 Available when a Vector control compatible option is installed.
*2 In the initial setting, the starting torque is limited to 150% by the torque limit level.
*3 Applicable to conditions for a short time, for example, in transit.
*4 For installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.
*5 Not activated in the inverter in the initial state.
*6 Values measured 1 m in front of the inverter and 1.6 m from the floor.
Max. 2.4 kHz via one terminal (for the indication of inverter output frequency).
The item for monitoring can be changed using Pr.54 FM/CA terminal function selection.
Max. 20 mADC via one terminal (for the indication of inverter output frequency).
The item for monitoring can be changed using Pr.54 FM/CA terminal function selection.
Max. 10 VDC via one terminal (for the indication of inverter output frequency).
The item for monitoring can be changed using Pr.158 AM terminal function selection.
Output frequency, output current, output voltage, and frequency setting value are monitored.
The item for monitoring can be changed using Pr.52 Operation panel main monitor selection.
When a protective function is activated, a fault indication is displayed and the output voltage, output
current, output frequency, cumulative energization time, date (year, month, day) and time at the
occurrence of the fault are stored. Each fault is recorded and the last 8 records can be displayed.
