Meter output
0 to 10VDC, 1mA (programmable) : 2 points
Change between output frequency, output voltage, output current, DC voltage, etc.
Preventive Overcurrent limit (drive regeneration limit variable), overvoltage limit, overload warning
contact
Shut-off Overcurrent, overvoltage, undervoltage, IGBT fault, overload, temperature rise, ground
fault, other self-diagnosis
Fault history Past four faults are saved.
Saved details: Primary cause, secondary cause, output current and output frequency
before shut-off.
Overload withstand 150% for 1 minute, 170% for 2.5 seconds (50% of left values for 3Hz and less)
level Inverse time characteristics (variable torque)
120% for 1 minute, 125% for 1 seconds (75% of left value for 3Hz and less)
Inverse time characteristics (variable torque)
Retry Randomly set between 0 and 10 times
