Item Specifications Remarks
Frequency jump
control
• Jump frequency (3 points) and jump hysteresis width (1 point) can be pre-
set.
Restart after
momentary
power failure
• Drive restarts without causing drive-trip when power supply recovers.
Control
PID control • PID control function is provided standard.
Enclosure
(IEC 60529)
• IP20
Cooling method • Natural cooling for 1 HP or less, Fan cooling for 2 HP or more
Running,
stopped
• Output frequency, output current, and PID reference value/feedback value
The CRG lamp is on when the capacitor is charged.
Program mode • Function code and data code
Tripped [Cause of trip by code]
• OC1 (Overcurrent: during acceleration)

Indication
Running,
Tripped
• Fault history data is stored and indicated for the past four trips. Data is
retained while power is off.
