Protective Functions
Motor Overload Protection Electronic thermal overload relay
Instantaneous Over Current
Motor coasts to a stop at approx. 250% of inverter rated
current
Overload
Motor coasts to a stop after 1 minute at 150% of inverter
rated output current
Over Voltage Motor coasts to a stop if DC bus voltage exceed 820V
Under Voltage Stops when DC bus voltage is approx. 400V or less
Momentary Power Loss
Following items are selectable: Not provided (stops if
power loss is 15ms or longer), continuous operation if
power loss is approx. 0.5s or shorter, continuous operation
Cooling Fin Overheat Protected by electronic circuit
Stall Prevention Level
Can be set to individual levels during accel/decel,
provided/not provided available during coast to a stop
Cooling Fan Fault Protected by electronic circuit (fan lock detection)
Ground Fault Protected by electronic circuit (over current level)
Power Charge Indication ON until the DC bus voltage becomes 50V or less.

command, self-test, PID control cancel, PID intregal reset/
hold
Output Signals
Multi-function Output
Following output signals are selectable (1 NO/NC contact
output, 2 photo-coupler outputs): Fault, running, zero
speed, at frequency, frequency detection (output
frequency
≤
or
≥
set value), during over torque detection,
during under voltage detection, minor error, during
baseblock, operation mode, inverter run ready, during fault
retry, during UV, during speed search, data output through
communication, PID feedback loss detection
Standard Functions
Voltage vector control, full-range automatic torque boost,
slip compensation, DC injection braking current/time at
start/stop frequency reference bias/gain, MEMOBUS
communications (RS-485/422, max. 19.2K bps), PID
control, energy-saving control, parameter copy, frequency
reference with built-in potentiometer, Unit selection for
frequency reference setting/display
