Protective Functions
Motor Overload Protection Electronic thermal overload relay
Instantaneous Overcurrent
Motor coasts to a stop at approx. 200% of inverter rated
current
Overload
Motor coasts to a stop after 1 minute at 150% of inverter rated
output current
Overvoltage Motor coasts to a stop if DC bus voltage exceed 410V
Undervoltage
Stops when DC bus voltage is approx. 200V or less (approx.
160V or less for single-phase series)
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
Individual levels during accel/running, enable/disable provided
during deceleration
Cooling Fan Fault Protected by electronic circuit (fan stalling detection)
Ground Fault Protected by electronic circuit (rated output current level)
Other Functions
Power Charge Indication
RUN lamp stays ON or digital operator LED stays ON.
(Charge LED is provided for 400V)
ON until the DC bus voltage becomes 50V or less.
Input Signals
Multi-function Input
Four of the following input signals are selectable: Reverse run
(3-wire sequence), fault reset, external fault (NO/NC contact
input), multi-step speed operation, Jog command, accel/decel
time select, external baseblock (NO/NC contact input), speed
search command, accel/decel hold command, LOCAL/
REMOTE selection, communication/control circuit terminal
selection, emergency stop fault emergency stop alarm
Output Signals
Multi-function Output
Following output signals are selectable (1 NO/NC contact
output):
Fault, running, zero speed, at frequency, frequency detection
(output frequency ≤ or ≥ set value), during over torque
detection, minor error, during baseblock, operation mode,
inverter run ready, during fault retry, during UV, during speed
search, during speed search, data output through
communication
Standard Functions
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).]
