Electronic thermal overload relay
Motor coasts to a stop at approx. 250% of inverter rated
current
Motor coasts to a stop after 1 minute at 150% of inverter
rated output current
Motor coasts to a stop if DC bus voltage exceed 820V
Protected by electronic circuit
Can be set to individual levels during accel / decel,
provided / not provided available during coast to a stop
Protected by electronic circuit (overcurrent level)
ON until the DC bus voltage becomes 50V or less.
Seven of the following input signals are selectable:
Forward / 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, UP/DOWN
command, self-test,PID control cancel, PID integral reset / hold,
Inverter overheat alarm
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
overtorque detection, during undertorque 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
,
frequency reference loss, Inverter overheat alarm
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, constant copy,
frequency reference with built-in potentiometer, Unit
selection for frequency reference setting/desplay
Stops when DC bus voltage is approx. 400V or less
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
