*1. When undervoltage or instantaneous power failure occurs, no alarm output is provided
but the output is shut off. After power restoration, the inverter may be run as it is.
Depending on the running status (e.g. load magnitude), however, overcurrent,
regenerative overvoltage or other protection may be activated at power restoration. (in the
external operation mode)
*2. The braking torque indicated is a short-duration average torque (which varies with motor
loss) when the motor alone is decelerated from 60Hz in the shortest time and is not a
continuous regenerative torque. When the motor is decelerated from the frequency higher
than the base frequency, the average deceleration torque will reduce. Since the inverter
does not contain a brake resistor, use an optional brake resistor when regenerative
energy is large. (Available for the FR-S520E-0.4K to 3.7K only.) A brake unit (BU) may
also be used.
*3. Compatible with only the product having the built-in cooling fan.
*4. Available for the FR-S520E-0.4K to 3.7K only.
*5. Activated only when "1" is set in Pr. 40 "start-time earth (ground) fault detection
selection".
*6. Activated only when external thermal relay input (OH) is selected in any of Pr. 60 to Pr. 63
(input terminal function selection).
*7. Temperature applicable for a short period such as transportation.
Maximum and minimum frequency settings, frequency jump
operation, external thermal relay input selection, automatic
restart after instantaneous power failure, forward/reverse
rotation prevention, slip compensation, operation mode
selection, PID control, computer link operation (RS-485).
1 open collector signal can be selected from
among inverter running, up-to-frequency,
frequency detection, overload warning, zero
current detection, output current detection, PID
upper limit, PID lower limit, PID forward/reverse
rotation, operation ready, current average value
monitor signal, maintenance timer alarm, minor
failure and alarm. 1 contact output (1
changeover contact, 230V 0.3AAC, 30V
0.3ADC) signal can be selected.
1 signal can be selected from between output frequency and
motor current. Pulse train output (1440 pulses/s, 1mA full
scale)
