Tab. A-3: Common specifications (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 the optional brake resistor when regenerative energy
is large. A brake unit (FR-BU2) may also be used.
This protective function is available with the three-phase power input specification model
only.
This protective function does not function in the initial status.
When using the inverters at the ambient temperature of 40°C or less, the inverters can be
installed closely attached (0cm clearance).
The product may only be exposed to the full extremes of this temperature range for short
periods (e.g. during transportation).

You can select from among output frequency, motor current (steady), output voltage, frequency
setting, cumulative energization time, actual operation time, motor torque, converter output volt-
age, regenerative brake duty, electronic thermal relay function load factor, output current peak
value, converter output voltage peak value, motor load factor, PID set point, PID measured value,
PID deviation, inverter I/O terminal monitor, I/O terminal option monitor, output power, cumula-
tive power, motor thermal load factor, and inverter thermal load factor.
Fault definition is displayed when the protective function is activated,
the output voltage/current/frequency/cumulative energizing time right before the protection func-
tion was activated and the past 8 alarm definitions are stored.
