Specifications
Note 1. The required capacity at the facility is the capacity for the Inverter's rated output. It depends
on the impedance at the input power supply. (The input power supply's power factor fluctu-
ates, so it can be improved by inserting an AC reactor.) There will also be variations in the
ratio between the rated current of the motor that is used and the rated output current of the
Inverter.
Note 2. The heat radiation is the electric power consumed in the Inverter at the Inverter's rated out-
put. (It is calculated by subtracting the output power from the input power under rated oper-
ating conditions.)
Protective
functions Motor protection Protection by electronic thermal
Instantaneous overcurrent protec-
tion Stops at approx. 250% of rated output current.
Overcurrent protection Stops in 1 min at approximately 150% of rated output cur-
rent.
Overvoltage protection Stops when main-circuit DC voltage is approximately 410 V
min.
Undervoltage protection Stops when main-circuit DC voltage is approximately 200 V
max.
Momentary power interruption
restart selection Select between none (stops at 15 ms or longer), continue
operation if power is restored within approx. 0.5 s, or con-
tinue operation regardless of length of interruption.
Radiation fin overheated Temperature is detected by a thermistor.
Grounding protection Protected by overcurrent protection.
Charge indicator The data display will flash until the main circuit DC voltage
is 60 V or less.
