Capacity measurement procedure
1. To compare with the default value measured at the time of shipment from the factory, return the
state of the actual product to the state during shipment from the factory.
•
If another inverter is connected to the main circuit terminals P(+) and N(-) via a DC bus line, dis-
connect it. A DC reactor (option), even if connected, need not be removed.
• Remove the wires of the control power auxiliary inputs (R0, T0).
• Turn OFF all digital inputs (DI1 to DI7) of the control circuit terminals.
• Make the setting to ensure that the transistor output (DO1) and relay output (ROA, ROB) do not
turn ON.
• If the setting is made to perform logical inversion of the transistor output and relay output, the
output turns ON even when the inverter is not running. In such a case, change the setting.
• Ensure an ambient temperature of 25℃±10°C.
2. Turn ON the main power supply.
3. Make sure the cooling fan is operating and the inverter is in a stopped state.
4. When the main power supply is cut off, the measurement of the capacity of the main circuit capaci-
tor starts automatically.
5. Once the display on the LED is cleared, again turn ON the main power supply.
6. Check Main Circuit Capacitor’s Capacitor Monitor (3010Hex-4CHex).
Method of Measuring the Capacity of the Main Circuit Capacitor
when Power Supply is Cut Off during Normal Operation
The capacity of the main circuit capacitor in the normal operation state is measured automatically
when the power supply is cut off, if bit 3 = 1 at Protection/Maintenance Function Mode Selection
(3008Hex-63Hex).
T
o perform this measurement, it is necessary to measure the reference capacitor capacity according to
the measurement procedure below.
