Pr. 244 Increase cooling fan life

Pr.244 Cooling fan operation selection

You can control the operation of the cooling fan (200V class 2.2K or more, 400V class 3.7K or more) built in the inverter.

Pr. 244 Setting

Description

The cooling fan operates at power on.

0Cooling fan on/off control invalid (The cooling fan is always on at power on)

Cooling fan on/off control valid

 

The fan is normally on during inverter

operation. The fan switches on/off according to

 

the temperature during a stop of the inverter

 

whose status is monitored.

Pr.247

Constant-output region slip compensation selection

The inverter output current may be used to assume motor slip to keep the motor speed constant.

Pr. Selection of motor stopping 250 method and start signal

Pr.250 Stop selection

Used to select the stopping method (deceleration to a stop or coasting) when the start signal turns off.

Used to stop the motor with a mechanical brake, etc. together with switching off of the start signal.

You can also select the operations of the start signals (STF/STR).

Input/output phase failure

251, 872 protection selection

Pr.251 Output phase failure protection selection

Pr.872 Input phase failure protection selection

You can disable the output phase failure protection function that stops the inverter output if one of the inverter output side (load side) three phases (U, V, W) opens.

The input phase failure protection selection of the inverter input side (R/L1, S/L2, T/L3) can be made valid.

Pr.257 Control circuit capacitor life display Pr.258 Main circuit capacitor life display Pr.259 Main circuit capacitor life measuring

Degrees of deterioration of main circuit capacitor, control circuit capacitor or inrush current limit circuit and cooling fan can be diagnosed by monitor.

When any part has approached the end of its life, an alarm can be output by self diagnosis to prevent a fault.

(Use the life check of this function as a guideline since the life except the main circuit capacitor is calculated theoretically.)
