PARAMETERS

(3) Operation procedure

1)Operation procedure for running Operation pattern

Switch power on.

Set parameters.

Start, inverter operation

Constant-speed operation, commercial power supply operation

Deceleration (stop), inverter operation

!Pr. 135 = "1" (inverter's open collector output terminals)

!Pr. 136 = "2.0 s"

!Pr. 137 = "1.0 s" (Set the value equal to or longer than the time from when MC3 switches on actually until the inverter and

motor are connected. If it is shorter, restart may not function properly.)

!Pr. 57 = "0.5 s"

!Pr. 58 = "0.5 s" (Always set this parameter when commercial power

supply operation is switched to inverter operation.)
