Undervoltage Detection Lvl (Uv1)

Sets the voltage at which a Uv1 [DC Bus Undervoltage] fault is triggered or at which the KEB function is activated. Usually it is not necessary to change this setting.

Determined by o2-04 and E1-01

(200 V Class: 150 - 210 V, 400 V Class: 300 - 420 V)

Notice

Damage to Equipment

When you set this parameter to a value lower than the default, you must install an AC reactor on the input side of the power supply.

If you do not install an AC reactor, it will cause damage to the drive circuitry.

Note:

If the low voltage detection level is near the lower limit value of L2-05, the drive will detect Uv1 during KEB Ride-Thru operation. Do not set the value too low when you use the KEB Ride-Thru function.
