Speed Search Control Level; Minimum Baseblock Time; V/F Characteristics During Speed Search; Stop Compensation Time - Omron SYSDRIVE 3G3HV SERIES User Manual

Preparing for Operation
• Select with n051 a method to process instantaneous power failure.
Set Values
Set value
0 Inverter will discontinue running.
1 Inverter will continue running if power is supplied again within instantaneous power failure
compensation time set with n055. (see note 1)
2 Inverter will always continue running without detecting UV1 or UV3. (see notes 1 and 2)
Note 1. Keep the run command ON to permit the Inverter to restart operation automatically when
power is supplied to the Inverter after the operation of the Inverter is interrupted due to an
instantaneous power failure.
Note 2. If n051 is set to 2, the Inverter will restart running after supply voltage to the Inverter returns to
normal and the Inverter will not detect error output signals.
n052

Speed Search Control Level

Setting range 0 to 200
• Set with n052 a current level in 1% units based on the rated output current as 100% which enables the
Inverter to determine the completion of the speed search control.
• It is usually not necessary to change the default-set value.
• To permit the Inverter to use the speed search function, set the multi-function input parameter used by
the Inverter to 15 or 16 so that the speed search command will be input to the Inverter.
• When the output current becomes less than the value set with n054, the Inverter in speed search con-
trol will detect the synchronous speed and the Inverter will be in acceleration mode.
n053

Minimum Baseblock Time

Setting range 0.5 to 10.0
Note The default-set value varies with the Inverter model.
• Set with n053 time in 1-s units to start the speed search control after RUN input is ON and instanta-
neous power failure processing starts. Refer to page 3-70, Speed Search Command .
n054

V/f Characteristics During Speed Search

Setting range 0 to 100
Note The default-set value varies with the Inverter model.
• Set percentage of V/f characteristics for speed search.
• It is usually not necessary to change the default-set value.
n055

Stop Compensation Time

Setting range 0.0 to 2.0
Note The default-set value varies with the Inverter model.
