L2-03 Min. baseblock time 0.0 to 5.0 s 0.5 B B
D The factory setting depends on the Inverter capacity. The factory setting shown in the table is for a
200 V class, 0.4 kW Inverter. (See page NO TAG.)
D This setting is used with the speed search and DC injection braking functions.
D Set the time required for the leakage voltage to dissipate. Increase the setting if an overcurrent (OC)
occurs when the speed search or DC injection braking function starts.
D Set the baseblock time during winding change. Time for winding change varies according to the set-
ting. (For example, lower the setting, and time for winding change is also reduced.) Overcurrent (OC)
might occur if setting is too low.
D This setting is valid for speed searches performed after a momentary power loss and regular speed
searches.

L2-04 Voltage recovery time 0.0 to 5.0 s 0.3 A A
D Set the time allowed for the normal voltage to be restored after completion of the speed search.
For a 200 V class Inverter, this is the time in seconds for voltage to be restored from 0 VAC to 200 VAC.
For a 400 V class Inverter, this is the time in seconds for voltage to be restored from 0 VAC to 400 VAC.
D This setting is valid for speed searches after a momentary power loss, regular speed searches, the volt-
age changes with energy-saving control, and the voltage changes with baseblock clearing.
D Set the voltage recovery time after baseblock during winding change. Ovrevoltage (OV) might occur
if setting is too low.

7.4.2 Wiring for Winding Change
The VS-626MC5 offers two different types of winding changes, external winding change and auto- wind-
ing change. W-winding and -winding can be set independently using constants for motor 1 and 2.
J External Winding Change Method
In this method, an external signal is given to one of the multi-function inputs (set as “80H”) to start the
winding change. The external signal is given from the CNC.
