* 1. The factory setting will change when the control method is changed. The V/f control factory settings are given.
* 2. The factory settings depend upon the Inverter capacity. The values for a 200 V Class Inverter of 0.4 kW are given.
* 3. When C6-01=1, the upper limit is 120 %.

Min. base-
block time
Sets the Inverter's minimum
baseblock time in units of one
second, when the Inverter is
restarted after power loss ride-
through.
Sets the time to approximately
0.7 times the motor secondary
circuit time constant.
When an overcurrent or over-
voltage occurs when starting a
speed search or DC injection
braking, increase the set values.
