<1> The braking transistor operation level.   
■  V/F Pattern Setting( d1-01)       
The  set  V/F  pattern  determines  the  output  voltage  according  to  the  frequency  command. 
There are 15 different preset V/F patterns (setting 0 to E: only the maximum voltage and base 
voltage can be changed) and user-defined V/F patterns d1-02 to d1-11 (setting F).   
  d1- 01  V/F Pattern Selection     
Selects 1 V/F pattern from the preset 15 ones or sets the user-defined V/F pattern.   
<1> This will not be reset by A1-03 (Reset).   
<2> In Vector Control, d1-01 =F.   
□  Preset V/F Pattern Selection (Setting Value 0 to E) 
The preset V/F patterns are listed in Table 6.13. Select the appropriate V/F pattern and set to 
this parameter. d1-02 to d1-11 cannot be edited.   
Note: 
1. An improper V/F could cause motor undertorque or increased current because of overexcitation. 
2. d1-01 will not be reset by A1-03 (Reset).
