E1: V/f Pattern Characteristics
Use E1 parameters to set V/f characteristics for the motor.
E1-01
Input Voltage Setting
This parameter must be set to the power supply voltage. It sets the maximum
and base voltage used by preset V/f patterns (E1-03 = 0 to E) and adjusts levels
used by certain functions.
WARNING!
Drive input voltage (not motor voltage) must be set in E1-01 for
the protective features of the drive to function properly. failure to do so may
result in equipment damage and/or death or personal injury.

E1-04
Max Output Frequency
These parameters are only applicable when E1-03 is set to F. To set linear V/
f characteristics, set the same values for E1-07 and E1-09. In this case, the
setting for E1-08 will be disregarded. Ensure that the four frequencies are set
according to these rules:
E1-04 ≥ E1-06> E1-07 ≥ E1-09
