5.5 E: Motor Parameters
E parameters cover V/f pattern and motor data settings.
u E1: V/f Pattern for Motor 1
n E1-01: Input Voltage Setting
Set the input voltage parameter to the nominal voltage of the AC power supply. This parameter adjusts the levels of some
protective features of the drive (overvoltage, Stall Prevention, etc.).
NOTICE: Set parameter E1-01 to match the input voltage of the drive. Drive input voltage (not motor voltage) must be set in E1-01 for
the protective features to function properly. Failure to set the correct drive input voltage will result in improper drive operation.
E1-01 Related Values
The input voltage setting when using a 400 V class drive will change the undervoltage detection level for Uv1 and the
KEB function as follows:
Note: The braking transistor operation levels are valid for the drive internal braking transistor. If an external CDBR braking chopper is
used, refer to the instruction manual of that unit.
n V/f Pattern Settings (E1-03)
The drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency
reference.
One custom V/f pattern can be set up by programming parameters E1-04 through E1-13.
n
E1-03: V/f Pattern Selection
This parameter can only be set to F.
n
V/f Pattern Settings E1-04 to E1-13
Using parameters E1-04 through E1-13, the user can either monitor the V/f pattern values if set up a custom V/f pattern
as shown in Figure 5.44 for an example custom V/f pattern.
Note: Certain E1- parameters might not be visible depending on the selected control mode. Refer to Parameter Table on page 367
for details.
